Abstract

Lung cancer is a substantial health issue globally, and it is one of the main causes of mortality. Malignant mesothelioma (MM) is a common kind of lung cancer. The majority of patients with MM have no symptoms. In the diagnosis of any disease, etiology is crucial. MM risk factor detection procedures include positron emission tomography, magnetic resonance imaging, biopsies, X-rays, and blood tests, which are all necessary but costly and intrusive. Researchers primarily concentrated on the investigation of MM risk variables in the study. Mesothelioma symptoms were detected with the help of data from mesothelioma patients. The dataset, however, included both healthy and mesothelioma patients. Classification algorithms for MM illness diagnosis were carried out using computationally efficient data mining techniques. The support vector machine outperformed the multilayer perceptron ensembles (MLPE) neural network (NN) technique, yielding promising findings. With 99.87% classification accuracy achieved using 10-fold cross-validation over 5 runs, SVM is the best classification when contrasted to the MLPE NN, which achieves 99.56% classification accuracy. In addition, SPSS analysis is carried out for this study to collect pertinent and experimental data.

1 Introduction

It is widely accepted that all malignant mesotheliomas (MMs) are rare, serious malignancies with a clear connection to asbestos exposure. Additionally, a “genetic predisposition” and a previous “simian virus 40” infection are likely related to it. In some Turkish regions where low concentrations of erionite, a naturally fibrous substance that belongs to the group of minerals known as zeolites, are prevalent, the frequency of MM is extremely high. In Turkey, atmospheric “asbestos exposure and MM” are two of the most serious public health issues. The formation of mesothelioma can sometimes be linked to molecular pathways. Staying in the country has been associated with the emergence of mesothelioma. Asbestos-containing soil combinations referred to as “white soil” or “corak” may be observed in Anatolia, Turkey, Luto, and Greece. MM is a deadly cancer that is becoming more common as a result of asbestos exposure. Individual patients may benefit from chemotherapeutic, radiation, or immunotherapy, and some patients may benefit from surgical treatment and multimodality therapy. In the overall population, MM is an uncommon illness with an estimated “incidence of 1–2 per million” each year. In developed nations, MM in women varies from 1 to 5 per million annually, whereas in men it varies between 10 and 30 per million each year [1]. It is possible that asbestos exposure could be the reason for the higher occurrence rates in developed nations. MMs are estimated to be associated with 15,000–20,000 fatalities every year throughout the world, according to current research. In Turkey, approximately 1,000 individuals are diagnosed with MM each year.

The diagnosis of myeloma is mostly dependent on blood and urine testing. Myeloma cells typically release M protein, an antigen known as monoclonal immunoglobulin. The amount of M protein in a patient’s blood and urine is used to determine the illness’ severity, monitor the efficacy of treatment, and observe for disease progression or recurrence. To examine the number of antibodies in the blood, immunoglobulin levels are tested. Blood tests are used to determine the serum levels of albumin and 2-M. Lactase dehydrogenase (LDH) is a protein-type enzyme, and almost all body tissues contain it. An X-ray produces a picture of the interior of the body’s organs using a low amount of radiation. X-ray of the patient’s bones for a doctor’s evaluation of their skeletal system is often the initial step in the analysis of the bones when myeloma is found or diagnosed. Instead of using X-rays, magnetic resonance imaging (MRI) creates precise pictures of the body using magnetic fields. Particularly in the skull, spine, and pelvis, an MRI can reveal if the healthy bone marrow has been replaced with myeloma cells or by a plasmacytoma. A plasma cell tumor called a plasmacytoma develops in bone or soft tissue. Fine-grained imaging could potentially reveal spinal compression fractures or a tumor pushing against the nerve roots. A comprehensive cross-sectional image of soft tissue anomalies or cancers can be obtained by computed tomography (CT) scan. A computer then combines the photos to produce a three-dimensional model of the interior of the body. It is crucial to stress that people with multiple myeloma should avoid intravenous contrast dye, which is frequently used in CT scans for other types of malignancies.

A positron emission tomography (PET) scan, often known as a PET-CT scan, is a combination of PET and a CT scan. A PET scan is a technique for creating images of organs and tissues inside the body. Aspiration and biopsy of bone marrow are the two procedures comparable and are frequently performed concurrently to check the bone marrow. Bone marrow is composed of both solid and liquid components. A needle is used to extract a sample of the bone marrow fluid. A needle biopsy of the bone marrow is the removal of a tiny quantity of solid tissue. This is critical in making a diagnosis of myeloma. The material is next examined by a pathologist. A pathologist is a physician who specializes in the interpretation of laboratory tests and the evaluation of cells, tissues, and organs to diagnose illness. To assess the genes in myeloma, cytogenetics and a specific test known as fluorescence in situ hybridization are performed. These tests determine the genetic makeup of the myeloma and whether it is high or low risk. Additionally, samples may be examined using genomic sequencing to determine exactly the deoxyribonucleic acid (DNA) changes that have occurred in the cancer cells. A bone marrow extraction and biopsy are frequently performed on the pelvic bone, which is located in the lower back near the hip. Anesthesia is used to numb the skin in that location first. The perception of pain may also be suppressed using other anesthetic techniques.

1.1 Background of research

The planet’s average lifespan increased in the later part of the twentieth century. Revolutionary therapies for infectious illnesses, such as dengue fever and cholera, as well as improved sanitation practices, have significantly reduced health hazards. Cancer, on the other hand, continues to be a major global health concern. According to records, there have been 23,869 fatalities in America, 12,012 mortalities in Asia, and 49,779 casualties in Europe due to MM in 2018. MM is caused by mesothelial cells attacking the peritoneal, alveoli, and endocardium. Inflammatory and infectious diseases are two common MM symptoms. From 1980 to 2020, the worldwide death rate owing to MM increased to a catastrophic level [2]. After the first asbestos exposure, mesothelioma symptoms might take 10–50 years to appear. Early identification might be more difficult by symptoms that are frequently confused with less severe conditions. Patients should seek medical assistance as soon as symptoms appear since early discovery may improve the prognosis for mesothelioma. Chest discomfort or abdominal pain, shortness of breath, lack of appetite, blood clots, coughing up blood, fluid accumulation, fatigue, fever and night sweats, and weight loss are all common symptoms of mesothelioma. Dry coughing, chest discomfort, breathlessness, pulmonary edema, and joint stiffness are also frequent early signs. Weight loss, excessive sweating, tiredness, difficulty breathing, temperature, swallowing, and cerebral hypoxia are also indications of the later stages. In general, etiology examines the link between illness and the variables that influence it, such as nutrition, climate, genetic makeup, and lifestyle. Finding valuable information from a large amount of data via manual calculation is difficult. Previous research has shown that association rule mining may be used to derive disease risk variables. The huge amount of biostatistics and medicinal data has made data analysis more difficult and time-consuming for medical practitioners and scientists [3]. Bioinformatics potential is expanded by improved DNA scanning and machine intelligence tools. In addition to medicine, biomedical research, training, automation, commerce, and machine learning approaches are frequently employed. Data mining (DM) is the process of extracting usable information from the data. Segmentation, categorization, analysis, and DM techniques are some of the methodologies and algorithms used in DM. In medical statistics, there is a large class discrepancy. Categories are not reflected evenly in medical diagnostic systems. Minority categories have several minor instances that are pervasive in health diagnosing procedures. The targeted category, patient/malignant, appears substantially less often in such scenarios than genuine/normal specimens [4]. DM is a method for extracting knowledge from data. For effective knowledge retrieval, it applies a variety of techniques and algorithmic techniques to pre-process, cluster, classify, and associate the data. Examining and interpreting the hazy medical data provide outstanding and huge potential for DM. The basic medical data, however, are many, geographically distributed, and of various forms. These data must be compiled in an orderly manner. Thanks to DM’s creativity and intelligence, a customer may deal with contemporary and obscure patterns in the data. There are several advantages to using DM in a medical context and it has many applications, the most important among which is that it leads to better medical treatment at a lower cost. Because DM algorithms provide a learning-rich environment that can improve the accuracy of therapeutic decisions, they are mostly utilized in the detection and treatment of cancer. DM techniques are often divided into two categories: unsupervised learning, or descriptive models, which explore the relationships between qualities and find patterns in the data, and supervised learning; or predictive models, which predict future outcomes based on past behavior. Condensing a theory, acquiring data, pre-handling, evaluating the model, and interpreting the model are all integrated within the DM method.

The lower categories are mostly ignored by traditional classifiers, which focus on the larger ones. “Typically, a large number of current solutions are suggested at the database level, whereas just a small number of existing algorithms are proposed.” Those services are based on interpolation, such as oversampling as well as under-sampling approaches, at the database level.

Whenever a patient visits the hospital to have their symptoms examined, they are frequently diagnosed and treated. Shortness of breath, heart or back discomfort, pain, chronic coughing, and a variety of other signs may be experienced by patients, neither of which instantly alert the clinician to mesothelioma. Numerous clinical investigations on MM illness have been conducted in southeast Turkey. Many studies employing artificial intelligence approaches, including probability neural networks (PNNs), learning vector quantization (LVQ), artificial immune system (AIS), and multilayer neural network (MLNN) incorporating prospective information, have been conducted on MM illness diagnosis. The PNN structures use a methodology known as Bayesian classifiers, which was created in statistics, to offer a generic answer to pattern classification issues. Within a pattern layer, the PNN creates distribution functions using a supervised training set. Compared to other ANN structures, PNN training is a lot easier. However, if the categorization of the categories is different while also being quite similar in certain regions, the pattern layer may be rather large. PNN is suitable for disease diagnosis systems because it provides a general solution to pattern categorization issues. The LVQ neural network (NN) topology is classified according to how much the unknown data resemble these prototypes. An LVQ NN consists of a linear output layer and a competitive layer. The capability to classify input vectors is picked up by the competitive layer. The linear output layer transforms the classes of the competitive layer into user-defined target categories. Target classes for the linear output layer are the classes it learns, whereas subclasses for the competitive layer are the classes it learns. The LVQ network design has been successful for disease diagnosis systems. The most prevalent NN structure that has been employed effectively for illness diagnostic systems is the MLNN structure. The back-propagation technique is a well-known and effective tool for MLNN structure training. Drugs are used in immunotherapy to boost a person’s immune system so it can more effectively detect and eliminate cancer cells. An essential component is the immune system’s ability to stop attacking healthy body cells. “Checkpoints,” which are proteins on immune cells, need to be activated for an immune response to occur (or off). Cancer cells occasionally employ these checkpoints to stave off immune system assaults. Restoring the immune response against cancer cells may benefit from the use of checkpoint inhibitors, more contemporary drugs that directly target these checkpoint proteins.

The diagnosis of MM illness is a crucial classification problem. In many different professions, such as healthcare, categorization is a vital element of the process [5]. Artificial intelligence approaches are increasingly being used in medical diagnostics. The most essential components in diagnosing are, undoubtedly, the analyses of data collected from patients and professional choices. Therefore, multiple artificial intelligence approaches may be required to categorize illnesses at times. DM is used extensively in clinical uses such as diagnostics, prediction, and treatment. Medical information extraction is the term for using DM in healthcare applications (CDM). For practical knowledge-building, healthcare decisions, and critical evaluation, CDM entails the conceptualizing, acquisition, evaluation, and assessment of accessible clinical data. DM focuses on clinical diagnostics among the many clinical applications [6]. Diagnosing a disease is determining if an affected person has a certain problem based on medical indications, behaviors, and testing. Clinical decision support systems (CDSSs), or more particularly diagnosing decision support systems, are computer programs that assist with this process. A number of computerized and non-computerized tools and treatments are included in clinical decision support (CDS). To fully benefit from electronic health records (EHRs) and automated physician order input, high-quality CDSSs, also known as computerized CDS, are required. A CDSS may consider all data included in the EHR, making it feasible to recognize changes outside the purview of the expert and recognize changes particular to a particular patient, within reasonable bounds. Clinical data are increasing in quantity and quality and can be found in EHRs, disease registrations, patient surveys, and information exchanges. However, improved patient care is not necessarily a result of digitization and big data. A number of studies have found that just installing an EHR along with computerized physician order entry (CPOE) greatly increased the number of some errors and dramatically decreased the frequency of others. High-quality CDS is therefore essential if healthcare organizations are to benefit fully from EHRs and CPOE.

Support vector machine (SVM), one of the most widely used supervised learning algorithms, is used to handle classification and regression issues. Nonetheless, it is largely employed in machine learning classification issues. The SVM method seeks to construct the optimum line or decision boundary that can partition n-dimensional space into classes in order to quickly categorize fresh data points in the future. A hyperplane is a name given to this perfect decision boundary. SVM is used to choose the extreme vectors and points that contribute to the hyperplane. Support vectors, which are used to describe these extreme scenarios, are used in the SVM technique. A well-established study area in pattern recognition and machine learning is the combination of numerous classifiers (also known as an ensemble of classifiers, a committee of learners, a mixing of experts, etc.). It is understood that using many classifiers as opposed to a single classifier often increases overall predicted accuracy. Even while the ensemble may not produce results that are superior to the “best” single classifier in some circumstances, it may reduce or even remove the risk associated with selecting an insufficient single classifier. In order to create an ensemble, numerous separate classifiers must first be trained, and their predictions must then be combined. SVMs often have better prediction accuracy by default than multilayer perceptron. SVMs may take longer to execute because they need complex computations, such as applying kernel functions to translate an n-dimensional space. However, it consistently makes excellent forecasts. The complexity of MLP classifiers is managed by keeping the number of hidden units low, whereas the complexity of SVM classifiers is independent of the dimension of the tested data sets. SVMs employ empirical risk minimization, whereas MLP classifiers are based on the minimizing of structural risk. As a result, SVMs are effective and produce close to the best classification since they are able to obtain the ideal separation surface, which performs well on previously unknown data points.

The main goal of this research is to develop the best classification for MM illness diagnosis utilizing powerful DM approaches, as well as to try to uncover the relevant input factors for MM diagnosis of diseases. Several authors utilized different classification algorithms in this dataset to diagnose MM illness, although SVM and MPLE were most likely not utilized as a part of well-related capabilities. This study has the greatest categorization average accuracy (as compared to previous studies) and has a substantial variable input significance chart for MM illness diagnosis.

2 Literature review

MM is a malignancy that arises from mesothelial cells in the pleural membrane surface and intraperitoneal regions and is particularly aggressive. MM, which was once thought to be unusual, is becoming more common, with a maximum occurrence expected around 2010 and 2025. Even though the condition is uncommon, it is extremely serious, with a mean survival rate of only 7 months. Because the disease can take up to 50 years to manifest after asbestos exposure, indications are hazy, and diagnostic instruments are not sensitive or precise enough just to identify the illness until it becomes late. As a result, innovative MM early recognition and screening technologies are critically required to improve MM care [7]. A rare kind of cancer called mesothelioma is largely caused by asbestos exposure. After asbestos exposure, cancer may take decades to manifest, but once it does, the illness spreads swiftly. The majority of those who get mesothelioma have had jobs where asbestos fibers were inhaled. After a person is initially exposed to asbestos, the latency period – the interval between exposure and diagnosis – can be anywhere between 20 and 50 years. The pleural membranes of the body are affected by this form of malignancy. The stomach and chest chambers are lined with these membranes. Up to four out of every five occurrences of malignant mesothelioma involve the chest membranes. The fibers in asbestos are quite small and enter into the extreme ends of tiny air channels in the lungs when individuals inhale them in. The pleural membranes of the chest cavity can be reached by the fibers from there. They may be ingested and may ultimately find their way to the membranes lining the abdominal cavity after spending time in the stomach or other internal organs. Asbestos fibers induce inflammation and scarring after they have made contact with the membranes. This may result in DNA alterations and unchecked cell development, both of which increase the risk of cancer, including mesothelioma. Six distinct minerals that are found in the environment naturally are known as asbestos. Mesothelioma does not always occur in asbestos-exposure victims. The largest risk of contracting the disease is among those who have spent more than a year in employment involving a high level of asbestos exposure. However, mesothelioma can develop after just a few days of exposure. A membrane cancer called malignant mesothelioma is caused by asbestos exposure. Cancer that spreads to other parts of the body can originate anywhere. On the pleural membrane, it can develop tumors that resemble mesothelioma. Cancer that has migrated from its original site to another portion of the body is referred to as metastatic cancer or metastatic carcinoma, and usually, the lymphatic system is involved. After entering the lymph nodes, cancer cells can spread throughout the body and begin new tumors. The pleura is a membrane where pleural mesothelioma first appears. Metastatic cancer on the pleura and mesothelioma have extremely similar appearances. However, the medications used to treat pleural tumors caused by metastatic breast or colon cancer differ from those used to treat pleural mesothelioma. All cancers, including mesothelioma and metastatic cancer, show their origin. Typically, these are proteins. These indicators are known as “biomarkers” by scientists. Biomarkers might be observed in the tissue, blood, or other bodily fluids. All MMs displayed double negativity and all metastatic carcinomas displayed double positivity.

Even though MM must be distinguished from innocuous pleural disorder or metastatic spread of many other principal types of cancer toward the pleura, existing intrusive recognition processes, such as “pleural fluid cytogenetics acquired via thoracentesis,” syringe “biopsy of pleural muscle under CT guidance,” and “accessible thoracotomy,” possess poor susceptibility, varying from 0% with a solitary sample selection to 64% with sequential samplings. Utilizing molecular biomarkers to create a suitable and “non-invasive cancer diagnostic” test has shown to become a very appealing but tough undertaking. Several MM tumor indicators have been discovered. The majority are circulation proteins/antigens, which are either produced or degraded remains of tumor tissue and may be tested therapeutically using immunoassays. The most often used antigenic tumor determinants for identifying MM are soluble mesothelin-related protein (SMRP), megakaryocyte potentiating factor (MPF), and mesothelin (MSLN) variations. In the clinic, SMRP levels can now be measured, although the specificity and sensitivity are still low at 50 and 72%, respectively. MPF and MSLN research showed sensitivity and particularities of 74.2 and 90.4%, respectively, and 59.3 and 86.2% [8]. Even though these indicators have a high sensitivity and specificity, their sensitivity makes them ineffective as an MM diagnostic test.

According to the 2015 World Health Organization classification, patients are now divided into three classic histopathologic types: epithelioid MM (EMM), sarcomatoid MM (SMM), and biphasic MM (BMM), with BMM consisting of a mix of sarcomatoid and epithelioid features. The prognosis is greatest for patients with EMM (median overall survival [OS] of 16 months), worst for those with SMM (OS of 5 months), and in the middle for patients with BMM. This histological categorization is useful for prognosis and treatment, but it is inadequate to account for the wide range of clinical characteristics and health experiences in MM patients. This emphasizes the critical need for innovative strategies to uncover prognostic indicators that are reliably linked to survival. With the increase of deep learning as well as the accessibility of thousands of histological slides, a great beginning to reassess traditional techniques for diagnosis and patient outcome prediction has arisen [9]. Furthermore, this method is frequently regarded as a black box, with visual elements leading to projections that are difficult to understand. To overcome these restrictions, researchers created MesoNet, a deep learning method designed exclusively for analyzing huge photos, such as whole-slide images (WSIs), without the need for pathologists to annotate them locally [10]. Researchers developed a newly disclosed method particularly designed to meet this problem by creating MesoNet. The technique develops a deep learning algorithm using WSIs with only international data labeling to construct a forecasting model. “WSI’s from MM patients” were first normalized and separated into little “112 × 112 µm squares (224 × 224 pixels)” known as “tiles.” Throughout an adaptive learning experience, these tiles were supplied into the network infrastructure, which allocated a survival score to every tile. Ultimately, the model chose the most significant tiles from each WSI for the forecast and utilized this limited handful of tiles to forecast patient OS [11].

The purpose of most DM projects is to create a model from the data supplied. As a result, DM systems are scientific rather than subjective, as they are based on existing facts. Predictive DM incorporates a variety of approaches to create classification and regression models, including decision trees, random forests, boosting, SVMs, linear regression, and NNs. Cluster analysis and classification approach modeling are used in descriptive DM [12].

Three hundred- and twenty-four-MM patients were diagnosed and managed in this study. The files were analyzed and the data were examined retrospectively. All samples in the “dataset have 34 attributes” since the doctor believes it is more helpful than other factor subsets [13]. Age, gender, city, asbestos exposure, type of MM, period of asbestos exposure, prognosis method, keep side, cytology, the severity of symptoms, dyspnea, ache on chest, loss of strength, smoking habit, efficiency status, white blood cell count, hemoglobin, platelet count, sedimentation, blood lactic dehydrogenases (LDHs), alkaline phosphatase (ALP), protein content, total protein, glucose, pleural LDHs are all included. [14]. Each patient’s diagnostic tests were documented. The dataset for this work was obtained from the UCI Machine Learning Repository [15].

2.1 MM illness detection with DM methods

DM is a multi-step procedure that must be iterated. The “CRISP-DM,” an industry-supported “tool-neutral technique” (e.g., SPSS, DaimlerChrysler), splits a DM project into “six phases” (Figure 1).

Figure 1 
                  CRISP-DM tool [15].
Figure 1

CRISP-DM tool [15].

This work addresses steps 4 and 5, with an emphasis on applying NNs and SVMs to solve classification and regression issues. Both goals need supervised learning, where a model is developed using examples from a dataset to translate my input into a target. Models that deal with categorization produce a probability p(c) for each possible class c, such that c = 1 N c p c = 1 . Setting a decision threshold D [0, 1] and then returning c if “p(c) > D” is one option for assigning a target class c. This method is used to create the receiver operating characteristic (ROC) curves [16]. In order to create a multiclass confusion matrix, another option is to output the category with the highest probability.

Common criteria for judging classifier models include the ROC area (AUC), a confusion matrix, efficiency (ACC), and actual positive/negative rates (TPR/TNR). High ACC, true positive rate (TPR), TNR, and AUC values are desirable in a classification method. To measure the generalization performance of the model, the endurance verification (i.e., train/test split) or even the more robust k-fold cross-validation is typically utilized [17]. This is far more resilient, but it takes roughly k times as long to compute because there are k hypotheses to fit.

2.2 MLP and multilayer perceptron ensembles (MLPE) NN model

The famous multilayer perceptron is referred to as NN in DM approaches (MLP). MLPs are a good solution to address classification problems. The attempt to determine the correct network for a particular application due to susceptibility to the beginning circumstances and overfitting and underfitting difficulties that restrict their generalization potential is a fundamental worry in their utilization. Furthermore, in the search for a single ideal system, time and technology restrictions may severely limit the levels of flexibility. MLP ensembles are a potential solution to substantially address these problems; aggregating and voting approaches are widely utilized in conventional statistical pattern classification and may be successfully used in MLP classifications [17,18]. MLPEs, which are mixtures of MLP algorithms, are being used to solve frameworks for analysis, and it has been discovered that MPLEs outperform single MLP designs in many cases. The results of this study suggest that MLPEs outperform MLPs. One hidden state of H neurons with exponential functionalities is included in this system (Figure 2, left). The whole model is written as follows:

(1) y i = f i w i , 0 + j = I + 1 1 + H f j n = 1 I x n w m , n + w m , 0 w i , n .

Figure 2 
                  MLP NN (left) and SVM (right) [18].
Figure 2

MLP NN (left) and SVM (right) [18].

The platform’s response for component i, w i , j is the strength of the node-to-node link j to I, as well as f j has been the node j objective function. In the case of a classification algorithm ( N c = 2 ) , a logistic function is used by one of the output neurons. For tasks with several classes ( N c > 2 ) , there are N c SoftMax functions that are applied to convert the output of linear output neurons into class probabilities:

(2) p ( i ) = exp ( y i ) c = 1 N c exp ( y c ) .

While p ( i ) seems to be the predicted probability, and y i the instruction algorithm of BFGS is terminated when the defect slope approaches zero, or occasionally after an optimal number of M e epochs. When it comes to categorization, it maximizes the likelihood. Because NN training is not perfect, the final outcome is dictated by the beginning weights. To overcome this issue, either train a large number of systems and then select the one with the lowest error, or use an ensemble of all NNs and output the sum of the individual forecasts. The MLP model is the first alternative to NN in the DM approach, while the MLPE structure is the second. Ensembles are often superior to individual students [18]. The number of hidden networks has a significant impact on the final NN effectiveness. H = 0 is used in the basic NN, whereas a large H value is used in more complicated NNs. Due to sensitivity to initial circumstances and over-fitting and under-fitting issues that restrict its generalization potential, it is difficult to specify the appropriate network for a given application. Furthermore, time and technical restrictions may drastically limit the degrees of freedom available in the search for a single ideal network. MLPE may be utilized to partially address these disadvantages; averaging and voting approaches are routinely employed in traditional statistical pattern detection and may be successful for MLP classifiers. MLPEs, which are MLP model combinations, are used to address classification problems, and it has been discovered that MPLEs perform much better than any of its separate MLPs in many cases. One of the more well-liked and useful NN models is the MLP model. It is also among the easier models mathematically.

Learning is the combination of numerous classifiers (also known as an ensemble of classifiers, a committee of learners, a mixing of experts, etc.). It is understood that using many classifiers as opposed to a single classifier often increases overall predicted accuracy. Even while the ensemble may not produce results that are superior to the “best” single classifier in some circumstances, it may reduce or even remove the risk associated with selecting an insufficient single classifier. To create an ensemble, numerous separate classifiers must first be trained, and their predictions must then be combined.

2.3 SVM model

One benefit SVMs have over NNs is the absence of local minima during the learning process. The core concept is to use a regressive approach to project the input x into a high-dimensional feature collection. The SVM then identifies the optimal linear divergence hyperplane in the training dataset and connects it to a collection of vector support points (Figure 2, right). The conversion (x) is determined by a kernel function. The widely used Gaussian kernel, which has fewer variables than other kernels (such as polynomial), is employed in SVM as part of the sequential minimum optimization (SMO) learning technique:

K ( X , X ) = exp ( γ X X 2 ) , γ > 0 .

Two hyper-parameters influence the performance of the classifier: C is a penalty component and K is a kernel criterion. The conditional SVM outcome is as follows:

f ( x i ) = j = 1 m γ j α j K ( x j , x i ) + b ,

(3) p ( i ) = 1 / ( 1 = exp ( Af ( x i ) + B ) ) ,

where m denotes the number of “support vectors,” y i { 1,1 } seems to be the binary classifier outcome, b similarly seems to be the model’s components, and A and B are model parameters, and they are obtained by addressing a regularized supervised classification issue. Whenever N c > 2 , the one-against-one method is employed, which involves training N c ( N c 1 ) nearest-neighbor coupling to provide the output for the classification algorithm.

The NN and SVM model parameters (e.g., H, γ ) are tuned using an exhaustive search in the suggested DM approach. The test data are further separated into training and testing sets (remaining members) or an inner k-fold is utilized to avoid overfitting. The algorithm is trained with all training examples after picking the optimum parameter [19].

2.4 Sensitivity analysis

The susceptibility assessment is a basic process that assesses the system behaviors when a particular input is altered after the development operation. Let us accept the output produced by maintaining all input parameters at their average numbers X α , which change during the course of its full range ( X a , j , with j ϵ { 1,2 , , L } levels ). Variation ( V a ) of y α , j , as a measure of input significance, is employed. If N c > 2 (multiclass), the total of the deviations for each outcome class probability is calculated ( p ( C ) α , j ). A lot of variation ( V a ) shows a high level of X a as a result; the input’s proportional significance ( R a ) is

(4) R a = V a i = 1 I V i × 100 ( % ) .

The variable effect characteristic (VEC) curve has now been developed for a more precise examination, which depicts the X a , j characteristics (x-axis) against the y a , j projections (y-axis).

2.5 Measures of performance evolution

2.5.1 Classification accuracy (ACC)

The capacity of the algorithm to properly anticipate the class levels of new or previously unknown data is referred to as classification results. The proportion (percentage) of assessment collection samples successfully categorized by the classification is known as classification results. The accuracy level can be used to evaluate categorization performance. That is

(5) Accuracy ( T ) = i = 1 | T | assess ( t i ) | T | , t i T ,

(6) assess ( t ) = 1 if classify ( t ) = t . c 0 otherwise ,

such that T is the data set that must be categorized (the sample set in this case), t T , t . c seems to be the object’s category t , consequently classify ( t ) providing the categorization of t through the classification that was utilized (here, SVM and MLPE).

The performance development assessment in this section is mostly dependent on the classification results provided in equations (5) and (6). In addition, certain other performance indicators are examined. Following are some quick explanations of additional measurements [19].

2.5.2 AUC and ROC curve

AUC is a useful measure for evaluating classification model operations. When the value for categorizing an item as 0 or 1 is increased from 0 to 1, a plot of the TPR vs the false-positive rate is displayed. If the classification is really strong, the TPR will rapidly increase and the AUC will be close to 1. The AUC is useful for measuring detector performance on skewed data since it is independent of the percentage of the given population that falls into category 0 or 1. The AUC is useful for testing classifier performance on unbalanced data because of this attribute [19]. TPR (responsiveness) is determined as a function of the false-positive frequency at various ROC curve breaking points (100-specificity). Each position on the ROC curve indicates a sensitivity/responsiveness pair, or TPR/TNR, for a certain decision criterion.

The goal of this study was to determine the most accurate categorization and crucial input factors for MM disease identification. Tables 13 and Figures 35 present the results of applying DM methods. Table 1 shows that SVM and MLPE gave nearly identical results in all cases of efficiency development measurements. After 5 runs and 10-fold cross-validation, SVM has a classification performance of 99.87%, whereas MLPE NN has a classification performance of 99.56%. SVM produces 0.9999 for the AUC measure; however, MLPE returns 0.9998, which is substantially comparable to the SVM result. The remaining performance metrics follow a similar pattern of results. SVM obtained 99.8245 and 100% accuracy rates, whereas MLPE scored 99.5614 and 99.5416% true-positive and true-negative levels, respectively. Finally, the SVM value for the F1 score is 99.9560%, and the MLPE result is 99.6485% [20]. After examining the data in Table 1, it is evident that SVM is a more accurate classification than MLPE NN for all performance measures. Table 2 allows for the evaluation of the classification performance of SVM and MLPE run-wise findings. With a result of 99.87%, Table 3 demonstrates that SVM (with 10-fold cross-validation and 5-run architecture) achieved the best overall classification results. This is a great outcome for the diagnostic problem with MM’s condition. With a score of 99.56%, the MLPE NN (with 5 runs, 2 hidden layers, and 10-fold cross-validation) generated the second-best classification accuracy results. These two strategies make up all the methods discussed in this section. The third-best classification accuracy results were generated by AIS using only 10-fold cross-validation and no study repetitions. The PNN and MLNN are also effective in identifying MM illness diagnoses. The LIFT plot in Figure 3 illustrates a comparison of SVM and MLPE NN. Accordingly, the input important bar chart and VEC are displayed in the LIFT plot for the MM disease dataset’s MM sickness diagnosis utilizing SVM and MLPE NN. The input significance bar chart depicts the relative importance of each input variable to the response variable (measured as a score ranging from 0 to 1). For a more thorough analysis, a VEC plot is employed, which displays the most important input variable versus the response variations according to the x- and y-axis. The LIFT plot contrasts SVM with MLPE NN. Because each of these methods takes a similar amount away from the beginning position, the two lines are parallel. Both approaches extract roughly the same amount of data from the foundation, which is why the two lines are nearly identical. Figure 4 shows input significance bar graphs for 34 input parameters in the MM illness database. It yields some fascinating outcomes for this MM illness diagnostic issue. The most essential input parameter for diagnosing MM illness is ALP [21]. Figure 4 clearly shows that the parameter “City” is an essential element in prognosis. The patient’s situation is crucial in this situation. The parameter “City” file contains information further about the patient’s region. Asbestos exposure is generally known to be one of the leading causes of MM illness. So, it is crucial to know where the person comes from and if he or she has ever been exposed to mesothelioma [22]. Furthermore, Figure 5 shows the VEC plot for even the most external factors that are favorable, ALP. Patients with an ALP value of 300–500 have the best likelihood of developing MM illness.

3 Methodology

The research follows a quantitative approach to accomplish the research objectives. The objective of the current research is to identify the number of input variables of the disease MM that develop the maximum accuracy. Apart from this, the research also identifies the number of cross-validation folds and the number of runs at which the DM model gives the maximum accuracy. SVM will be used for feeding the input MM variables and the change in accuracy was evaluated through multiple regression analysis. One of the most crucial statistical methods used in analytical epidemiology is regression modeling. Regression models can be used to examine the impact of one or more explanatory factors (such as exposures, subject characteristics, or risk factors) on a response variable like mortality or cancer. Adjusted effect estimates that account for possible confounders can be derived using multiple regression models. Regression techniques are a fundamental tool for data analysis in epidemiology since they may be used in all types of epidemiologic research designs. Regression models of many types have been created depending on the study’s design and the measurement scale for the response variable. The most crucial techniques are logistic regression for binary outcomes, Cox regression for time-to-event data, Poisson regression for frequencies and rates, and linear regression for continuous outcomes. Statistical Package for Social Sciences (SPSS) by IBM was used for conducting the multiple regression analysis. An inductive research approach has been followed to interpret the research hypotheses. The hypotheses are

H0: The number of input MM variables does have a statistically significant relationship with the classification accuracy.

Cross-validation folds and the number of runs do not affect the classification accuracy of data mining when using SVM.

H1: Increasing the number of input MM variables increases the classification accuracy.

Cross-validation folds and the number of runs have a significant impact on the classification accuracy of data mining when using SVM.

In that context, the input independent variables for multiple regression analysis are (1) the number of input variables for SVM (MM disease); (2) cross-validation folds; and (3) the number of SVM runs. Concerning this, the dependent variable is the classification accuracy of DM using SVM.

4 Analysis and interpretation

SVM has been used with different numbers of folds and runs to evaluate the change in accuracy. To investigate the change in classification accuracy, multiple regression analysis was used. The results are tabulated in Table 4.

Table 4 shows the descriptive statistics output where it can be observed that a total of 15 experiments were performed and from them, 0 outputs are missing. Nevertheless, the mean number of input variables is 18.87, and corresponding with that, the classification accuracy was 97.1773%. It can be observed that a total of 34 input variables of MM diseases were fed to the SVM and a minimum of 2 variables were entered. Subsequently, the lowest classification accuracy was 92.35% and the highest accuracy was 99.68%. Besides, a complete 14 validation folds were used along with 8 runs (serially). However, the descriptive output cannot determine whether the independent variables are affecting the classification accuracy or not. Thus, the analyses in Table 5 demonstrate the multiple regression output.

Table 5 shows the coefficient variable at a 95% confidence level. The t-test value shows that a value of 0.201 has been observed between the “number of input variables” and the “classification accuracy of DM”. This shows that a smaller difference exists between the two variables. The significance value between these two variables has been observed at 0.844, which shows a low statistical significance (>0.05). A value of 1.095 has been observed between the variable “cross-validation folds” and “classification accuracy of DM”. This shows a greater difference exists between the two variables. The significance value of 0.302 shows a high statistical significance (<0.05). The difference value between “number of runs” and “classification accuracy of DM” has been observed at −0.315, which shows that very little difference and high similarities exist between the two variables. The significance value was observed at 0.758, which shows a low statistical significance (>0.05).

Table 6 shows the regression ANOVA analysis between the dependent and independent variables. The results have shown that a significance value of 0.000 has been observed, which shows a high statistical significance between the dependent and independent variables. The f statistical value has been observed at 34.822, which is a low value and indicates a low statistical significance.

Table 7 shows the model summary statistics and the results show that the R-value is 0.951 and the R square value has been observed at 0.905. This shows that a high R and R-square value has been observed between the dependent and independent variables and indicates a high statistical significance. The adjusted R square value has been observed at 0.879 and the estimated standard error has been observed at 0.81261, which indicates a statistically significant relationship between the independent and dependent variables.

Figure 6 shows the effective graphical representation between the variable “classification of DM accuracy” and “the number of cross-validation folds.” This shows that as the number of cross-validation folds increases the overall accuracy for DM efficiency increases. However, after some time the accuracy reaches a saturation point, and here as the cross-validation fold increases the accuracy of DM remains the same.

The regression analysis has shown that to effectively classify the malignant tissues, the increase in the number of inputs and the number of cross-validation folds are necessary as it helps in determining tissue culture analysis. The coefficient analysis at a 95% confidence level has shown that a statistically significant relationship exists between the cross-validation folds and the DM accuracy. Again, the graphical representations have shown that as the number of input variables increases, the overall accuracy for DM also increases.

Therefore, from the above data analysis, it can be stated that the accuracy level of MM classification depends on the number of input variables and the number of cross-validation folds. These data help researchers and healthcare professionals in successfully analyzing the accuracy level of MM classification. This is required for the proper diagnosis of malignant cells and helps in maintaining the patient’s well-being.

5 Conclusion

In this work, two alternative DM approaches for the MM illness diagnostic problem were used on an identical dataset. As demonstrated in this study, a person can be classified as having or not having MM illness. As per the final performance, the most stable and accurate DM approaches for categorizing MM data are SVM as well as MLPE NN architectures. It can be seen that a total of 15 tests were carried out, with 0 outputs missing. Nonetheless, the average number of input variables is 18.87, and the classification accuracy is 97.1773%. It can be seen that a total of 34 MM illness input variables were supplied to the SVM, with a minimum of 2 variables inputted. As a result, the lowest accuracy of the classification was 92.35% and the best classification accuracy was 99.68%. In addition, 14 validation folds and 8 runs were employed (serially). The regression analysis revealed that increasing the number of inputs and cross-validation folds is required to properly categorize malignant tissues, as it aids in deciding tissue culture analysis. The cross-validation folds and the DM efficiency are statistically related, according to the coefficient analysis at a 95% confidence level. In addition, the graphical displays have demonstrated that as the amount of input variables increases, so does the total accuracy for DM. Finally, ANN structures may be used as a learning-based DSS to aid physicians in making diagnoses. In addition, it is established from this study that the key input variables have a significant impact on virtually any illness diagnosis issue. All other ANN features were shown to be effective in assisting in the diagnosis of MM illness. Since only a few instances were incorrectly classified by the algorithm, this classification performance is quite trustworthy for such a situation. For the identification of MM illness, a ten-fold cross-validation approach with a repeating experimental procedure is more suited than any other traditional evaluation process. Finally, ANN frameworks may be used as a learning-based DSS to aid clinicians in making diagnosis judgments. Moreover, this study has revealed that crucial input components or variables have a significant impact on any form of illness diagnosing the problem. The most crucial input parameter for MM illness detection is ALP, according to this study. ALP is an excellent diagnostic in the event of liver illness, and an increased quantity of ALP in the patient’s psyche can induce cancer. Other characteristics that are crucial for MM disease rearrangement include city, chest pain, seniority, and gender of the client, according to scenario analysis and input significance bar chart. This section of the research might be extremely helpful to physicians in their assessment.
