Abstract

The use of multimodal datamultimodal data has been revealed to be a paradigm shift within and across different fields for anomalous behavior diagnosis, with improved performance and standard measures of returns on investment. Precisely, this book chapter offers a systematic literature review of studies on multimodal anomaly detection, as well as the techniques used in the different phases of the MDL process acquisition, preprocessing, feature extraction, modeling, and evaluation based on the proposed taxonomy, consequently, highlighting the applications and challenges in industrial, medical, and real-time settings. It also covers state-of-the-art approaches, including feature-level fusion, decision-level fusion, and model-level fusion, the use of deep learning, and graph-based methods. The chapter focuses on the examples of using these techniques in practice, showing how automotive manufacturing, aerospace maintenance, semiconductor production, and medical imaging industries can benefit from them. Some of the main issues like the scalability in big data, data integration, and real-time processing are solved with modern solutions, and future perspectives are shown. Thus, this chapter is most relevant for researchers and practitioners who look for means to enhance accuracy and ROI of the anomaly detection via multimodal analysismultimodal analysis.
