Researchers have developed a novel multimodal learning framework to improve the detection of electrical arcing events in pantograph-catenary systems. This approach combines high-resolution image data with force measurements to enhance accuracy and robustness, addressing challenges like transient events and data scarcity. The framework, named MultiDeepSAD, is an extension of the DeepSAD algorithm and incorporates tailored pseudo-anomaly generation techniques for both visual and force data. Experiments show that this method significantly outperforms existing approaches, even when faced with domain shifts and limited real-world arcing observations. AI
