What's Happening?
A new deep learning framework, CrossMod-Transformer, has been developed to enhance pain detection through the fusion of electrodermal activity (EDA) and electrocardiography (ECG) data. The framework utilizes a hierarchical fusion mechanism combining fully convolutional networks (FCN), attention-based long short-term memory (ALSTM) networks, and Transformers. This design allows the model to capture complex patterns in time-series data, improving the accuracy of pain recognition. The study employs the BioVid Heat Pain Database and AI4PAIN dataset for evaluation, demonstrating the framework's ability to integrate uni-modal and multi-modal features effectively.
