An explainable multimodal deep learning approach for stress detection in emotion-aware systems

Abstract We propose a continuous stress-detection pipeline that integrates wavelet-based heart-rate-variability (HRV) features with behavioural signals in a staged ensemble. The method computes time-resolved HRV spectral indices (VLF/LF/HF) using wavelet decomposition and incorporates them with beha...
