Researchers have developed a novel triple spectral fusion framework for sensor-based human activity recognition (HAR). This framework addresses challenges in fusing heterogeneous sensor data and establishing long-term context correlations by employing adaptive filtering techniques across Fourier, graph Fourier, and wavelet domains. The approach includes noise suppression, modality node organization, and adaptive wavelet frequency selection to enhance feature extraction and context correlation, demonstrating superior performance on multiple benchmark datasets.
