Dynamics-Guided Cross-Modality Masked State Space Modeling for Robust Wearable Human Activity Recognition

Wearable sensor-based Human Activity Recognition (HAR) is important for continuous health monitoring, assistive systems, and context-aware systems. Despite recent progress, real-world deployment remains difficult due to issues such as sensor noise, missing data, device heterogeneity, and limited annotated samples. Alth...
