Gravity-Aware Hierarchical Routing for Lightweight SensorLLM on Human Activity Recognition
Researchers propose a gravity-aware hierarchical routing method to improve human activity recognition in compressed language models used with wearable sensors. The lightweight adaptation addresses a specific failure mode where static activities like standing and sitting are poorly recognized when using compact models like TinyLlama, while maintaining strong performance on dynamic activities.
