TxP: Reciprocal Generation of Ground Pressure Dynamics and Activity Descriptions for Improving Human Activity Recognition
A bidirectional text-pressure model with a learned codebook generates synthetic pressure data from activity descriptions and classifies real pressure sequences via LLM-generated text, gaining up to 12.4 macro-F1 points on one benchmark but losing on sleeping-posture data.
