Prior work primarily formulates Context-Aware Human Activity Recognition (CA-HAR) as a multi-label classification problem.Existing CA-HAR methods struggle to capture the semantic relationships between activity labels, limiting their accuracy.To address this limitation, researchers propose SEAL, which leverages Language Models (LMs) to encode CA-HAR activity labels.SEAL uses LMs to generate vector embeddings that preserve rich semantic information from natural language, improving CA-HAR accuracy.
