Excited to share that our paper "ZeroHAR: Sensor Context Augments Zero-Shot Wearable Action Recognition" got accepted at AAAI 2025 (Main Technical Track)! Traditional wearable Human Activity Recognition (wHAR) systems fail to generalize to diverse human motions. Existing Zero Shot Learning methods for wHAR focus solely on augmenting labels, such as representing them as attribute matrices, images, videos, or text. We propose our ZeroHAR model architecture, that enhances time-series zero-shot learning for Human Activity Recognition by augmenting motion data with spatial and bio-mechanical sensor context features. We propose a two-stage training framework for ZSL on Wearable HAR: integrating human activity time-series data with sensor context, followed by activity recognition. Our model is generalizable across diverse human motions, with 262% improvement in zero-shot accuracy across 18 benchmark HAR datasets. Huge thanks to my brilliant co-authors Ranak Roy Chowdhury, Ameya Panse, Xiyuan Zhang, Diyan Teng, Rashmi Kulkarni, Dezhi Hong, Professor Rajesh Gupta and Prof. Jingbo Shang for their invaluable contribution and support. #AAAI2025 #MachineLearning #WearableTechnology #HumanActionRecognition #HAR
