Co-Dream: Collaborative Dream Synthesis over Decentralized Models

Abhishek Singh, Gauri Gupta, Yichuan Shi, Alex Dang, Ritvik Kapila, Sheshank Shankar +2
AAAI 2025technical

Federated Learning (FL) has pioneered the idea of "share wisdom not raw data" to enable collaborative learning over decentralized data. FL achieves this goal by averaging model parameters instead of centralizing data. However, representing "wisdom" in the form of model parameters has its own limitat…

ZeroHAR: Sensor Context Augments Zero-Shot Wearable Action Recognition

Ranak Roy Chowdhury, Ritvik Kapila, Ameya Panse, Xiyuan Zhang, Diyan Teng, Rashmi Kulkarni +3
AAAI 2025technical

Wearable Human Action Recognition (wHAR) uses motion sensor data to identify human movements, which is essential for mobile and wearable devices. However, traditional wHAR systems are only trained on a limited set of activities. Hence, they fail to generalize to diverse human motions, prompting Zero…
