Efficient Source-Free Time-Series Adaptation via Parameter Subspace Disentanglement

Gaurav Patel, Christopher Sandino, Behrooz Mahasseni +4

In this paper, we propose a framework for efficient Source-Free Domain Adaptation (SFDA) in the context of time-series, focusing on enhancing both parameter efficiency and data-sam…
