Universal Domain Adaptation (UniDA) aims to transfer knowledge from a labeled source domain to an unlabeled target domain, even when their classes are not fully shared.
Few dedicated UniDA methods exist for Time Series (TS), which remains a challenging case.
The paper introduces UniJDOT, an optimal-transport-based method that accounts for the unknown target samples in the transport cost.
Experiments on TS benchmarks demonstrate the discriminability, robustness, and state-of-the-art performance of UniJDOT.
