This paper proposes OSPDIM, a source-free online unsupervised domain adaptation framework for EEG-based BCIs that corrects geometric misalignment caused by class-imbalanced label shifts on the Riemannian manifold, outperforming standard alignment methods in online scenarios.
This paper introduces SPACE, the first source-free unlearning framework for multimodal large language models (MLLMs), which uses text-guided proxy anchor selection and dual-constraint semantic isolation to erase target concepts without requiring access to original training data, achieving performance comparable to data-dependent methods.
