Abstract
The present disclosure discloses a cross-session brainprint recognition method based on a tensorized spatial-frequency attention network (TSFAN) with domain adaptation. For most of existing multi-source domain adaptation methods, domain gaps between multiple source domains and target domains are individually bridged, but a relationship between domain-invariant features in distribution alignment is ignored. The present disclosure assists performance of a target domain by modeling an important relationship of the domain-invariant features without being affected by a distribution difference between source domains. A new TSFAN is used to combine pairwise source and target and an appropriate common spatial-frequency feature across source domains. Considering of a dimension, the TSFAN is further approximated as a low-rank Tucker format, to enable the TSFAN to adapt to scale linearly in a quantity of domains, and apply the TSFAN to a case of any quantity of sessions.
