- Abstract:
-
The Takagi-Sugeno-Kang (TSK) fuzzy classifier (FC) has been widely applied to various fields owing to its excellent classification performance and interpretability. To address the degradation of the generalization performance of this TSK TSK FC caused by the differences in the distributions of the training and test samples, a domain adaptive (DA) pseudo-label refinement (PLR)-based TSK FC (DA-TSK-PLR-FC) is proposed. This classifier leverages the nonlinear and linear mapping capabilities of the antecedent and consequent parts in fuzzy rules to construct a fuzzy shared feature space for source and target domain data. In this fuzzy shared feature space, graph-based random walking and label filtering refinement were applied to enhance the pseudo-label quality in the target domain, thereby enhancing the effectiveness of the domain alignment. Further, extensive experiments using multiple public datasets reveal that the proposed DA-TSK-PLR-FC achieves reliable classification performance and good interpretability.
