Open Continual Feature Selection via Granular-Ball Knowledge Transfer

no code implementations15 Mar 2024 Xuemei Cao, Xin Yang, Shuyin Xia, Guoyin Wang, Tianrui Li

To this end, the proposed CFS method combines the strengths of continual learning (CL) with granular-ball computing (GBC), which focuses on constructing a granular-ball knowledge base to detect unknown classes and facilitate the transfer of previously learned knowledge for further feature selection.
