Lecture Title: Knowledge-Induced Multi-Kernel Fuzzy Clustering

Lecturer: Professor Tang Yiming

Affiliation: Hefei University of Technology

Lecture Time: October 21, 2023 (Saturday) 14:30-18:00

Lecture Location: Room 1106, Science and Education Building A, Emerald Lake Campus

Lecture Abstract:

The introduction of domain knowledge has opened up a new field for fuzzy clustering, resulting in knowledge-driven and data-driven fuzzy clustering methods. To solve the problems of imperfect extraction mechanism and imperfect fusion mode in these methods, we propose a Knowledge-Induced Multi-Kernel Fuzzy Clustering (KMKFC) algorithm. Firstly, to better extract knowledge points, a Relative Density-based Knowledge Extraction (RDKE) method is proposed to extract high-density knowledge points close to the cluster centers of the real data structure and provide initial cluster centers; the introduction of a multi-kernel mechanism maps data to high-dimensional space, which can improve the adaptability of the clustering algorithm, better discover the differences between data, and obtain better clustering results. Secondly, the knowledge points generated by RDKE are integrated into KMKFC through the knowledge influence matrix, guiding the iterative process of KMKFC. Again, a strategy for automatically obtaining knowledge points is proposed, including the RDKE Automatic Knowledge Acquisition method (RDKE-A) and the corresponding KMKFC-A algorithm. The convergence of KMKFC and KMKFC-A is proved. Finally, experimental research shows that KMKFC and KMKFC-A algorithms are superior to related comparison algorithms in multiple evaluation indicators and convergence speed.
