Summary

A new parameter-free adaptive resonance theory (ART)-based topological clustering algorithm has been developed, addressing the critical impact of similarity and edge deletion thresholds on clustering performance. This algorithm integrates methods for estimating both thresholds: the similarity threshold is determined using a determinantal point process-based criterion, while the edge deletion threshold is defined by the age of the edges. The proposed method, initially submitted on May 1, 2023, and last revised on February 19, 2026 (v3), demonstrates superior clustering performance compared to existing algorithms on both synthetic and real-world datasets. A key advantage is its ability to operate effectively without requiring dataset-specific parameter specifications, simplifying its application across diverse data. Source code for the algorithm is publicly available.

Key takeaway

For research scientists developing or deploying clustering solutions, this parameter-free ART-based algorithm offers a significant advantage by eliminating the need for manual parameter tuning. You should consider integrating this approach into systems requiring robust, adaptive clustering across varied datasets, especially where continual learning is essential. This could streamline development and improve performance.
