Overview

Benchmarking analysis demonstrates enhanced clustering accuracy and efficiency on complex and variable-density datasets, highlighting improved reliability for granular-ball density clustering.

Key Points

To develop an adaptive, multi-factor granular ball-based density clustering algorithm (MFGB-DBSCAN) that resolves parameter sensitivity, boundary ambiguity, and high computational costs.
Designed adaptive parameter initialization using data distribution metrics to determine neighborhood and connection scales.
Integrated a quality-driven evaluation and multi-factor fusion strategy combining density, cohesion, separation, spatial proximity, and geometric overlap to build cluster skeletons.
Implemented a confidence-based two-stage label propagation method to accurately refine boundary point assignments on synthetic and real-world benchmark datasets.
Demonstrated competitive clustering accuracy and computational speed compared to representative baseline algorithms.
Showed robust performance in handling datasets with complex geometric structures and varying density distributions.
