New clustering method uses anomaly detection and minimal seeds

Researchers have developed a novel semi-supervised clustering framework that leverages the statistical duality between grouping principles and anomaly detection. This method, called "clustering-by-exclusion," uses a Perception algorithm with an expectation-based threshold to identify outliers without manual parameter tuning. By employing minimal user-provided seeds, the algorithm iteratively refines clusters, effectively isolating noise and identifying new clusters, and has shown competitive performance on various benchmarks. AI
