PHIDA: Persistence-Guided Node-to-Cluster Mapping for Online Clustering

ArXi:2605.08673v1 Announce Type: new Online clustering methods that adaptively create and update nodes as data arrive often make node learning explicit, whereas the mapping from the learned node state to output clusters often remains implicit or simplified. Implicit mappings make output clusters sensitive to weak graph bridges or local relations based on distance in the graph over learned nodes, leaving no explicit constraint on which node groups remain intact during mapping.
