Evaluation of Cluster Id Assignment Schemes with ABCDE
S van Staden - arXiv preprint arXiv:2409.18254, 2024 - arxiv.org
A cluster id assignment scheme labels each cluster of a clustering with a distinct id. The goal
of id assignment is semantic id stability, which means that, whenever possible, a cluster for …
