研究人员对层次聚类目标函数提出了新的理论见解。他们在特定的多项式条件下表征了可容许的求和型目标函数，并提出了一类新的最大值型目标函数。对于这些最大值型函数，他们建立了可容许性的通用且完整的表征，特别是在缩放函数是次数最多为二的对称多项式时。 AI
影响 为聚类算法提供了新的理论基础，可能影响数据分析和机器学习流程。

分层聚类的可容许目标函数的表征
arXiv:2604.23628v1 Announce Type: cross Abstract: Hierarchical clustering is a fundamental task in data analysis, yet for a long time it lacked a principled objective function. Dasgupta [STOC 2016] initiated a formal framework by introducing a discrete objective function for clus…
