我们介绍了(p,q)-公平聚类问题。在这个问题中,我们给出一组点P和一组不同的权函数W。我们希望找到一个聚类,它最小化W上的向量的范数和P中的点到中心的加权距离的范数。这推广了各种聚类问题,包括社会公平中值和k均值,并密切联系到其他问题,如Densestk-子图和Mink-联盟。我们利用凸规划技术来近似(p,q)-公平聚类问题的不同值的pandq。当p ≥q时,基于Mink-Union的严格性和其它问题,我们得到了一个O(k(p-q)/(2 pq)),它几乎匹配akΩ((p-q)/(pq))下界.当q ≥p时,我们得到了一个近似,它与boundedp,q的输入大小无关,并且与Makarychev和Vakilian(COLT 2021)的(p,∞)-Fair Clustering的recentO((logn/(log logn))1/p)-近似相匹配。
We introduce the (p, q)-Fair Clustering problem. In this problem, we are given a set of pointsPand a collection of different weight functionsW. We would like to find a clustering which minimizes theℓq-norm of the vector overWof theℓp-norms of the weighted distances of points inPfrom the centers. This generalizes various clustering problems, including Socially Fairk-Median andk-Means, and is closely connected to other problems such as Densestk-Subgraph and Mink-Union.We utilize convex programming techniques to approximate the (p, q)-Fair Clustering problem for different values ofpandq. Whenp≥q, we get anO(k(p–q)/(2pq)), which nearly matches akΩ((p–q)/(pq))lower bound based on conjectured hardness of Mink-Union and other problems. Whenq≥p, we get an approximation which is independent of the size of the input for boundedp,q, and also matches the recentO((logn/(log logn))1/p)-approximation for (p, ∞)-Fair Clustering by Makarychev and Vakilian (COLT 2021).
