Fair algorithms for clustering
We study the problem of finding low-cost {\em fair clusterings} in data where each data point
may belong to many protected groups. Our work significantly generalizes the seminal work …

On the cost of essentially fair clusterings
Clustering is a fundamental tool in data mining. It partitions points into groups (clusters) and
may be used to make decisions for each point based on its group. However, this process …

Optimal Fully Dynamic k-Center Clustering for Adaptive and Oblivious Adversaries
In fully dynamic clustering problems, a clustering of a given data set in a metric space must
be maintained while it is modified through insertions and deletions of individual points. In …

Tight FPT approximation for constrained k-center and k-supplier
In this work, we study a range of constrained versions of the k-supplier and k-center
problems. In the classical (unconstrained) k-supplier problem, we are given a set of clients C …

Selecting the independent coordinates of manifolds with large aspect ratios
Many manifold embedding algorithms fail apparently when the data manifold has a large
aspect ratio (such as a long, thin strip). Here, we formulate success and failure in terms of …
