Approximating Star Cover Problems by Gamlath, Buddhima, Grinberg, Vadim

“…Given a metric space $(F \cup C, d)$, we consider star covers of $C$ with balanced loads. A star is a pair $(f, C_f)$ where $f \in F$ and $C_f \subseteq C$,…”

Nearly-Tight and Oblivious Algorithms for Explainable Clustering by Gamlath, Buddhima, Jia, Xinrui, Polak, Adam, Svensson, Ola

“…We study the problem of explainable clustering in the setting first formalized by Dasgupta, Frost, Moshkovitz, and Rashtchian (ICML 2020). A $k$-clustering is…”

Beating Greedy for Stochastic Bipartite Matching by Gamlath, Buddhima, Kale, Sagar, Svensson, Ola

“…We consider the maximum bipartite matching problem in stochastic settings, namely the query-commit and price-of-information models. In the query-commit model,…”

Semi-Supervised Algorithms for Approximately Optimal and Accurate Clustering by Gamlath, Buddhima, Huang, Sangxia, Svensson, Ola

“…We study $k$-means clustering in a semi-supervised setting. Given an oracle that returns whether two given points belong to the same cluster in a fixed optimal…”

Weighted Matchings via Unweighted Augmentations by Gamlath, Buddhima, Kale, Sagar, Mitrović, Slobodan, Svensson, Ola

“…We design a generic method for reducing the task of finding weighted matchings to that of finding short augmenting paths in unweighted graphs. This method…”
