Polynomial-Time Constant-Approximation for Fair Sum-of-Radii Clustering

Sina Bagheri Nezhad, Sayan Bandyapadhyay, Tianzhi Chen

In a seminal work, Chierichetti et al. introduced the -fair clustering problem: Given a set of red points and a set of blue points in a metric space, a clustering is called…

Robust Contraction Decomposition for Minor-Free Graphs and its Applications

Sayan Bandyapadhyay, William Lochet, Daniel Lokshtanov +6

We prove a robust contraction decomposition theorem for -minor-free graphs, which states that given an -minor-free graph and an integer , one can partition in polynomi…

Extraction Theorems With Small Extraction Numbers

Arjun Agarwal, Sayan Bandyapadhyay

In this work, we develop Extraction Theorems for classes of geometric objects with small extraction numbers. These classes include intervals, axis-parallel segments, axis-parallel…

Fair Summarization: Bridging Quality and Diversity in Extractive Summaries

Sina Bagheri Nezhad, Sayan Bandyapadhyay, Ameeta Agrawal

Fairness in multi-document summarization of user-generated content remains a critical challenge in natural language processing (NLP). Existing summarization methods often fail to e…

A Polynomial-Time Approximation for Pairwise Fair -Median Clustering

Sayan Bandyapadhyay, Eden Chlamtáč, Zachary Friggstad +3

In this work, we study pairwise fair clustering with groups, where for every cluster and every group , the number of points in from group mus…

An -Time Approximation Scheme for Geometric Many-to-Many Matching

Sayan Bandyapadhyay, Jie Xue

Geometric matching is an important topic in computational geometry and has been extensively studied over decades. In this paper, we study a geometric-matching problem, known as geo…
