On the Parameterized Approximability of (Mergeable) Sum of Radii Clustering

Ameet Gadekar

The sum of radii problem (-MSR) asks, given a metric space on points, to place balls covering all points so as to minimize the sum of their radii. Despite extensive stud…

FPT Approximations for Fair Sum of Radii with Outliers and General Norm Objectives

Ameet Gadekar

The sum of radii problem is a classical clustering problem in which, given a set of points and an integer , the goal is to place balls that cover while minimizing th…

Fair Committee Selection under Ordinal Preferences and Limited Cardinal Information

Ameet Gadekar, Aristides Gionis, Suhas Thejaswi +1

We study the problem of fair -committee selection under an egalitarian objective. Given agents partitioned into groups (\eg, demographic quotas), the goal is to aggregat…

Label-consistent clustering for evolving data

Ameet Gadekar, Aristides Gionis, Thibault Marette

Data analysis often involves an iterative process, where solutions must be continuously refined in response to new data. Typically, as new data becomes available, an existing solut…

Capacitated Fair-Range Clustering: Hardness and Approximation Algorithms

Ameet Gadekar, Suhas Thejaswi

Capacitated fair-range -clustering generalizes classical -clustering by incorporating both capacity constraints and demographic fairness. In this setting, each facility has a…

Clustering under Constraints: Efficient Parameterized Approximation Schemes

Sujoy Bhore, Ameet Gadekar, Tanmay Inamdar

We present a unified framework that yields EPASes for constrained -clustering in metric spaces of bounded (algorithmic) scatter dimension, a notion introduced by Abbasi et a…

Dimension-Free Parameterized Approximation Schemes for Hybrid Clustering

Ameet Gadekar, Tanmay Inamdar

Hybrid -Clustering is a model of clustering that generalizes two of the most widely studied clustering objectives: -Center and -Median. In this model, given a set of p…

Fair Clustering for Data Summarization: Improved Approximation Algorithms and Complexity Insights

Ameet Gadekar, Aristides Gionis, Suhas Thejaswi

Data summarization tasks are often modeled as -clustering problems, where the goal is to choose data points, called cluster centers, that best represent the dataset by minim…

FPT approximations for Capacitated Sum of Radii and Diameters

Arnold Filtser, Ameet Gadekar

The Capacitated Sum of Radii problem involves partitioning a set of points , where each point has capacity , into clusters that minimize the sum of cluster rad…

Diversity-aware clustering: Computational Complexity and Approximation Algorithms

Suhas Thejaswi, Ameet Gadekar, Bruno Ordozgoiti +1

In this work, we study diversity-aware clustering problems where the data points are associated with multiple attributes resulting in intersecting groups. A clustering solution nee…

Independent set in -Claw-Free Graphs: Conditional -boundedness and the Power of LP/SDP Relaxations

Parinya Chalermsook, Ameet Gadekar, Kamyar Khodamoradi +1

This paper studies -claw-free graphs, exploring the connection between an extremal combinatorics question and the power of a convex program in approximating the maximum-weight i…

Parameterized Approximation for Robust Clustering in Discrete Geometric Spaces

Fateme Abbasi, Sandip Banerjee, Jarosław Byrka +6

We consider the well-studied Robust -Clustering problem, which generalizes the classic -Median, -Means, and -Center problems. Given a constant , the input…

Clustering with fair-center representation: parameterized approximation algorithms and heuristics

Suhas Thejaswi, Ameet Gadekar, Bruno Ordozgoiti +1

We study a variant of classical clustering formulations in the context of algorithmic fairness, known as diversity-aware clustering. In this variant we are given a collection of fa…

On the parameterized complexity of Compact Set Packing

Ameet Gadekar

The Set Packing problem is, given a collection of sets over a ground set , to find a maximum collection of sets that are pairwise disjoint. The problem i…

On learning k-parities with and without noise

Arnab Bhattacharyya, Ameet Gadekar, Ninad Rajgopal

We first consider the problem of learning -parities in the on-line mistake-bound model: given a hidden vector with and a sequence of "questions" $a_1,…
