Sublinear Metric Steiner Forest via Maximal Independent Set
Sepideh Mahabadi, Mohammad Roghani, Jakub Tarnawski +1
In this work we consider the Metric Steiner Forest problem in the sublinear time model. Given a set of points in a metric space where distances are provided by means of que…
The Expiration Streaming Model: Diameter, -Center, Counting, Sampling, and Friends
Lotte Blank, Sergio Cabello, MohammadTaghi Hajiaghayi +5
An important thread in the study of data-stream algorithms focuses on settings where stream items are active only for a limited time. We introduce a new expiration model, where eac…
A 0.51-Approximation of Maximum Matching in Sublinear Time
Sepideh Mahabadi, Mohammad Roghani, Jakub Tarnawski
We study the problem of estimating the size of a maximum matching in sublinear time. The problem has been studied extensively in the literature and various algorithms and lower bou…
Guessing Efficiently for Constrained Subspace Approximation
Aditya Bhaskara, Sepideh Mahabadi, Madhusudhan Reddy Pittu +2
In this paper we study constrained subspace approximation problem. Given a set of points in , the goal of the {\em subspace approximation} pr…
Streaming Algorithms for Network Design
Chandra Chekuri, Rhea Jain, Sepideh Mahabadi +1
We consider the Survivable Network Design problem (SNDP) in the single-pass insertion-only streaming model. The input to SNDP is an edge-weighted graph and an integer…
Graph-Based Algorithms for Diverse Similarity Search
Piyush Anand, Piotr Indyk, Ravishankar Krishnaswamy +4
Nearest neighbor search is a fundamental data structure problem with many applications in machine learning, computer vision, recommendation systems and other fields. Although the m…
