The Geometric Block Model
Sainyam Galhotra, Arya Mazumdar, Soumyabrata Pal +1
To capture the inherent geometric features of many community detection problems, we propose to use a new random graph model of communities that we call a Geometric Block Model. The…
Truly Sub-cubic Algorithms for Language Edit Distance and RNA Folding via Fast Bounded-Difference Min-Plus Product
Karl Bringmann, Fabrizio Grandoni, Barna Saha +1
It is a major open problem whether the -product of two matrices has a truly sub-cubic (i.e. for ) time algorithm, in particular since it is…
Query Complexity of Clustering with Side Information
Arya Mazumdar, Barna Saha
Suppose, we are given a set of elements to be clustered into (unknown) clusters, and an oracle/expert labeler that can interactively answer pair-wise queries of the form, "…
Clustering with Noisy Queries
Arya Mazumdar, Barna Saha
In this paper, we initiate a rigorous theoretical study of clustering with noisy queries (or a faulty oracle). Given a set of elements, our goal is to recover the true clusteri…
A Theoretical Analysis of First Heuristics of Crowdsourced Entity Resolution
Arya Mazumdar, Barna Saha
Entity resolution (ER) is the task of identifying all records in a database that refer to the same underlying entity, and are therefore duplicates of each other. Due to inherent am…
