Recovering Planted Subgraphs

Series: CSA Faculty Colloquium

Speaker: Prof. Anand Louis, Associate Professor Dept. of CSA

Date/Time: Sep 06 16:00:00

Location: CSA auditorium [Room No. 104], ground floor

Abstract:
Recovering a subgraph with a specified property hidden in a random graph is a fundamental problem in the study of algorithms. One of the central problems in this direction of study is the planted clique problem, where a clique is planted in an Erdos-Renyi random graph. The seminal work of Alon, Krivelevich and Sudakov (1998) gave an algorithm to compute planted cliques of size ?(??{n}); their algorithm was based on using the graphs spectra. This work has inspired numerous works on this and related problems using tools from random matrix theory, random graphs, -sum-of-squares- framework, convex optimization, and machine learning. I will survey the history and some recent developments related to this problem including some of our recent work.
