Chhavi Sharma, Ph.D. student of IEOR, presented her work (co-authored with Prof Vishnu Narayanan and Prof. P. Balamurugan) on Switch and Conquer: Efficient Algorithms By Switching Stochastic Gradient Oracles For Decentralized Saddle Point Problems at IEEE conference on Decision and Control (CDC) 2023 held at Marina Bay Sands, Singapore from 13-15 Dec 2023. Her work dived deeper into the behaviour of stochastic variance reduced gradient oracle in inexact primal dual hybrid gradient method for solving saddle point problems in the decentralized environment. This work has designed an algorithm that facilitates an effective switch between general stochastic gradient oracle and stochastic variance reduced gradient oracle, aiming to enhance the performance of the primal dual hybrid gradient method.
CDC brings experts in systems, control and decision science with the objective of disseminating new research results and fostering collaboration in these fields. The conference featured a variety of workshops, presentations and chances to network with researchers across the globe.
