Title: Coded Computing

 

Abstract: 

 

This talk introduces "Coded Computing”, a new framework that brings concepts and tools from information theory and coding theory into distributed computing to mitigate several performance bottlenecks that arise in large-scale machine learning. It is demonstrated how coded computing achieves the optimal tradeoff between “communication load” and “computation load” in distributed computing, and how it provides an optimal toleration for straggling nodes by injecting computation redundancy in unorthodox coded forms. The practical impact of coded computing is also demonstrated in several applications. The talk will conclude by discussing several open problems in this area.
