Today, in NeurONN Lecture Series, we welcome Prof. Chris H. Kim, University of Minnesota. His talk will be on coupled oscillator based computing – using nature to solve difficult problems.
Title: Coupled Oscillator based Computing – Using Nature to Solve Difficult Problems

Abstract: In this talk, I will introduce a computing paradigm that exploits the natural tendency of a network of coupled oscillators to settle to the ground state. Our first-of-its kind test chip with almost 2,000 coupled oscillators implemented in a standard 65nm technology shows that solutions to NP-hard problems such as max-cut can be found with higher efficiency than traditional digital computation. Extensive testing shows that coupled oscillators can probabilistically explore the energy landscape to find a good minima point. This has implications on a wide range of intractable problems that can be mapped to a quadratic unconstrained binary cost function.
