Oscillating Neural Networks

Performing pattern recognition and solving complex optimization problems with coupled oscillator networks.

Overview

Combinatorial optimization problems find applicability in multiple industrial applications, such as drug synthesis, resource allocation, AI, computer vision, and circuit design. Solving these problems poses a persistent challenge for computer scientists today, as even the most advanced chips performance falls short compared to the capabilities of the human brain. We explore novel computing approaches emulating the brain's operations to solve optimization problems with high-power efficiency. We design oscillating neural networks driven by nanoscale switches harnessing vanadium dioxide's metal-insulator transition. Through rigorous device testing and circuit simulations, we power applications in neuromorphic computing and machine learning, bringing a touch of nature-inspired innovation to modern technology.
