Research & Tech Development
Oscillator Processing Unit
Oscillators are physical systems that are capable of complex dynamics. Through the architecture of physical reservoir computing, these complex dynamics can be repurposed as a computational resource. Effectively, the oscillator is an analog neural network, which can be retrained for different tasks.
An example of this is on the right, in which a van der Pol (vdP) oscillator acts as a reservoir. Some selected publications are provided below.
Scientific R&D of the OPU is interdisciplinary, involving physics, mathematics, mechanical engineering, and electrical engineering.
