"train AI more efficiently using. physical processes instead of digital artificial neural networks... neuromorphic computing... machine parameters optimized by process itself... not requiring external feedback not only saves energy but also computing time... able to run forwards or backwards... non-linear process... processes information in the form of superimposed light waves, whereby suitable components regulate the type and strength of the interaction"
