New training method for physical neural networks unveiled

Researchers have developed a new training method called Near-Equilibrium Propagation (NEP) that extends Equilibrium Propagation (EP) for use in complex-valued wave systems. This novel approach is effective even in weakly dissipative regimes and allows for in-situ training by adjusting local parameters, rather than requiring direct control over inter-node connections. The method was successfully tested on benchmarks for logical tasks and handwritten-digit recognition, demonstrating stable convergence and offering a practical pathway for training physical systems with limited control.
