Perturbative Contrastive Physical Learning
Researchers have introduced Perturbative Contrastive Physical Learning (PCPL), a new framework where learning arises from contrasting how physical systems respond to slight variations. This approach unifies and extends existing methods like Equilibrium Propagation and Frequency Propagation. PCPL allows learning without centralized gradient computation, as the learning geometry emerges implicitly from the system's physical response. AI
