Physical learning models analyzed for gradient flow and rotational dynamics

A new research paper explores the concept of physical learning, where trainable materials or networks use their physical responses to propagate error signals, thus reducing the need for explicit backward computation. The study focuses on directed layered transport networks, demonstrating how conservation laws constrain learning directions. The paper introduces the idea that reciprocity in the response leads to a reweighted gradient flow, while an antisymmetric boundary component can introduce rotational learning paths. Numerical consistency checks confirm these findings and highlight how trajectory drift can impact the effectiveness of learning. AI
