Researchers have introduced a new theoretical framework that links information theory, topology, and statistical mechanics to understand the limits of learnability in deep neural networks. This framework defines an Entropic Learnability Horizon (ELH), a fundamental law stating that a network can only learn a target function if its data manifold's Shannon entropy surpasses the topological entropy of the function's decision boundary, modulated by the network's weight space entropy. When a target boundary's complexity exceeds this informational horizon, the system enters a state of "Informational Frustration," where generalization becomes impossible. The paper also proposes Entropic Gradient Descent (EGD) as an optimization algorithm to manage weight entropy and facilitate learning. AI
