Researchers have developed a Landau-type theory to better understand invariant learning, a method focused on creating representations that remain predictive across different environments. This new theory models representation learning as a form of multimode magnetization, deriving an effective free energy from invariant-learning objectives. The theory's coefficients predict distinct regularization phenotypes, explaining how models learn as regularization strength changes, and have been validated through experiments on ReLU networks. AI
