New framework bounds information acquisition in neural networks

Researchers have developed a new framework to understand how neural networks acquire information during the learning process. By modeling stochastic gradient descent (SGD) as a Markovian stochastic process, they derived a Fisher-information flow speed limit. This limit quantifies how quickly trainable parameters can learn about latent variables in the data, separating the contributions of deterministic learning forces and SGD-induced fluctuations. The framework was validated using basis-function linear regression, accurately predicting the encoding timescales of different latent variables. AI
