Neuron Statistics: Notes on the Tensor Programs Master Theorem

Tensor programs are a mathematical framework for understanding neural networks. According to LessWrong, the tensor programs master theorem shows how as neural networks get wider, the behavior of individual neurons becomes predictable through a simpler mathematical model. This provides rigorous foundations for studying phenomena like Gaussian-process limits and neural tangent kernels. The detailed explanation addresses a technical challenge: when weight matrices are reused through backpropagation, correlations emerge that can't be treated as independent noise. While this is highly technical material for researchers, it offers fundamental theory for understanding how large neural networks behave.
