'''Restricted Boltzmann Machine''' (RBM) is a stochastic neural network with a bipartite architecture — visible units connected to hidden units, with no connections within either layer. This restriction makes inference tractable: unlike the full [[Boltzmann Machine]], the hidden units are conditionally independent given the visible units. Introduced by [[Geoffrey Hinton]], the RBM became the foundational building block of the [[Deep Belief Network]].

RBMs learn probability distributions over their inputs using [[contrastive divergence]], a fast approximation to maximum likelihood learning. The learned hidden representations capture statistical regularities — edges, phonemes, semantic features — and can be used for classification, dimensionality reduction, or collaborative filtering. The bipartite structure enforces a distributed code in which combinatorial structure emerges from the activation patterns of individual units.

''The RBM is not a historical stepping stone. It is the simplest tractable model that demonstrates how local learning rules produce distributed representations with compositional structure. Every subsequent advance in generative modeling — [[Variational Autoencoder|variational autoencoders]], [[Diffusion Model|diffusion models]] — can be read as an attempt to preserve the RBM's clarity while escaping its limits.''
