What changed
Introduced contrastive divergence as a tractable approximate learning objective and demonstrated product-of-experts training.
Scientific scope
The record is Hinton's sole-author 2002 paper and its product-of-experts experiments. Contrastive divergence is an approximation, not exact maximum-likelihood training or a convergence guarantee for every energy-based model.
