AWhat changed
Introduced a wake–sleep learning procedure that alternately adapts bottom-up recognition connections and top-down generative connections in multilayer neural networks.
Scientific scope
The record is the exact 1995 Science paper. Helmholtz-machine framing, later variational inference, variational autoencoders and subsequent generative-model training methods remain separate.
Evidence
The linked sources identify this contribution and its scope. WRS has not independently reconstructed the scientific claims. The record is the exact 1995 Science paper. Helmholtz-machine framing, later variational inference, variational autoencoders and subsequent generative-model training methods remain separate.
