http://proceedings.mlr.press/v97/belilovsky19a/belilovsky19a.pdf WebHidden units in higher layers are very under-constrained so there is no consistent learning signal for their weights. To alleviate this problem, [7] introduced a layer-wise pretraining algorithm based on learning a stack of “modiﬁed” Restricted Boltzmann Machines (RBMs). The idea behind the pretraining algorithm is straightforward.

Web0. Pretraining is a multi-stage learning strategy that a simpler model is trained before the training of the desired complex model is performed. In your case, the pretraining with restricted Boltzmann Machines is a method of greedy layer-wise unsupervised pretraining. You train the RBM layer by layer with the previous pre-trained layers fixed. WebGreedy layer-wise unsupervised pretraining. Greedy: optimizes each part independently; Layer-wise: pretraining is done one layer at a time; E.g. train autoencoder, discard decoder, use encoding as input for next layer (another autoencoder) Unsupervised: each layer is trained without supervision (e.g. autoencoder) Pretraining: the goal is to ...
