Greedy layer-wise training of dbn
WebJan 9, 2024 · The greedy layer-wise training algorithm for DBN is very simple as given below Train a DBN in a entirely unsupervised way with the greedy layer-wise process where every added layer is trained like an RBM by CD. In second step of the DBN, the parameters are fine-tuned over all the layers cooperatively.
