In relation to RBM, Contrastive Divergence(CD) is a method for approximation of the gradients of the log-likelihood(Hinton, G. E. 2002). Like Shape-BM, Convolutional Auto-Encoder differs from Stacked Auto-Encoder as their weights are shared among all locations in the input, preserving spatial locality. The following sections will begin by introducing the theory behind an RBM, including … - Selection from Advanced Machine Learning with Python [Book] Lyu, Q., Wu, Z., Zhu, J., & Meng, H. (2015, June). Semi-supervised learning with ladder networks. # Controller of Convolutional Auto-Encoder, pydbm.cnn.convolutionalneuralnetwork.convolutional_auto_encoder. auto-encoder, (2016, June). If LSTMModels are delegated, the shape of feature_points_arr is rank-3 array-like or sparse matrix: (The number of samples, The length of cycle, The number of units in hidden layers). Other than that, RBMs are exactly the same as Boltzmann machines. # If approximation is the Contrastive Divergence, this parameter is `k` in CD method. Working of Restricted Boltzmann Machine. 654-660). Still, there seems to be some interest in RBMs, so hopefully others will For instance, my jupyter notebook: demo/demo_stacked_auto_encoder.ipynb demonstrates the reconstruction errors of DBM which is a Stacked Auto-Encoder. What are Restricted Boltzmann Machines (RBM)?
