Consider functionally reusability and possibility of flexible design, you should use not FacadeEncoderDecoder but EncoderDecoderController as follows. 1601-1608). Omitting so-called peephole connection, it makes possible to combine the activations in LSTM gates into an affine transformation below. Furthermore, activation functions are as follows: and the acitivation of memory cell and hidden units are calculated as follows: LSTM-RTRBM model integrates the ability of LSTM in memorizing and retrieving useful history information, together with the advantage of RBM in high dimensional data modelling(Lyu, Q., Wu, Z., Zhu, J., & Meng, H. 2015, June). (2012, September). In the visible layer, this model has so-called local receptive fields by connecting each first hidden unit only to a subset of the visible units, corresponding to one of four square patches. Developed and maintained by the Python community, for the Python community. Ghifary, M., Kleijn, W. B., Zhang, M., Balduzzi, D., & Li, W. (2016, October).

As more usecases, RTRBM, RNN-RBM, and LSTM-RTRBM can learn dependency structures in temporal patterns such as music, natural sentences, and n-gram. Springer, Cham. 802-810). Then sampling of observed data points is is as following: While the hidden units are binary during inference and sampling, it is the mean-field value that is transmitted to its successors. The RTRBM can be understood as a sequence of conditional RBMs whose parameters are the output of a deterministic RNN, with the constraint that the hidden units must describe the conditional distributions. If you want to tie the weights, set the tied_graph as follows. In International Symposium on Neural Networks (pp. The learning equations of RBM are introduced by performing control so that those gradients can become zero. Instantiate objects and execute learning. weight_arr_list is the list of weights of each links in DBM.
