Further, the neurons in one layer do not connect to all the neurons in the next layer but only to a small region of it. Input with spatial structure, like images, cannot be modeled easily with the standard Vanilla LSTM. The 1D block is composed by a configurable number of filters, where the filter has a set size; a convolution operation is performed between the vector and the filter, producing as output a new vector with as many channels as the number of filters. If your 1d data vector is too large, just try subsampling, instead of a convolutional architecture. See Migration guide for more details. We now define and motivate the structure of the proposed model that we call the VAE-LSTM model.
