PyTorch 코드는 이곳을 Sep 27, 2017 · In the second step, whether we get a deterministic output, or sample a stochastic one depends on autoencoder-decoder net design. In Chung’s paper, he used an Univariate Gaussian Model autoencoder-decoder, which is irrelevant to the variational design. 2. Training phase. During training we have only sequential data at hand. Sep 07, 2017 · The recurrent model we have used is a one layer sequential model. We used 6 LSTM nodes in the layer to which we gave input of shape (1,1), which is one input given to the network with one value. Summary of LSTM Model PyTorch is better for rapid prototyping in research, for hobbyists and for small scale projects. TensorFlow is better for large-scale deployments, especially when cross-platform and embedded deployment is a consideration.
