What is stacked RNN?
Stacking RNNs simply means feeding the output of one RNN layer to another RNN layer. The RNN layers can output sequences (that is, output at each time step) and these can be fed, like any input sequence, into the subsequent RNN layer.
Why LSTM is better than RNN?
LSTM networks combat the RNN's vanishing gradients or long-term dependence issue. Gradient vanishing refers to the loss of information in a neural network as connections recur over a longer period. In simple words, LSTM tackles gradient vanishing by ignoring useless data/information in the network.
What is hidden size in RNN Pytorch?
hidden_size – The number of features in the hidden state h. num_layers – Number of recurrent layers. E.g., setting num_layers=2 would mean stacking two RNNs together to form a stacked RNN , with the second RNN taking in outputs of the first RNN and computing the final results. Default: 1.
