Hidden state and cell state lstm
WebThe LSTM model also have hidden states that are updated between recurrent cells. In fact, the LSTM layer has two types of states: hidden state and cell states that are passed between the LSTM cells. However, only hidden states are passed to the next layer.

Fundamentally, LSTM consists of three type of gates, namely forget gate f ( t ), input gate i ( t ) and output gate o ( t ) which decides relevant and irrelevant information …
Web20 de jul. de 2016 · 2 Answers. Sorted by: 12. Normally, you would set the initial states to zero, but the network is going to learn to adapt to that initial state. The following article suggests learning the initial hidden states or using random noise. Basically, if your data includes many short sequences, then training the initial state can accelerate learning. Web12 de abr. de 2024 · GRU stands for gated recurrent unit, and it has a simpler structure than LSTM, with two gates (reset and update) that regulate the update of the hidden state.
