LSTM ( 3, 3 ) # Input dim is 3, output dim is 3 inputs = # make a sequence of length 5 # initialize the hidden state. Part-of-speech tags, and a myriad of other things. We can use the hidden state to predict words in a language model, There is a corresponding hidden state \(h_t\), which in principleĬan contain information from arbitrary points earlier in the sequence. In the case of an LSTM, for each element in the sequence, So that information can propagate along as the network passes over the For example, its output could be used as part of the next input, Another example is the conditionalĪ recurrent neural network is a network that maintains some kind of The classical example of a sequence model is the Hidden Markov Models where there is some sort of dependence through time between your Sequence models are central to NLP: they are There is no state maintained by the network at all. Sequence Models and Long Short-Term Memory Networks ¶Īt this point, we have seen various feed-forward networks.
