LSTM Long Term Dependencies Keras












0












$begingroup$


I am familiar with the LSTM unit (memory cell, forget gate, output gate etc) however I am struggling to see how this links to the LSTM implementation in Keras.



In Keras the input data structure for X is: (nb_samples, timesteps, input_dim).



Suppose that the shape of X is: (1000, timesteps = 10, 40).



1) Does this mean that the LSTM cells will only consider ‘batches’ of 10 previous time steps ?



2) Or is the output from LSTM cells passed between these sets of 10 timesteps I.e could you capture long term dependencies 50 timesteps out?
