LSTM unit: cell state dimension When we fit an LSTM model, each LSTM has a cell state which contains the information we want. I am wondering what's the dimension in the cell state (i.e. cell state itself should be a vector, then how large is the vector?)?


(from http://colah.github.io/posts/2015-08-Understanding-LSTMs/ )

i.e. In the above architecture, how do we determine the dimension of the matrix Wc?

If I am using Keras package, how do I find the Cell state dimensions of each LSTM unit? Is it something that one can adjust? 

Thank you!
In Keras, the first argument in LSTM gives the dimensionality of the cell state.
