To do so I am taking Udacity’s online lesson on Intro to Deep Learning with PyTorch. RNN typically includes an input layer, a hidden layer, and an output layer, where the hidden state at a certain time t is determined by the input at the current time as well as by the hidden state. The hidden weight matrix is necessarily square - the number of hidden units remains the same, so there are the same number of inputs as there are outputs, so M must always equal K.
