Animated RNN, LSTM & GRU

Recurrent neural networks are a class of artificial neural networks which are often used with sequential data. The 3 most common types of recurrent neural networks are vanilla recurrent neural network (RNN), long short-term memory (LSTM) and gated recurrent units (GRU).

Here are the 3 GIFs (RNN, LSTM and GRU respectively) to help us understand what’s happening in each neural network. Note that they do not necessarily reflect the sequence of vectorised computations.
