Sequences of Data

The core reason that recurrent neural networks are exciting is that they allow us to operate over sequences of vectors: sequences in the input, the output, or in some cases, both!

Most RNN's expect to see a sequence of data in a fixed batch size, much like we've seen images processed in fixed batch sizes. The batches of data affect how the hidden state of an RNN train, so next you'll learn more about batching data.
