Introducing sequential data

Let’s begin our discussion of RNNs by looking at the nature of sequential data, which is more commonly known as sequence data or sequences. We will look at the unique properties of sequences that make them different from other kinds of data. We will then see how to represent sequential data and explore the various categories of models for sequential data, which are based on the input and output of a model. This will help us to explore the relationship between RNNs and sequences in this chapter.

Modeling sequential data – order matters

What makes sequences unique, compared to other types of data, is that elements in a sequence appear in a certain order and are not independent of each other. Typical machine learning algorithms for supervised learning assume that the input is independent and identically distributed (IID) data, which means that the training examples are mutually independent and have the same underlying distribution.
