What are sequence prediction problems?
Sequence prediction is a problem that involves using historical sequence information to predict the next value or values in the sequence. The sequence may be symbols like letters in a sentence or real values like those in a time series of prices.
What does each number in a sequence call?
Each number in a sequence is called a term . Each term in a sequence has a position (first, second, third and so on). For example, consider the sequence {5,15,25,35,…} In the sequence, each number is called a term.
When do we need to use sequence prediction?
In this, Tavish introduced us to an entirely new class of problems called Sequence Modelling, along with some very good examples of their use cases and applications. Sequence prediction is required whenever we can predict that a particular event is likely to be followed by another event and we need to predict that.
How are sequence predictions generated in machine learning?
Predictions at multiple future time steps are framed as output features to the model. This is the classical fixed-window approach of making multi-step predictions used by multilayer Perceptrons and other machine learning algorithms. Instead, the sequence predictions should be generated one time step at a time.

How is the cardinality of a sequence prediction model defined?
The model does take two values as input and predicts two values, but there is only a single sequence time step expressed for the input and predicted as output. The cardinality of the sequence prediction models defined above refers to time steps, not features (e.g. univariate or multivariate sequences).
