- A training set is a set of data used in various areas of information science to discover potentially predictive relationships. Training sets are used in artificial intelligence, machine learning, genetic programming, intelligent systems, and statistics. In all these fields, a training set has much the same role and is often used in conjunction with a test set.

- QUOTE: A learning set of [math]\displaystyle{ L }[/math] consists of data [math]\displaystyle{ {(y_n, \mathbf{x}_n), n = 1,…,N} }[/math] where the [math]\displaystyle{ y }[/math]’s are either class labels or a numerical response.

- QUOTE: Inductive learning is the explicit or implicit creation of general concept or class descriptions from examples. Many induction problems can be described as follows. A training set of preclassified examples is given, where each example (also called observation or case) is described by a vector of features or attribute values, and the goal is to form a description that can be used to classify previously unseen examples with high accuracy.
