Technical Definition
A single instance of data, consisting of features and possibly a label.
How it works
An example is the basic unit of data used in machine learning, representing one row of information. In supervised learning, an example can be labeled (including features and the correct output) for training, or unlabeled (only features) for making predictions during inference.
