feature
An input variable to a machine learning model.
Plain English Explanation
An input variable to a machine learning model. An example consists of one or more features. For instance, suppose you are training a model to determine the influence of weather conditions on student test scores. The following table shows three examples, each of which contains three features and one label:
Pressure | Test score | 998 | 92 | 1020 | 84 | 1012 | 87 | Contrast with label. See Supervised Learning in the Introduction to Machine Learning course for more information.
How is it used?
Practitioners refer to feature when building, training, or evaluating machine learning systems. It appears in research papers, product documentation, and technical discussions about AI capabilities and limitations.
