Theme A4

In machine learning, features are the pieces of information that help a computer make decisions.

You can think of them as the clues the computer looks at when trying to learn something.

For example, if you want a computer to predict the price of a house, the features might include

  • the house’s size
  • number of bedrooms
  • location
  • age

Feature selection is the process of choosing which of these clues are the most useful.

Not all features help the computer learn — some may be irrelevant or even confusing.

By selecting only the best features, we make the model faster, simpler, and often more accurate.
