How it works
A discrete feature is a type of categorical variable that has a limited, countable set of possible values. Examples include 'color' (red, green, blue) or 'day of the week' (Monday, Tuesday, etc.). These features are often represented numerically using techniques like one-hot encoding or embedding layers.
