What is the difference between a feature and a label?

Question

I want to know the difference between a feature and a label with respect to machine learning. Can someone please explain this?

Answer 1

Label: Labels are referred to as the final output. The output classes can also be considered as labels. When data scientists speak of labeled data what they mean is a group of samples which have been tagged to one or more labels.

Feature: Features are defined as individual independent variables that act as input. Prediction models use features to make predictions. Moreover, you can also obtain new features from old features using a feature engineering method.

Example-

Suppose you want to categorize your friends by their weight and height into different groups like obese, fit, underweight. Here, the inputs are weight and height which acts as a feature and the group names(fit, obese, underweight) which are the final outcome is the label.

Hope this answer helps.
