1. Features

• Definition: Features are the input variables or attributes used by a machine learning model to make predictions.

• They represent the characteristics, properties, or measurable data points of the problem.

• Can be numeric, categorical, text, or image data depending on the task.

• Examples:

  • In predicting house prices → features include square footage, number of bedrooms, location.

  • In spam detection → features include email subject words, length of email, presence of attachments.

  • In image recognition → pixel values of the image act as features.

2. Labels

• Definition: Labels are the output variable or the target that the model is trained to predict.

• They represent the ground truth during training.

• The type of label depends on the task (numeric for regression, categorical for classification).

• Examples:

  • In house price prediction → the label is the actual price of the house.

  • In spam detection → the label is “spam” or “not spam.”

  • In digit recognition → the label is the number (0–9) shown in the image.

Summary

• Features = Inputs (X) → what we feed into the model.

• Labels = Outputs (Y) → what the model learns to predict.

👉 Think of it like this:
If you’re a teacher grading exams:

• Features = the answers students write.

• Label = the final grade you assign.
