Overview

Despite its name, Logistic Regression is used for classification, not regression. It predicts the probability that an instance belongs to a particular category (e.g., Yes/No, Spam/Not Spam).

How it Works

It uses the Logistic Function (Sigmoid Function) to map any real-valued number into a value between 0 and 1, representing a probability.

Use Cases

  • Predicting whether a customer will churn.
  • Determining if a credit card transaction is fraudulent.
  • Medical diagnosis (e.g., presence or absence of a disease).
