Logistic Regression Cost Function Explained | Cross Entropy Loss Intuition & Math

In this video, we explain the Logistic Regression Cost Function in detail. You will learn what Cross Entropy Loss (Log Loss) is, why we use it instead of squared error, and how it helps us optimize logistic regression models using gradient descent.
