The Machine Learning “Advent Calendar” Day 14: Softmax Regression in Excel
Softmax Regression is simply Logistic Regression extended to multiple classes.
By computing one linear score per class and normalizing them with Softmax, we obtain multiclass probabilities without changing the core logic.
The loss, the gradients, and the optimization remain the same.
