What is softmax regularization and how does it work?

Softmax regularization is a technique used in machine learning to convert raw scores into probabilities. It helps in multi-class classification by ensuring that the output values sum to one, making them interpretable as probabilities.

Why is softmax regularization important in neural networks?

It's important because it allows the model to output a probability distribution over multiple classes, which is essential for tasks like classification. It helps in making decisions based on the likelihood of each class.

Can you give an example of how softmax is applied?

Sure! In a neural network for image classification, the final layer might use softmax to convert the logits (raw output scores) into probabilities for each class, like cat, dog, or bird.

Are there any alternatives to softmax regularization?

Yes, alternatives include sigmoid activation for binary classification and other techniques like the Gumbel-Softmax for differentiable sampling.
