Deep Learning - Crash Course 2023 - ReLU, SoftMax, and Cross Entropy

The video tutorial covers various activation functions used in deep learning, including sigmoid, tanh, ReLU, and softmax. It explains how these functions work, their mathematical representations, and their applications in binary and multiclass classification problems. The tutorial also discusses the use of cross entropy loss for evaluating classification models, emphasizing its effectiveness in handling probability-based outputs.

How does the softmax function provide a probability distribution for multiclass classification problems?

What is cross-entropy loss and why is it used in classification problems?

Discuss the relationship between predicted probabilities and actual outcomes in the context of cross-entropy loss.
