2a: Probability, Generalization and Over�tting Week 2: Overview In this module, we will brie�y review certain topics from probability which are essential for deep learning, and we will introduce the issue of generalization and over�tting in supervised learning. We will then discuss cross entropy and softmax, which are used for classi�cation tasks as alternatives to […]
