Weight Initialization: Tricks of the Trade

This lecture covers the importance of smart weight initialization in artificial neural networks to accelerate learning during gradient descent. It discusses the normalization of data, random initialization of weights, and the significance of the square root of N. The instructor explains how different patterns affect the activation of neurons and the distribution of activation in layer 1. The lecture also delves into the linear and nonlinear processing in the forward pass, emphasizing the exploitation of nonlinearities and the impact of weight initialization on the network's performance.
