Deep Learning Fundamentals - Intro to Neural Networks - Weight Initialization explained | A way to reduce the vanishing gradient problem

Let's talk about how the weights in an artificial neural network are initialized, how this initialization affects the training process, and what YOU can do about it! To kick off our discussion on weight initialization, we're first going to discuss how these weights are initialized, and how these initialized values might negatively affect the training process. We'll see that these randomly initialized weights actually contribute to the vanishing and exploding gradient problem we covered in the last video. With this in mind, we'll then explore what we can do to influence how this initialization occurs. We'll see how Xavier initialization (also called Glorot initialization) can help combat this problem. Then, we'll see how we can specify how the weights for a given model are initialized in code using the kernel_initializer parameter for a given layer in Keras.
