Welcome to the course Create Custom Layers in Keras! In this 1-hour long project-based course, you will learn how to create a custom layer in Keras and create a model using the custom layer. We will create a simplified version of a Parametric ReLU layer and use it in a neural network model. Then we will use the neural network to solve a multi-class classification problem. We will also compare our activation layer with the more commonly used ReLU activation layer.
