About this course

This course presents an image classification example from a specific industry, and explains in detail how Deep Neural Networks actually do their work, in order produce meaningful results for use in machine learning models. Start off by watching a movie covering the standard workings of Artificial Neural Networks. In the following lesson, explore the ANN process further via an image recognition example and matching game. This lesson explores how key functions use actual data to drive computations, and proceed through a neural network in a full forward then backward pass. Every step is explained along the way.
