In this step-by-step tutorial, you'll build a neural network from scratch as an introduction to the world of artificial intelligence (AI) in Python. You'll learn how to train your neural network and make accurate predictions based on a given dataset.
Your First Neural Network We’ll be using Python and TensorFlow to create a CNN that takes a small image of a typed digit from 0 to 9 and outputs what digit it is. This is a great use case to start with and will give you a good foundation for understanding key principl...
