Neural Network Projects with Python

Overview of this book

Neural networks are at the core of recent AI advances, providing some of the best resolutions to many real-world problems, including image recognition, medical diagnosis, text analysis, and more. This book goes through some basic neural network and deep learning concepts, as well as some popular libraries in Python for implementing them. It contains practical demonstrations of neural networks in domains such as fare prediction, image classification, sentiment analysis, and more. In each case, the book provides a problem statement, the specific neural network architecture required to tackle that problem, the reasoning behind the algorithm used, and the associated Python code to implement the solution from scratch. In the process, you will gain hands-on experience with using popular Python libraries such as Keras to build and train your own neural networks from scratch. By the end of this book, you will have mastered the different neural network architectures and created cutting-edge AI projects in Python that will immediately strengthen your machine learning portfolio.

Requirements of face recognition systems

At this point, you should be fairly familiar with using neural networks for image recognition tasks. In Chapter 4, Cats Versus Dogs – Image Classification Using CNNs, we built a CNN for classifying images of cats versus dogs. Can the same techniques be used in facial recognition? Sadly, CNNs fall short for this task. To understand why, we need to look at the requirements of facial recognition systems.

Speed

The first requirement of a facial recognition system is that they need to be fast. If we look at the onboarding process of the facial recognition systems in our smartphones, we usually need to use the front-facing camera in the phone to scan our face at various angles for...
