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.

Model building

We're finally ready to start building our CNN in Keras. In this section, we'll take two different approaches to model building. First, we'll start by building a relatively simple CNN consisting of a few layers. We'll take a look at the performance of the simple model, and discuss its pros and cons. Next, we'll use a model that was considered state-of-the art just a few years ago—the VGG16 model. We'll see how we can leverage on the pre-trained weights to adapt the VGG16 model for cats versus dogs image classification.

Building a simple CNN

In an earlier section, we showed how the fundamental building blocks of a CNN consist of a series of convolutional and pooling layers...
