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.

Cats Versus Dogs - Image Classification Using CNNs

In this chapter, we will use convolutional neural networks (CNNs) to create a classifier that can predict whether a given image contains a cat or a dog.

This project marks the first in a series of projects where we will use neural networks for image recognition and computer vision problems. As we shall see, neural networks have proven to be an extremely effective tool for solving problems in computer vision.

In this chapter, we will cover the following topics:

  • Motivation for the problem that we're trying to tackle: image recognition
  • Neural networks and deep learning for computer vision
  • Understanding convolution and max pooling
  • Architecture of CNNs
  • Training CNNs in Keras
  • Using transfer learning to leverage on a state-of-the art neural network
  • Analysis of our results
