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.

Machine Learning and Neural Networks 101

Artificial intelligence (AI) has captured much of our attention in recent years. From face recognition security systems in our smartphones to booking an Uber ride through Alexa, AI has become ubiquitous in our everyday lives. Still, we are constantly being reminded that the full potential of AI has not yet been realized, and that AI will become an even bigger transformative factor in our lives.

When we look at the horizon, we can see the relentless progression of AI with its promise to better our everyday lives. Powered by AI, self-driving cars are becoming less science fiction, and more of a reality. Self-driving cars aim to reduce traffic accidents by eliminating human error, ultimately improving our lives. Similarly, the usage of AI in healthcare promises to improve outcomes. Notably, the UK's National Health Service has announced an ambitious AI project to diagnose early-stage cancer, which can potentially save thousands of lives.

The transformative nature of AI has led experts to call it the fourth industrial revolution. AI is the catalyst that will shape modern industries, and having knowledge of AI is essential in this new world. By the end of this book, you will have a better understanding of the algorithms that power AI, and will have developed real-life projects using these cutting-edge algorithms.

In this chapter, we will cover the following topics:

  • A primer on machine learning and neural networks
  • Setting up your computer for machine learning
  • Executing your machine learning projects from start to finish using the machine learning workflow
  • Creating your own neural network from scratch in Python without using a machine learning library
  • Using pandas for data analysis in Python
  • Leveraging machine learning libraries such as Keras to build powerful neural networks
