Deep Learning By Example

Overview of this book

Deep learning is a popular subset of machine learning, and it allows you to build complex models that are faster and give more accurate predictions. This book is your companion to take your first steps into the world of deep learning, with hands-on examples to boost your understanding of the topic. This book starts with a quick overview of the essential concepts of data science and machine learning which are required to get started with deep learning. It introduces you to Tensorflow, the most widely used machine learning library for training deep learning models. You will then work on your first deep learning problem by training a deep feed-forward neural network for digit classification, and move on to tackle other real-world problems in computer vision, language processing, sentiment analysis, and more. Advanced deep learning models such as generative adversarial networks and their applications are also covered in this book. By the end of this book, you will have a solid understanding of all the essential concepts in deep learning. With the help of the examples and code provided in this book, you will be equipped to train your own deep learning models with more confidence.

The TensorFlow environment

TensorFlow is another deep learning framework from Google and, as the name TensorFlow implies, it's derived from the operations which neural networks perform on multidimensional data arrays or tensors! It's literally a flow of tensors.

But first off, why are we going to use a deep learning framework in this book?

  • It scales machine learning code: Most of the research into deep learning and machine learning can be applied/attributed because of these deep learning frameworks. They have allowed data scientists to iterate extremely quickly and have made deep learning and other ML algorithms much more accessible to practitioners. Big companies such as Google, Facebook, and so on are using such deep learning frameworks to scale to billions of users.
  • It computes gradients: Deep learning frameworks can also compute gradients automatically. If you go...
