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.

Introduction to Convolutional Neural Networks

In data science, a convolutional neural network (CNN) is specific kind of deep learning architecture that uses the convolution operation to extract relevant explanatory features for the input image. CNN layers are connected as a feed-forward neural network while using this convolution operation to mimic how the human brain functions while trying to recognize objects. Individual cortical neurons respond to stimuli in a restricted region of space known as the receptive field. In particular, biomedical imaging problems could be challenging sometimes, but in this chapter, we'll see how to use CNN in order to discover patterns in this image.

The following topics will be covered in this chapter:

  • The convolution operation
  • Motivation
  • Different layers of CNNs
  • CNN basic example: MNIST digit classification
