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.

Feature engineering

Feature engineering is one of the key components that contribute to the model's performance. A simple model with the right features can perform better than a complicated one with poor features. You can think of the feature engineering process as the most important step in determining your predictive model's success or failure. Feature engineering will be much easier if you understand the data.

Feature engineering is used extensively by anyone who uses machine learning to solve only one question, which is: how do you get the most out of your data samples for predictive modeling? This is the problem that the process and practice of feature engineering solves, and the success of your data science skills starts by knowing how to represent your data well.

Predictive modeling is a formula or rule that transforms a list of features or input variables (x1...
