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.

Linear models for regression

Linear regression models are the most basic type of regression models and are widely used in predictive data analysis. The overall idea of regression models is to examine two things:

  1. Does a set of explanatory features / input variables do a good job at predicting an output variable? Is the model using features that account for the variability in changes to the dependent variable (output variable)?
  2. Which features in particular are significant ones of the dependent variable? And in what way do they impact the dependent variable (indicated by the magnitude and sign of the parameters)? These regression parameters are used to explain the relationship between one output variable (dependent variable) and one or more input features (independent variables).

A regression equation will formulate the impact of the input variables (independent variables) on the...
