Deep Learning for Beginners

By: Dr. Pablo Rivas

Overview of this book

With information on the web exponentially increasing, it has become more difficult than ever to navigate through everything to find reliable content that will help you get started with deep learning. This book is designed to help you if you're a beginner looking to work on deep learning and build deep learning models from scratch, and you already have the basic mathematical and programming knowledge required to get started. The book begins with a basic overview of machine learning, guiding you through setting up popular Python frameworks. You will also understand how to prepare data by cleaning and preprocessing it for deep learning, and gradually go on to explore neural networks. A dedicated section will give you insights into the working of neural networks by helping you get hands-on with training single and multiple layers of neurons. Later, you will cover popular neural network architectures such as CNNs, RNNs, AEs, VAEs, and GANs with the help of simple examples, and learn how to build models from scratch. At the end of each chapter, you will find a question and answer section to help you test what you've learned through the course of the book. By the end of this book, you'll be well-versed with deep learning concepts and have the knowledge you need to use specific algorithms with various tools for different tasks.

Real-valued data and univariate regression

Knowing how to deal with categorical data is very important when using classification models based on deep learning; however, knowing how to prepare data for regression is as important. Data that contains continuous-like real values, such as temperature, prices, weight, speed, and others, is suitable for regression; that is, if we have a dataset with columns of different types of values, and one of those is real-valued data, we could perform regression on that column. This implies that we could use all the rest of the dataset to predict the values on that column. This is known as univariate regression, or regression on one variable.

Most machine learning methodologies work better if the data for regression is normalized. By that, we mean that the data will have special statistical properties that will make calculations more stable. This is critical for many deep learning algorithms that suffer from vanishing or exploding gradients (Hanin, B....
