Book Description

Deep learning enables efficient and accurate learning from a massive amount of data. This book will help you overcome a number of challenges using various deep learning algorithms and architectures with R programming.

This book starts with a brief overview of machine learning and deep learning and how to build your first neural network. You'll understand the architecture of various deep learning algorithms and their applicable fields, learn how to build deep learning models, optimize hyperparameters, and evaluate model performance. Various deep learning applications in image processing, natural language processing (NLP), recommendation systems, and predictive analytics will also be covered. Later chapters will show you how to tackle recognition problems such as image recognition and signal detection, programmatically summarize documents, conduct topic modeling, and forecast stock market prices. Toward the end of the book, you will learn the common applications of GANs and how to build a face generation model using them. Finally, you'll get to grips with using reinforcement learning and deep reinforcement learning to solve various real-world problems.

By the end of this deep learning book, you will be able to build and deploy your own deep learning applications using appropriate frameworks and algorithms.

What you will learn

• Design a feedforward neural network to see how the activation function computes an output
• Create an image recognition model using convolutional neural networks (CNNs)
• Prepare data, decide hidden layers and neurons and train your model with the backpropagation algorithm
• Apply text cleaning techniques to remove uninformative text using NLP
• Build, train, and evaluate a GAN model for face generation
• Understand the concept and implementation of reinforcement learning in R
