In this chapter, we covered a number of methods for analyzing text data. We started with techniques for extracting elements from text data, such as taking a sentence and breaking it into tokens and comparing term frequency, along with collecting topics and identifying the best summary sentence and extracting these from the text. Next, we used some embedding techniques to add additional details to our data, such as parts of speech and named entity recognition. Lastly, we used an RBM model to find latent features in the input data and stacked these RBM models to perform a classification task. In the next chapter, we will look at using deep learning for time series tasks, such as predicting stock prices, in particular.

Overview of this book
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.
