Overview of this book

Machine learning is transforming the way we understand and interact with the world around us. This book is the perfect guide for you to put your knowledge and skills into practice and use the Python ecosystem to cover key domains in machine learning. This second edition covers a range of libraries from the Python ecosystem, including TensorFlow and Keras, to help you implement real-world machine learning projects. The book begins by giving you an overview of machine learning with Python. With the help of complex datasets and optimized techniques, you’ll go on to understand how to apply advanced concepts and popular machine learning algorithms to real-world projects. Next, you’ll cover projects from domains such as predictive analytics to analyze the stock market and recommendation systems for GitHub repositories. In addition to this, you’ll also work on projects from the NLP domain to create a custom news feed using frameworks such as scikit-learn, TensorFlow, and Keras. Following this, you’ll learn how to build an advanced chatbot, and scale things up using PySpark. In the concluding chapters, you can look forward to exciting insights into deep learning and you'll even create an application using computer vision and neural networks. By the end of this book, you’ll be able to analyze data seamlessly and make a powerful impact through your projects.

Creating a supervised training set with Pocket

Before we can create a model of our taste in news articles, we need training data. This training data will be fed into our model in order to teach it to discriminate between the articles we'd be interested in and those we would not. To build this corpus, we will need to annotate a large number of articles to correspond to these interests. We'll label each article either y or n, indicating whether it is the type of article we would want to have sent to us in our daily digest or not.

To simplify this process, we'll use the Pocket app. Pocket is an application that allows you to save stories to read later. You simply install the browser extension, and then click on the Pocket icon in your browser's toolbar when you wish to save a story. The article is saved to your personal repository.
