Python Machine Learning By Example - Third Edition

By: Yuxi (Hayden) Liu

Overview of this book

Python Machine Learning By Example, Third Edition serves as a comprehensive gateway into the world of machine learning (ML). With six new chapters, on topics including movie recommendation engine development with Naïve Bayes, recognizing faces with support vector machine, predicting stock prices with artificial neural networks, categorizing images of clothing with convolutional neural networks, predicting with sequences using recurring neural networks, and leveraging reinforcement learning for making decisions, the book has been considerably updated for the latest enterprise requirements. At the same time, this book provides actionable insights on the key fundamentals of ML with Python programming. Hayden applies his expertise to demonstrate implementations of algorithms in Python, both from scratch and with libraries. Each chapter walks through an industry-adopted application. With the help of realistic examples, you will gain an understanding of the mechanics of ML techniques in areas such as exploratory data analysis, feature engineering, classification, regression, clustering, and NLP. By the end of this ML Python book, you will have gained a broad picture of the ML ecosystem and will be well-versed in the best practices of applying ML techniques to solve problems.

How computers understand language – NLP

In Chapter 1Getting Started with Machine Learning and Python, I mentioned that machine learning-driven programs or computers are good at discovering event patterns by processing and working with data. When the data is well structured or well defined, such as in a Microsoft Excel spreadsheet table or a relational database table, it is intuitively obvious why machine learning is better at dealing with it than humans. Computers read such data the same way as humans, for example, revenue: 5,000,000 as the revenue being 5 million and age: 30 as the age being 30; then computers crunch assorted data and generate insights in a faster way than humans. However, when the data is unstructured, such as words with which humans communicate, news articles, or someone's speech in French, it seems that computers cannot understand words as well as humans do (yet).
