Book Description 

A surging interest in machine learning is due to the fact that it evolutionzies automation by learning patterns in data and using them to make predictions and decisions. Your ML journey starts with this book, as the second edition of the bestseller, Python Machine Learning By Example. 

Hayden's unique insights and expertise introduce you to important ML concepts and implementations of algorithms in Python both from scratch and with libraries. Each chapter of the book walks you through an industry adopted application. With the help of realistic examples, you will find it intriguing to acquire mechanics of ML techniques in areas such as exploratory data analysis, feature engineering, classification, regression, clustering, and NLP - they are no more obscure as you thought.

This critically extended and updated edition now includes implementation with trendy libraries including TensorFlow, gensim and Keras. The scikit-learn codes are also fully modernized. Even if you've read the last edition, you'll still be delighted to find plenty of new content, for example, neural network, dimensionality reduction, topic modeling, large-scale learning with Spark and word embedding. 

Toward the end, you will gather a broad picture of the ML ecosystem and best practices of applying ML techniques to meet new opportunities in today's world.
