Full Chapter Overview

Getting Started with Machine Learning and Python

What is ML? Why do we need it? You will explore typical ML tasks and essential techniques of working with data and models.

Building a Movie Recommendation Engine with Naive Bayes

You will learn the fundamental concepts of classification, and build a movie recommender using Naive Bayes. You will practice fine-tuning a model - an important skill for every ML practitioner.

Recognizing Faces with Support Vector Machine

Support vector machine searches for a decision boundary to separate data from different classes. You will implement the algorithm and apply it to face recognition.

Predicting Online Ad Click-Through with Tree-Based Algorithms

Tree-based models (decision trees, random forests, boosted trees) throughout the course of solving the ad click-through rate problem. Feature importance, and model ensemble will also be covered.

Predicting Online Ad Click-Through with Logistic Regression

Logistic regression is a very scalable classification model. You will use it on large datasets, learn about categorical encoding, regularization, online learning, and stochastic gradient descent.

Scaling Up Prediction to Terabyte Click Logs

Parallel computing tools Apache Hadoop and Spark - a more scalable solution to massive ad click prediction.

Predicting Stock Prices with Regression Algorithms

Several popular regression algorithms, including linear regression, regression tree, and support vector regression for you to tackle a billion (or trillion) dollar problem - stock price prediction.

Predicting Stock Prices with Artificial Neural Networks

Neural network models in depth. You will start by building the simplest neural network and go deeper by adding more layers, and implement it using TensorFlow to predict stock prices.

Mining the 20 Newsgroups Dataset with Text Analysis Techniques

You will gain hands-on experience in neural language processing through working with text data, and visualize text data using dimension reduction techniques.

Discovering Underlying Topics in the Newsgroups Dataset with Clustering and Topic Modeling

Using K-means algorithm, matrix factorization and latent Dirichlet allocation, you will be amused by how many interesting themes are mined from the 20 newsgroups dataset!

Machine Learning Best Practices

Get ready for real-world projects and follow 21 best practices throughout the entire machine learning workflow.

Categorizing Images of Clothing with Convolutional Neural Networks

Building blocks and architecture of CNNs, and their implementation in TensorFlow. You will categorize clothing images, and utilize data augmentation techniques to boost the CNN classifier.

Making Predictions with Sequences using Recurrent Neural Networks

Sequential learning, and how RNNs are well suited for it. You will solve two sequential learning problems: movie review sentiment analysis and text auto-generation.

Making Decisions in Complex Environments with Reinforcement Learning

Learning from experience, and interacting with the environment. You will explore various RL environments with dynamic programming algorithms, Monte Carlo learning, and Q-learning.

Endorsements from Guru

Python Machine Learning by Example, Third Edition is ideal for those who learn best by doing. I think for the ML beginner, this book may be a better starting point than one with much more about theory and less focus on the practical aspects of ML."
