Packt Publishing Limited (Verlag)
978-1-78961-285-1 (ISBN)
Combine popular machine learning techniques to create ensemble models using Python
Key Features
Implement ensemble models using algorithms such as random forests and AdaBoost
Apply boosting, bagging, and stacking ensemble methods to improve the prediction accuracy of your model
Explore real-world data sets and practical examples coded in scikit-learn and Keras
Book DescriptionEnsembling is a technique of combining two or more similar or dissimilar machine learning algorithms to create a model that delivers superior predictive power. This book will demonstrate how you can use a variety of weak algorithms to make a strong predictive model.
With its hands-on approach, you'll not only get up to speed on the basic theory but also the application of various ensemble learning techniques. Using examples and real-world datasets, you'll be able to produce better machine learning models to solve supervised learning problems such as classification and regression. Furthermore, you'll go on to leverage ensemble learning techniques such as clustering to produce unsupervised machine learning models. As you progress, the chapters will cover different machine learning algorithms that are widely used in the practical world to make predictions and classifications. You'll even get to grips with the use of Python libraries such as scikit-learn and Keras for implementing different ensemble models.
By the end of this book, you will be well-versed in ensemble learning, and have the skills you need to understand which ensemble method is required for which problem, and successfully implement them in real-world scenarios.
