Ensemble machine learning combines the power of multiple machine learning approaches, working together to deliver models that are highly performant and highly accurate.
Inside Ensemble Methods for Machine Learning you will
Ensemble machine learning trains a diverse group of machine learning models to work together, aggregating their output to deliver richer results than a single model. Now in Ensemble Methods for Machine Learning you’ll discover core ensemble methods that have proven records in both data science competitions and real-world applications. Hands-on case studies show you how each algorithm works in production. By the time you're done, you'll know the benefits, limitations, and practical methods of applying ensemble machine learning to real-world data, and be ready to build more explainable ML systems.

About the Technology
Automatically compare, contrast, and blend the output from multiple models to squeeze the best results from your data. Ensemble machine learning applies a “wisdom of crowds” method that dodges the inaccuracies and limitations of a single model. By basing responses on multiple perspectives, this innovative approach can deliver robust predictions even without massive datasets.
About the Book
Ensemble Methods for Machine Learning teaches you practical techniques for applying multiple ML approaches simultaneously. Each chapter contains a unique case study that demonstrates a fully functional ensemble method, with examples including medical diagnosis, sentiment analysis, handwriting classification, and more. There’s no complex math or theory—you’ll learn in a visuals-first manner, with ample code for easy experimentation!

Engaging examples to explain the Why of ensemble learning. Code examples of ensemble machine learning along with graphical representation of evaluation metrics terminology and types for ensemble methods and how they work Ways to perform model aggregation It was fun to see how a randomforest works, something we use so often. Exhaustive coverage of both heterogeneous and parallel ensembles and ways of combining predictions The book also covers loss functions Real world examples and case studies I used to go though kaggle solutions which used ensemble models and wondered about the reasoning behind choosing specific ensemble models. This book can be helpful to follow through Covers ensemble to both classification and regression, also handling categorical features, explaining models
