Hands-On Ensemble Learning with Python

By: George Kyriakides, Konstantinos G. Margaritis

Overview of this book

Ensembling 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 with the basic theory but also the application of different 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. In addition to this, 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.

Summary

In this chapter, we explored the possibility of detecting fraudulent transactions using various ensemble learning methods. While some performed better than others, due to the dataset's nature, it is difficult to produce good results without resampling the dataset in some way (either over-sampling or under-sampling).

We were able to show how to use each ensemble learning method and how to explore the possibility of fine-tuning its respective parameters in order to achieve better performance. In the next chapter, we will try to leverage ensemble learning techniques in order to predict Bitcoin prices.
