Overview of this book

Machine Learning with LightGBM and Python is a comprehensive guide to learning the basics of machine learning and progressing to building scalable machine learning systems that are ready for release. This book will get you acquainted with the high-performance gradient-boosting LightGBM framework and show you how it can be used to solve various machine-learning problems to produce highly accurate, robust, and predictive solutions. Starting with simple machine learning models in scikit-learn, you’ll explore the intricacies of gradient boosting machines and LightGBM. You’ll be guided through various case studies to better understand the data science processes and learn how to practically apply your skills to real-world problems. As you progress, you’ll elevate your software engineering skills by learning how to build and integrate scalable machine-learning pipelines to process data, train models, and deploy them to serve secure APIs using Python tools such as FastAPI. By the end of this book, you’ll be well equipped to use various -of-the-art tools that will help you build production-ready systems, including FLAML for AutoML, PostgresML for operating ML pipelines using Postgres, high-performance distributed training and serving via Dask, and creating and running models in the Cloud with AWS Sagemaker.

Summary

In conclusion, this chapter looked at the two most common methods of ensemble learning for decision trees: bagging and boosting. We looked at the Random Forests and ExtraTrees algorithms, which build decision tree ensembles using bagging.

This chapter also gave a detailed overview of boosting in decision trees by going through the GBDT algorithm step by step, illustrating how gradient boosting is applied. We covered practical examples of random forests, ExtraTrees, and GBDTs for scikit-learn.

Finally, we looked at how dropouts can be applied to GBDTs with the DART algorithm. We now thoroughly understand decision tree ensemble techniques and are ready to dive deep into LightGBM.

The next chapter introduces the LightGBM library in detail, both the theoretical advancements made by the library and the practical application thereof. We will also look at using LightGBM with Python to solve ML problems.
