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

This chapter presented two case studies on how to apply the data science process with LightGBM. The data science life cycle and the typical constituent steps were discussed in detail.

A case study involving wind turbine power generation was presented as an example of approaching a data problem while working through the life cycle. Feature engineering and how to handle outliers were discussed in detail. An example exploratory data analysis was performed with samples given for visualization. Model training and tuning were shown alongside a basic script for exporting and using the model as a program.

A second case study involving multi-class credit score classification was also presented. The data science process was again followed, with particular attention given to data cleaning and class imbalance problems in the dataset.

The next chapter discusses the AutoML framework FLAML and introduces the concept of machine learning pipelines.
