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 summary, this chapter discussed AutoML systems and their uses. Typical approaches to automating feature engineering, model selection, and tuning were discussed. We also mentioned the risks and caveats associated with using these systems.

The chapter also introduced FLAML, a library for AutoML that provides tools for automating the model selection and tuning process. We also presented CFO and BlendSearch, two efficient hyperparameter optimization algorithms provided by FLAML.

The practicalities of applying FLAML were shown in the form of a case study. In addition to FLAML, we showcased an open source tool called Featuretools, which provides functionality to automate feature engineering. We showed how to develop optimized models in fixed-time budgets using FLAML. Finally, we provided examples of using FLAML’s zero-shot AutoML functionality, which analyzes datasets against configurations for known problems to determine suitable hyperparameters, eliminating the...
