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.

Introducing FLAML

FLAML (Fast and Lightweight AutoML) is a Python library developed by Microsoft Research [1]. It is designed to produce high-quality ML models with low computational cost automatically. The primary aim of FLAML is to minimize the resources required to tune hyperparameters and identify optimal ML models, making AutoML more accessible and cost-effective, particularly for users with budget constraints.

FLAML offers several key features that set it apart. One of these is its efficiency. It provides a fast and lightweight solution for ML tasks, minimizing the time and computational resources needed. It achieves this without compromising the quality of the models it produces. FLAML also emphasizes its versatility across various ML algorithms and various application domains.

The core of FLAML’s efficiency lies in its novel, cost-effective search algorithms. These algorithms intelligently explore the hyperparameter space, initially focusing on “cheap”...
