LightGBM

LightGBM is a gradient boosting framework that uses tree-based learning algorithms, designed for efficiency and speed with large datasets. It employs techniques like Gradient-based One-Side Sampling (GOSS) and Exclusive Feature Bundling (EFB) to handle high-dimensional data while reducing memory usage and training time. It is widely used for tasks like classification, regression, and ranking in machine learning.

Also known as: Light GBM, LGBM, Microsoft LightGBM, Light Gradient Boosting Machine, LightGBM Framework

Why learn LightGBM?

Developers should learn LightGBM when working on machine learning projects that involve large datasets or require fast training times, such as in competitions (e.g., Kaggle), real-time applications, or big data analytics. It is particularly useful for handling categorical features efficiently and outperforms many other gradient boosting implementations in terms of speed and accuracy, making it ideal for production environments where performance is critical.
