Exploring LightGBM: Leaf-Wise Growth with GBDT and GOSS
LightGBM is a highly efficient gradient boosting framework. It has gained traction for its speed and performance, particularly with large and complex datasets. Developed by Microsoft, this powerful algorithm is known for its unique ability to handle large volumes of data with significant ease compared to traditional methods.
In this post, we will experiment with LightGBM framework on the Ames Housing dataset. In particular, we will shed some light on its versatile boosting strategies—Gradient Boosting Decision Tree (GBDT) and Gradient-based One-Side Sampling (GOSS). These strategies offer distinct advantages. Through this post, we will compare their performance and characteristics.
We begin by setting up LightGBM and proceed to examine its application in both theoretical and practical contexts.
Let’s get started.
