Frequently Asked Questions about Lightgbm
What is Lightgbm?
LightGBM (Light Gradient Boosting Machine) is a fast, distributed, high-performance gradient boosting framework based on decision tree algorithms, used for ranking, classification, and many other machine learning tasks.
What are the primary use cases for Lightgbm?
Binary and multiclass classification. Regression problems. Ranking tasks (learning-to-rank). Feature selection and importance analysis. Integration in ML pipelines for large-scale structured data
What are the strengths of Lightgbm?
High-speed training and low memory usage. Excellent predictive accuracy. Handles large datasets efficiently. Supports parallel, GPU, and distributed learning. Works well with sparse data and categorical variables
What are the limitations of Lightgbm?
Leaf-wise tree growth can overfit on small datasets. Less interpretable than simple decision trees. Parameter tuning is essential for optimal performance. Not ideal for extremely small datasets. Python API is feature-rich but some advanced options are less documented
