Frequently Asked Questions
What is the typical inference latency of a compiled XGBoost model?↓
Compiled C++ XGBoost model artifacts score tabular payloads in sub-5ms, outperforming deep neural networks by 10x on CPU hardware.
How does XGBoost handle missing tabular data values?↓
XGBoost automatically learns default branch directions for missing feature values during tree node splitting.
Can XGBoost models run on GPU infrastructure?↓
Yes. Setting the tree_method parameter to hist with device='cuda' accelerates both model training and batch scoring by up to 20x.
Who owns the trained XGBoost model artifacts and feature pipelines?↓
Your organization holds 100% legal ownership of all model weights, feature transformers, and scoring API code.
