Understanding Gradient Boosting

Gradient Boosting improves predictions by building multiple trees sequentially.

The process works as follows:

  1. Train the first tree.
  2. Measure prediction errors.
  3. Train a second tree to correct those errors.
  4. Continue building additional trees.
  5. Combine all predictions.

Each new tree focuses on mistakes made by previous trees.

As a result, the overall model becomes increasingly accurate.

XGBoost enhances this process through advanced optimization techniques that improve both speed and performance.
