Multiple Boosting Calibration Trees (MBCT): Feature‑Aware Binning for Uncertainty Calibration
The paper introduces Multiple Boosting Calibration Trees, a feature‑aware binning ensemble that uses a new multi‑view calibration error metric and boosting to learn personalized, non‑monotonic calibrations for CTR prediction, achieving lower calibration error and higher click‑through rates and revenue than existing methods in both offline and online tests.
