Researchers have developed a novel gradient boosting algorithm called parallel gradient boosting, designed to efficiently estimate conditional distributions. This method trains a single base model per iteration, regardless of the number of targets, leading to significant performance gains. The algorithm demonstrates convergence and, in the context of multiple quantile regression, achieves similar prediction quality to state-of-the-art libraries like XGBoost while being orders of magnitude faster. Empirical evaluations show its superiority over other estimators, particularly in high-dimensional scenarios with mixed or missing covariates. AI
