Ensemble Learning
A core paradigm in machine learning that combines the predictions of multiple weak learners or diverse models to produce outputs more robust than any single model. Representative algorithms include Bagging, Boosting, Random Forest, and XGBoost.
Core Facts
Deep Ensembles train multiple independent networks and aggregate their predictive distributions, achieving the best performance but at the highest computational cost
Gradient Boosting is a class of ensemble learning algorithms that iteratively trains weak learners (typically decision trees), with each new model focusing on correcting the residuals from the previous round.

分位数回归、集成学习和贝叶斯方法三种不确定性估计路径各有取舍：分位数回归计算最省，集成学习实现简单但训练成本高，贝叶斯方法理论最优雅但收敛慢。
The biggest problem with a single decision tree is high variance and susceptibility to overfitting; ensemble learning compensates for this shortcoming through the trade-off of higher bias for lower variance.
The multi-dimensional cross-validation method employed by Dnipro is essentially a form of Ensemble Learning thinking.
