概要	Ensemble Gaussian Process trains multiple independent GP experts on data subsets or overlapping regions, then combines their posterior predictions — means and variances — into a single probabilistic forecast. This approach retains the calibrated uncertainty estimates of standard GPs while overcoming their O(n³) cubic cost bottleneck, making probabilistic regression practical on datasets with thousands to millions of observations.	A voting ensemble trains several diverse classifiers independently and combines their predictions by a vote: hard voting picks the class chosen by the most models, while soft voting averages their class-probability estimates, optionally with per-model weights. The combination usually outperforms any individual member, and requires no additional training after the base models are fitted.
