UnverifiedEnd-to-end joint training can avoid the cumulative propagation of errors that occurs in modular cascaded architectures, which is the fundamental reason it performs better in complex environments.73% similarUnverifiedEnsemble Learning improves overall predictive performance by combining multiple base learners.73% similarUnverifiedPAC learning theory and VC dimension provide a theoretical framework for understanding generalization; higher model complexity yields better fitting on the training set but may reduce generalization ability, which is the bias-variance tradeoff.71% similarUnverifiedThe main schools of ensemble learning include Bagging (variance reduction), Boosting (bias reduction), and Stacking.71% similar
