Web9 de jun. de 2024 · Models are trained using the OOF training sets and evaluated with the validation sets, resulting in k model accuracy measurements. Instead of determining the best model and throwing away the rest, AutoGluon bags all models and obtains OOF predictions from each model on the partition it did not see during training. Web10 de jan. de 2024 · To avoid overfitting, cross-validation is usually used to predict the OOF (out-of-fold) part of the training set. There are two different variants available in this package but I’m going to describe ‘Variant A’ in this paragraph. To get the final predictions in this variant, we take the mean or mode of all of our predictions.

WebThese OOF predictions are used as features to train a stacking model, which simultaneously learns weights for each base model. These weights are used to combine the OOF predictions to form the final prediction. The validation datasets for each fold are used for hyperparameter tuning of all base models and the stacking model.
