Nettet27. jul. 2024 · Why Stacking? I used Linear regression first then tried adding L1 and L2 regularization into it. Then I did it by XGB and LightGBM which performed better than linear models in test data-set. NettetStacking (a.k.a Stack Generalization) is an ensemble technique that uses meta-learning for generating predictions. It can harness the capabilities of well-performing as well as weakly-performing models on a classification or regression task and make predictions with better performance than any other single model in the ensemble. celta jobs sydney https://gomeztaxservices.com

Here is the lin. regression code: The Bayes optimal classifier is a classification technique. It is an ensemble of all the hypotheses in the hypothesis space. On average, no other ensemble can outperform it. The naive Bayes optimal classifier is a version of this that assumes that the data is conditionally independent on the class and makes the computation more feasible.
