Add XGBoost and Naive Bayes to metalearner_algorithm options in Stacked Ensemble #8674
Comments
Erin LeDell commented: I removed “PSVM” from the title because we had to remove the algo from the list of metalearner options until a bug is fixed. [https://github.com//pull/4341|https://github.com//pull/4341|smart-link] |
Abhinav Sharma commented: Hi team, It seems that the {{naivebayes}} and {{xgboost}} meta-learners , the stacked ensemble does not accept the {{metalearner_params}} option at all with {{v3.30.0.4}} {quote}Moreover, for the stacked ensemble with {{xgboost}} meta-learner it is not even possible to inspect the metalearner via {{se_model_with_xgb_metalearner.metalearner()}} as it throws an error. UPDATE: Whoops, for the second part I realized it’s because I was inspecting the model on a windows machine. |
Abhinav Sharma commented: Would you prefer that I create a bug report for this? |
Erin LeDell commented: [~accountid:557058:d55d2d14-5709-435a-be18-0436a70f4414] Thanks for the report. If you can, a new/separate Jira with an example would be great! (Otherwise we can create one). |
Abhinav Sharma commented: @erin, I’ve created and explained the task over here [https://h2oai.atlassian.net/browse/PUBDEV-7907|https://h2oai.atlassian.net/browse/PUBDEV-7907|smart-link] P.S. Thanks for the great work on Stacked Ensembles and H2O, I’ve learnt a lot from your thesis and subsequent work! |

We should have all the available supervised algos as options for the metalearner algorithm. Currently its hardcoded to this list:
{quote}{{metalearner_algorithm = c("AUTO", "glm", "gbm", "drf", "deeplearning")}}{quote}
Should be:
{quote}{{metalearner_algorithm = c("AUTO", "glm", "gbm", "drf", "deeplearning", "xgboost", "naivebayes", "psvm",)}}{quote}
