Re: [R] multilabel classification XGBoost and hyperparameter tuning
Hello Agnes, Yes, it is true, "xgboost" is not oriented for a "multi-label" classification. "xgboost" can handle "multi-class" but not "multi-label". Bue in "mlr", you can handle "multi-class" problems although not with "xgboost" a base learner algorithm. You can see here how you can handle that with "mlr": - https://mlr.mlr-org.com/articles/tutorial/multilabel.html Besides that, you can see if these other alternatives could work for your problem: - "utiml" was one of them but now it's not avaialble on CRAN ( https://github.com/rivolli/utiml). - And this other one "mldr" could help you out: https://cran.r-project.org/web/packages/mldr/vignettes/mldr.pdf. Thanks, Carlos.

Re: [R] multilabel classification XGBoost and hyperparameter tuning
Thank you for your reply. As far as I can see xgboost package does not provide multilabel classification. The mlr package uses a wrapper for xgboost, so I have used the package xgboost. But I still have the problem with the hyperparameter tuning. Did I understand you correctly? Do you have any other suggestion?

Re: [R] multilabel classification XGBoost and hyperparameter tuning
One other suggestion. Per the posting guide linked below, statistical issues such as your query on "hyperparameter tuning" are off topic on this list, as are questions about specific nonstandard packages. You might try posting on stats.stackexchange.com instead for help on such matters.

1. A web search on "xgboost R" brought up R package "xgboost" which you did not mention. Did you not first try a web search or did you find that it did not meet your needs? 2.

[R] multilabel classification XGBoost and hyperparameter tuning
Hi all, I want to do multilabel classification with XGBoost and tune hyperparameters. With the mlr package this does not seem possible, see https://stackoverflow.com/questions/67640953/feature-names-stored-in-object-and-newdata-are-different-using-mlr-package?noredirect=1#comment119651508_67640953 Any ideas how to solve this? What other packages support multilabel classification for XGBoost and has the possibility to tune hyperparameters? Thanks in advance!
