[R] multilabel classification XGBoost and hyperparameter tuning

[Agnes g2g]

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?

Bye,
Agnes

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. Have you looked here:  https://cran.r-project.org/web/views/Cluster.html
or here: https://cran.r-project.org/web/views/MachineLearning.html

Cran's "task views" are a useful resource for such "does R have...?" questions.

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!

Bye,
Agnes
