I would be happy with replacing this line here https://github.com/ja-thomas/autoxgboost/blob/b64048e603751bcba9b6e212c775baff8ababccb/R/autoxgboost.R#L171 with `crossval(lrn, task.train, measure)$aggr`. And yes, I would ignore `task.test` data here completely (on which the early-stopping is based). But...
Do we have an API for this now? If not, you could request this in the main issue tracker. However, you could use `getOMLRun(x, only.xml=TRUE)` from https://github.com/openml/openml-r/pull/347 this should be...
The API is not working, see https://github.com/openml/OpenML/issues/411#issuecomment-313318472 . Will have a look when this is fixed.
I started to work on this here https://github.com/openml/openml-r/pull/378
Done in https://github.com/openml/openml-r/pull/378, we now have the `listOMLSetup` function where you can provide a vector of setup.ids (e.g. from the `listOMLRunEvaluations`) and get their hyperparameter settings of each setup.
it's supported by the REST API but not 100% documented in https://www.openml.org/api_docs/#!/setup/get_setup_id
Nope, you can also ask for all parameter configurations of a specific flow. This is only one request and it already gives you more than one run (but a maximum...
Although, I see that we havn't solved this perfectly in mlr, this is the current status: 1) A flow is determined by its external.version (which is a crc32 hash generated...
