Suggestion for ID suggestion improvement

[sebffischer]

I think a relatively common user error (at least for not so experienced users) is that they forget the prefixes when setting graph parameters: (e.g. nrounds instead of classif.xgboost.nrounds below.

The problem is that our "Did you mean" does not find the correct suggestions. I think this might be a common enough error to address this, e.g. by matching grepl("<user-param>$", param_set$ids).

library(mlr3verse)
#> Loading required package: mlr3
graph = po("pca") %>>%
  lrn("classif.xgboost")

graph$param_set$set_values(
  nrounds = 10
)
#> Error in self$assert(xs, sanitize = TRUE): Assertion on 'xs' failed: Parameter 'nrounds' not available. Did you mean 'pca.center' / 'pca.scale.' / 'pca.rank.'?.
