I would like to have an opinion on a recurrent issue i encounter with machine learning.
Regularly when i call the source code it fails with the following message:
"
Error in summary.connexion(connexion) : incorrect connexion :
"
I would like to have an opinion on a recurrent issue i encounter with machine learning.
3 questions please:
- what is the best library to run ensemble model?
- what is the difference between an ensemble model based on workflow_set(preproc, models, cross = TRUE)
and
Ensemble_stacks -> blend_predictions() -> fit_members() approach.? - when i call an ensemble model do i have do run parallel computing? I ask so because it seems that when
I run a doparallel library once i receive error message after like (! tune detected a parallel backend registered with foreach but no
backend registered with future. i Support for parallel processing with foreach was soft-deprecated in
tune 1.2.1. i See ?parallelism (?tune::parallelism()) to learn more. )
Thank you,
