I like the integrated approach of your autoML package.
Can optimization be improved (lower error with less training budget) compared to random tuning and frace optimization by including mlr hyperopt / mlrMBO as an option?
In mlrhyperopt, there is access included to a couple of standard tuning ranges according to their user fed hyperparameter "database", for several standard models.

I have used mlrhyperopt from time to time and found the results I got from that hyperparameter tuning api quite useful.

Whilst having used mlrHyperOpt to generate most of the hyper parameter grids internally in the package, I do not use it for all models.

Bayesian optimisation can be included, I excluded it due to installation issues when testing the package, quite quick to implement again. At the moment Iterated f-racing is also included if random tuning does not suffice.
