Table of Learner Capabilities and How to Try a Bunch of Learners Quickly

Gday,

I was wondering if there was a table somewhere listing all of the learners and perhaps columns for the different learner capabilities.

If nobody can suggest one then I will make one up as it seems like it would be useful.

Secondly, can anyone suggest the best way to try a bunch of learners with a single dataset and get the cross-validation accuracy for each? I want to try about 25 different learners on the data set and get accuracies, then change the preprocessing and get another set of accuracies etc.

Thanks!

    Hi,
    the simplest solution is the meta operator OperatorSelector. It selects one of its inner operators dependend on a parameter. This parameter might be iterated using the GridparameterOptimization. Then the index of the best Learner will be returned.

    Thanks so much for that! Sounds like what I was looking for.

    I will work out some way to get all of the results.

    There are so many different operators it takes a while to get around to them all.
