Monitor hyperparameter tuning progress, abort and provide best values found so far
I used "Tuned Model Hyperparameters" and it's taking longer than I expected (hours), with no indication of remaining progress. I hesitate to stop it because I would like to have information about the best solution found so far. The log only shows when each training started and stopped, but doesn't show the parameters tested at each attempt and the results.
It would also be useful to have a graphical view of the progress: Plot with X = iteration, Y = Each of the possible metrics (AUC, F-Score,...). This graphical view should be available as parameter tuning progresses, to help decide if tuning should continue or not (if the metrics stay flat for several iterations, it's not worth continuing).
In any case, if tuning is aborted, we should have access to the best solution found.
