rename feature specification

this is a bit of a nitpick:

I suggest moving the "dependent feature" selection and "prediction type" out of (and perhaps above) the line "Feature Specification", or to rename "feature specification" to just "specification" or "task specification". It sounds weird to me to refer to the labelled data as a feature, since "features" typically refers to the independent variables, i.e. predictors, in supervised learning, not to the outcome/label/target.
