comment Dataset: get number of levels and elements
One could probably get the number of elements similary, taking the Total instead of 1 + Max

@Mr.Wizard I see I had already posted an answer there that wasn't very much appreciated probably saying the same thing. Feel free to merge, but I wouldn't press for an accept, and I'll delete that one

@MichaelE2 I just intended to mean that that section was for those that would say too-long-didn't-read to a long post, and the second to those that would complain of a lazy incomplete question.

comment V10's Operator Forms - what are they good for?
The ~(#2 /@ #1 &)~ form is nicer than the //Max/@#& in that you keep the ability to continue with other infixes like ~Position~2 without having precedence problems. +1

comment Classify the classic tennis example
Overfitting so that the original points all match is something undesirable, but it depends on the method. It shouldn't happen with nearest neighbor (with a single neighbor)

Also, these machine learning functions seem to be very picky about receiveng the options/parameters as strings or as symbols. I most of mma, the string versions work even if the symbol exists, but not here. To make matters worse, ClassPriors is a symbol as an option and a string as a property (but not all properties are strings, such as Method). I'll probably report this since it is pointlessly annoying and inconsistent with other mma functions
