Look at ClassifierMeasurements and see if it fits your needs.

comment Why is Random faster than RandomReal?
If the underlying generator can be accessed, I wonder if it could be used, instead? In other words, run the setup code, `` Random`InitializeGenerator``, and then run your code, followed by any teardown code. Just a thought; I'll try looking into it later.

comment Efficiently generating tuples with Outer
@march just note that Nothing only works in List and Association, so in a lot of cases where ##&[] is needed, Nothing won't work.

comment Efficiently generating tuples with Outer
@march ##&[] evaluates to Sequence[] which is broader in scope than Nothing. But, the biggest difference, AFAIK, is that they have different reactions to Hold. Sequence requires the SequenceHold attribute to hold it, Nothing is fine with HoldAll and its kin, e.g. If[a, first, Nothing] vs. If[a, first, Sequence[]]. Hence, the use of the function.

@Ziofil Nothing is a very new function. So, i'm not surprised you knew nothing about it.

comment ListPlot3D Link Tick Range to color gradient
It has to do with the custom color function and the potential for non-linearities in it, and a way to easily handle the ramifications is not known. So, we have to fudge things a bit. Give me a second to add to my answer.

That helps, at least enough that I can write up something coherent.

comment Classification problem using SVM methods
As to your previous question, we're using libsvm. As to the changing parameter, the default depends on the data set, itself. So, if the data set changes, it changes. I do not know how it is calculated, though.

comment ListPlot3D Link Tick Range to color gradient
I am not entirely sure what you are asking for, could you clarify it a bit? Also, there are several typos in your plotting code and I can only hazard a guess at what you intend. So, could you fix it and simplify it?

It seems setting "GammaScalingParameter", too, avoids the issue. I used 1/(340 Sqrt[2]) which is what ClassifierInformation[c, "Options"] told me.

Have you tried rescaling them, like multiply them by $10^4$?

comment Bar legend coloring doesn't correspond to array plot coloring in the expected way
@Edmund perspective and trade-offs based on who you satisfy. In other words, the usual stuff with complex systems. Evaluate won't protect it as they're inert, all the "magic" happens during the display phase; same with Graphics. So, Evaluate@legendfunction evaluates to legendfunction. It is curious that Pane does protect it, though.
