comment Why doesn't my expression evaluate at the subkernel?
Somebody more knowledgeable than me will probably have a better answer, but it looks as though the parameter testing for f2 needs to call fQ, and that function definition isn't automatically distributed to the other kernels.

comment ListPlot3D with the color choosen from another list
@ybeltukov There is a documented option for vertex colours, but the output seems to be a partially shaded surface and doesn't have anything you might refer to as a point, so I wonder what the questioner is really seeking here.

comment How to combine multiple rules?
Are you just seeking to apply a function to specific set of arguments as you would using the Map[] function ? Or is your goal something different ? Perhaps some input and output examples might make this more evident.

comment When using Classify[] on images, is preprocessing necessary?
As @DavidG.Stork points out, the ultimate answer to this is ... it depends. Generally having input which is uniform in features other than those specifically required for discrimination, such as image size, number of channels etc, will be beneficially for the learning algorithm. More detail of your specific application and data might produce more appropriate responses.

@Philipp Don't they say they thresholded it and then binarised it ?

comment How to train a convolutional neural net on images?
At this point in time Mathematica is not the most friendly platform for machine learning development. This is because, as you point out, most of its functionality is obscured.From the documentation, it isn't even easy to tell if the implementation supports sparse layer connectivity, or how you might specify that if it did, which you would need for your convolution neural network. Unless someone has done a fair amount of spelunking, a "hello world" example of the type you ask for might be a tall order.
