Doodle classification visualization

Hello,

I've created simple visualization for doodle classification example. It shows every doodle with coresponding prediction from NN.

Sample screenshot:


white background = NN was correct
red background = guessed "cat"
green background = guessed "rainbow"
blue background = guessed "train"

In first table in console each row is number of mistakes for every pair label:classification.

Second table is raw list of wrong guesses in format: (index), doodle number, label, classification, guess "cat", guess "rainbow", guess "train".

In overall, looks like NN is pretty consistent with rainbow doodles, but not so much with cats and trains.
