Hi gessha hope your well!!
Nothing wrong will a little seff-plugging, I heard a quote once which went " Early to, Early to rise, its not much use if you donβt advertise"
I enjoyed reading your post and was intrigued that the subject uses the same principle as https://en.wikipedia.org/wiki/Johari_window. to help classify the types of unknown classes. Looking forward to your future posts which may contain a few easy code examples.
