Okay, it is time to explain bear brain (It is an imagined brain because I don’t know how the real brain works. 
)
I won’t discuss visual recognition because it is way beyond my capability.
Here is an example.
If I ask which sun is hotter?
A human will need to see the emotions in lines and colors to answer.
It is not merely a classification problem.
It has a lot of things to do with experience and other sense.
Thus, I am only going to give a theoretical arrangement of memory in a hypothetical brain.
I know it smells fishy, but please bear with me.
