human mind

Usually when trying to learn something new I need to repeat the information multiple times for it to stick in my memory. It doesn't matter how important or interesting that knowledge might be. It requires a lot of work.

Then there are times when I just hear or see something just once, briefly. And then I can't get it out of my head even if I wanted to.

It would be nice to consciously be able to do that: learn things instantly without all the repetition, pondering and hard work. Having such a memory would be fantastic.

In machine learning one of the hottest topics recent has been deep learning. While the computer learns in this method with multiple levels of neural networks it's quite far from how we as humans learn.

There are different levels in our learning as well. Sometimes we just pick up random trivia or light topics. Other times we might need to study a bit more when we encounter a problem we can't yet solve with our current knowledge.  Or we want to do something new and need to start from the basics.
