In humans this is the process of taking short term memory and converting it to long term memory involves a process called consolidation where the structure of the physical brain changes, I guess this would be tantamount to a reweighting of the neural net. It's generally not a one shot thing, especially as the concepts get more complex and have more parts to learn.

One of the things humans do is forget a lot of unimportant crap so we're not constantly rewriting our brains. Of course there is a the issue of how do we make sure we're training our AI how to learn multiplication and not feeding it a diet of junk food information/fake news too.
