	Everyone is complaining about machine learning and AI in one way or another. So I decided to take a free course just to see what's going on. https://scuti.neocities.org/pages/ud120-online-course-review The course I took covers supervised machine learning, which would be used in a "music recommendation system". It doesn't cover unsupervised machine learning or generative AI. But I think it's a surprise how much of an impact middle school mathematics and a bit of Python can make. I also didn't expect linear regression to be considered a machine learning algorithm. Tell me if any of this is a surprise to you. post# 5150

Welcome to Blue Dwarf.

Today, a motivated individual can get the equivalent of a college degree for free on the Internet. That amazes me.

yeah -- using soem kind of data to map a user on a line is a pretty basic starting point.
.
but in the case of recomendation enginers, there is a lot of "guesswork".
.
if you want to look back at older "AI" tools, you can probably find some interestign information on chess-playing algorithms -- in general the "suggess" of those algorithms is to have a way to "score" the current state of the board, and then run down a tree of various moves/counter-moves to see which produces the best score. Some of those algorithms got pretty interesting back in the 8-bit computer days (where the chess-playing computer was (generally) slow, and limited resources.
.
but generative AI is (at least in part) similar to both examples - as you can generate sentences (suing "noun", "verb", "adjative", etc...) -- but as your language expands, you need to link words to the topic ( "keyboard" could be a musical instrument, or a "office" device) -- even digging through data sets (name 3 insruments which use keys) - requires you to rank all the instruments you know by their connection to "keys" -- so "piano" has keys ... and an "accordian" has keys ... a trumpet or clairinet (sorta) has keys (but they aren't called keys...)

According to my password manager, I made an account at the end of 2023, but my password also used characters that aren't allowed anymore.

Online courses don't quite count as a college degree. (Not necessarily accredited either.) But I'm sure the instructors enjoy putting up recorded lectures, never having to lecture the same topic next semester, and answering questions students have.

I had thought the chess playing algorithm was essentially bruteforcing every possible state of the board.

I didn't realize users can no longer log in with old passwords from 2023. I have added looking at this to my to-do list. I have sent you a private message about this also.
