Something I thought about earlier today.... people always seem to be trying to make AI that are just like humans. They spend all kinds of time programming something that will learn everything it'll ever need to know in the same way humans learn.

But computers are much more powerful than the human mind. Even though computers don't yet think on their own, they can still do complex calculations and look up word definitions in nanoseconds (or the speed of your Internet connection if using web sources).

So, instead of trying to simulate a human mind that will have to learn and remember, why not stop building from the ground up and just give it the full credibility of being a computer?

For example, give it the ability to use its internal calculation algorithms instead of wasting time teaching it math like you'd teach your 5-year-old. A group of eggheads could get together and pour as much knowledge into the bot as they can possibly think of.

THEN, on top of that, the bot could then use its normal learning techniques to learn new things. It will have the added benefit of using all the resources on their computer, and it will still be able to learn things that their creators didn't even know.

Just my thoughts on the topic. Wink

I have to disagree with most of what you say.

First, the reason that we are trying to make human-mind-like AI is because we want to know how and why the human mind works the way it does, how we learn, reason and make decisions.

Second, you have it backwards: human minds are much more powerful than computers. Computers are faster in their ability to "crunch numbers", but that doesn't make them smart. Just being able to add, subtract and multiply fast does not make you a mathematician. Certainly, we have created computers that can beat any human in chess, but they use brute force, they don't know what they are doing or why and they were programmed by humans for this specific task. The human chess player does not use brute force, he simply "knows" what lines of play to avoid, he learns how to play by himself and he can do a million other things than play chess.

Third, looking up word definitions fast does not make you smart. Humans don't need to look up definitions for 99% of the words they know, because they have assimilated their meanings.

Fourth, what are the bot's "normal learning techniques to learn new things" that you talk of? Computers don't have any normal learning techniques. If you plug a computer in, it just sits there, it doesn't know how to learn. Sure you can teach it to lookup word definitions ad infinitum and do math every millisecond of the day, but it has to be taught how to learn.

The "normal learning techniques" I mentioned are the kinds of things we work on now. Like your A Word Experiment, its methods of learning (or possibly other methods of learning).

But if the bot has lots of built-in knowledge, but then still has the ability to learn more and fill in the blanks in its brain... it might be better off, since it wouldn't take so long to learn.

For example, in many of the movies and stuff about A.I. (well particularly I, Robot) they already have all kinds of built-in stuff, and then can learn still.

I dunno, these are just my thoughts. Although maybe I could've sorted them out better before starting this topic. Laughing

In my humble opinion I think its a bit like sitting next to a cat, and telling it about Landmines... and expecting a positive response.

Yes, but it would be cool to just go home from school/work, go on a messenger service and destress away chatting about it while not actually telling anyone anything.

Maybe you should get yourself an Eliza bot. Lots of my Eliza's bots users tell it all about their problems. Razz I wonder if they know they're being logged though.
