<p dir="ltr">So if I told you to write a loop where you start with an array of numbers and multiply them all together, printing out the result at each step (as in, print the first number, then the first two multiplied together, them the first three, and so on until you reach the end of the array), you could at least picture roughly how to do it, and you wouldn't be totally lost, right?</p>
<p dir="ltr">> As far as statistics, I can do factor analysis (and don't trust it too much), analysis of variance, and particularly regression analysis, as well as all the lower things. All in a people experiment context.</p>
<p dir="ltr">So let's say we had two conditions, A and B. We've measured a series of events, and noted how many times A occurred without B, how many times B occurred without A, how many times both happened, and how many times neither happened. Would you be able to plug in the numbers for Bayes' theorem, P(A|B) = P(B|A)*P(A)/P(B) ?</p>
<p dir="ltr">If both of those are true, then you have the basic knowledge to understand how modern AIs work. If either one is not true, that's a topic you'll need to study up on.</p>
<p dir="ltr">> So I want to understand AI from a psychologist's point of view. Are we trying to teach them how to think like us? DO they?</p>
<p dir="ltr">First define how we think.</p>
<p dir="ltr">They are coming up with algorithms that lead to useful conclusions. It is true that we are capable of following those algorithms too, if far more slowly (at least when we do so consciously, as opposed to subconscious things like visual pattern recognition and edge detection) - after all, we dreamed up those algorithms.</p>
<p dir="ltr">But do those algorithms reflect how we think, day to day/most of the time/in practice? That is more the realm of neurobiology than AI.</p>
<p dir="ltr">> People are so fuzzy and complicated and most things are centered around probability, whereas AI seems so cut and dried and one answer and no probability.</p>
<p dir="ltr">Ahahaha, no. AI is largely about probability.</p>
<p dir="ltr">Now, there may often be one answer that is so far more likely than any other that there may as well be only one...but surely you have encountered many such situations too. If you are driving a car and you have entered a parking spot at your destination, is not the usual best - and practically only - answer to apply the brakes and stop, even if the answer could sometimes be to reverse and leave (if you then notice it's a handicapped spot, or if some bat-wielding parking spot protector then starts yelling and running at you)?</p>
<p dir="ltr">> But likely it is as complicated as the computer in Pratchett's Discworld where you get 'OUT OF CHEESE ERROR" that no one understands.</p>
<p dir="ltr">That comes from a different type of programming: the traditional non-AI where all logic was discovered and implemented by humans...who sometimes labelled things badly, such as calling a certain type of transitory memory "cheese" because they were thinking of cheese when they wrote that memory manager.</p>
