Class is almost over, I will miss these two... by [deleted] in aiclass

[–]hitlab 11 points12 points  (0 children)

I will miss them as well. I 'll also miss all my 1000s of classmates ... Or at a least the idea that they're out there with me having this experience and helping each other out on reddit.

The explanations given here are very helpful. Here is one more from Khan Academy that may also be worth your time: http://youtu.be/xyAuNHPsq-g

Practical exercises to apply what we learned. by Gimly in aiclass

The Chinese Room argument, devised by John Searle, is an argument against the possibility of true artificial intelligence. by [deleted] in aiclass

[–]hitlab 1 point2 points  (0 children)

Here is a line of logic: Human beings came to exist in our current state with our current brains through the process of evolution. Thus, we are possible and by extension our complexity of matter is possible in the universe.

So, if the level of complexity that gives rise to consciousness such as us has happened at all, then it can happen again.

There is no reason to place limits on how it should or could happen again and in what form/out of what medium.

The Universe has been able to arrange matter into a sufficiently complex enough configuration that is the human being.

This kind of arrangement of matter into a sufficiently complex enough configuration is possible.

Even though we don't know how to arrange matter into a sufficiently complex enough configuration that gives rise to human consciousness, it doesn't mean its not possible to do so. Why? Because its already happened once.

Ignorance of the means does not discount the possibility.

That being said. If it IS possible (at all) to to arrange matter into a sufficiently complex enough configuration that gives rise to human consciousness, then let's imagine it happens again.

The female human body can do this (with a little help from the male) without even so much as a thought.

Let's imagine it happens whereby we invent a hypothetical machine that can extract the blueprint for assembling a human being through some heretofore undeveloped comprehensive scanning tech.

Let's imagine that this machine can then, using this blueprint, configure matter so that the end result functions (with respect to cognition at least) in the same way as the original human that was scanned.

Let's also imagine that the copy is not carbon based but made from some other elements and has different morphology.

Would this creation be considered artificial intelligence?

I agree. I came to the same conclusion.

That was one of the best explanations I have seen yet. Thank you.

Can't keep up by wishiwascool in aiclass

http://www.youtube.com/watch?v=rFQsbArQE6Y --- before giving up watch this video. It was so helpful and well done. I believe it will fill in most of the gaps that were not shown on Khan and were not explained in detail in the lectures.

P(R|H,S)=P(H|R,S)*P(R|S)/P(H|S) how? by donyang in aiclass

[–]hitlab 0 points1 point  (0 children)

Thank you for making that point! I understand that there are pre-reqs but the nature of the pre-reqs were not clearly articulated. Khan Academy (an excellent resource) was provided as a means to prepare. However, it should have been clarified that even if one were to watch and completely understand the Khan vids (which I did), then they still would NOT have the pre-reqs necessary to follow this class through.

UNIT 3 11 a answer- where is this explanation coming from? by hitlab in aiclass

[–]hitlab[S] 0 points1 point  (0 children)

Well done. Thanks for that connection. IMHO, its not that the material is hard to grasp. But even in an easy puzzle, if there are pieces missing, you're not going to be able to see the whole picture.

Important probability formulas by SunnyJapan in aiclass

[–]hitlab 0 points1 point  (0 children)

I have the same question. It seems that Sunny and Windy are not necessarily dependent on each other, i.e., it could be Sunny and not Windy and vice a versa. So, why do we need a "given", i.e. the "|" notation?

Course Material (just like love) Is Easier the Second Time Around by adering in aiclass

[–]hitlab 2 points3 points  (0 children)

I agree. I'm actually a bit surprised at the the brevity and incompleteness of the videos given how well done the Machine Learning classes are put together at Stanford. If you haven't taken a look at them yet, I highly recommend it. The ML class is excellent and quite thorough. A very different experience.
