Lecture 14: The Turing Test - Richard Buckland UNSW

[jhamien920]

I'll be watching more of Richard's video. he is so funny at the same time informative.

The Postmodernism Generator is a computer program that automatically generates postmodern essays. Gramatically correct but meaningless.

Now watch a college language student reviewing a computer generated essay. He has no clue of its true origin.

A must see.

[annihilatedsin]

what's the name of the book he mentioned? I can't understand him...

[barramundi9]

@annihilatedsin  The name of the book is "godel escher bach".

30:35 If anyone is curious:

"argc" is how many arguments you are passing to the program(an integer number), and "argv" is a single array of (chararacter) pointers to the strings which are those arguments. The details are hidden but these arguments are passed to the program via your system's command line interpreter.

Google: "The C Book - Arguments To Main" if you want to learn more. You won't really use it for Windows environment, it's a command-line environment thing.

[wvragga]

I also am trying to make out the name of the book he recommended we buy....

please help if you know the title...thanks!

[Shorty20122012]

What was the book he referred to about artificial intelligence?

[faunflynn]

The Turing test is based on the philosophical principle of indiscernability.

"If they look and act the same they are the same, for all intents and purposes or those in tents and porpoises.

But, and it's a big but. What about the Chinese room hypothesis ?

[faunflynn]

THis lecture gets better the more I listen to it.

Kudos Mr Buckland. Wish my teachers had been like this, ie. Enthusiastic and SMART, Whip sharp mind and compassionate to boot.

Great stuff !

[faunflynn]

By the by, the Turing test doesn't work.

A simple A.I. can do a good impression of a human.

[alanzeino]

@faunflynn so why hasn't a single 'A.I.' passed the test?

[faunflynn]

@alanzeino As yet you are right it has not been done, BUT. To do an impression of a human does not require sentience. See Milgram's cyranoid experiment.

This has been tested by people following rules, imitating a hypothetical, as yet none existent AI. It was very rigerous. Oops, cnt spl.

the point is , when people think we have AI's we may very well not have.

The true test of an Ai is not playing human but being transhuman.

Sorry if I said this badly.

[faunflynn]

@alanzeino A better answer is that as yet we have nothing even approximating AI.

To test the logic of such arguments we have to use artificial, artificial Intelligence.

Oddly enough AAI is a growth industry. Sad cuz it treats people as parts of a machine.

Like working in a call centre. Beats working in a mill at 6 yrs of age I guess, but alas sweat shops are still rife the world over.

[faunflynn]

The particular men's loo that lead to Turing's trouble is still there. There's a pub frequented by people into heavy metal and goths behind it. It's beneath a vast railway arch just down from the Uni. Beside the point I know,but not utterly without interest.

Turing was my hero since '76.

Great post , rock on Mr. Buckland.

[subzerohackmaster]

Beautiful, just beautiful. I wish I could get the opportunity to go to this school.

[intindse]

theres xcode for windows?

[brickbat14u]

Regarding Turings sexuality & the 'thanks UK' comment. In the context of post war, the hysterical antipathy towards homosexuality generally was common place throughout ALL Anglo saxon nations and that includes Aussies. Nobody is clean on this one. Also ENIGMA was important and Turing did help to devise a system for cracking it but is was essentially an electro-mechanical device...not a computer! The real computer was called COLOSSUS which decoded the Geheimschreiber codes (teleprinter)

[UNSWelearning]

too true sadly about australian conservatism. had oz had a gay war hero of such great contribution they could well have been persecuted also. but that in no sense excuses the utterly shameful treatment he received.

mechanical or electric makes no difference as to whether it is a "computer" (indeed the theme of this lecture!) eg babbage's analytical engine was more a computer than colossus was. turing contributed to the automation of computation but did not build a computer at bletchley park

[bighands69]

@brickbat14u

A computer is not a physical device. It is conceptual mathematical machine.

Any system that uses mathematics is technical a computer.

Computation is a mathematical concept with definable rule sets.

[username1354982]

Just to clarify this isn't a criticism of the philosophy, but the example implementation.

[username1354982]

"So closely" is the flaw in the Turing test. The test is EXTREMELY limited in scope and thus the measure of closeness cannot be inferred. Inferring closeness from it is a mistake. It would be like saying: According to a measure of height alone this rock is as tall as this human, therefore this rock is a human, because of how closely matched they are.

[beerbelly777]

your analogy only includes one measurement. The actual definition of a human would include many measurements, so to test the rock, you would have to apply every measurement to the rock which define the human. undoubtedly, you would end up concluding the rock is not human...your argument is kind of a strawman argument.

Thanks for uploading the audio clip :-)

[travisSimon365]

@tverwaes: he knows that it is legal c code, but he's saying that it is not allowed int the course.

[tverwaes]

Nice lectures! Just one comment on this one: you can use counter++ as a value as well. It is a postcrement so it will return the original value while setting the counter to the next one. ++counter would return the new value as it is a precrement.

[joidimo]

I think what he means is that the students are not allowed to do that because it's bad programming practice and, generally speaking, produce code that is error prone and hard to follow.

[acropetalsentient]

regarding the Philosophy T:

What's the difference between a good, altruistic person, and a selfish person who does good, altruistic actions all the time?

there isn't. You wouldn't be able to tell the difference. so:

what's the difference between a human that answers all his questions from a certain worldview, and a computer that answers all of it's questions from the same worldview?

there isn't any differences here either.

[devjock]

The idea of self awareness (is that valid english?) could be explained nicely by watching "Terminator: The sarah Connor Chronicles".

Season 2 explaines nicely how a computer could rise to be self aware. (although in a dooms-day scenario)

Very good lecture!

[sigilalias]

thanks for this video...

at the end a student ask if there is souch a thing as x code for windows, and the teacher anser yes, and the video stops, does enyone remember what he then ansered?.

[kbat82]

maybe netbeans or SciTE. You will probably need cygwin also. All of these are free but somewhat tricky to set up in my opinion.
