Go to the Stanford University class CS106B, at http://www.stanford.edu/class/cs106b/[^]
On that page, you'll find an explanation on Binary Search Trees. Even better, download the Course Reader on that site, and you'll also find an explanation on Expression Trees.

Hey guys & ladies (to be gender insensitive), a theoretical thought, if a computer program simulates the human brain very accurately, does that make the program self - aware?

currently it has not been achieved yet, but are programs that use sensory processing such as computer vision systems self aware?
|
|
|

Computers are as close to the human brain as earth is to the edge of the universe. Don't take any notice of science fiction scare stories about computers magically becoming "self aware": it will not happen.

but the brain uses some form of neural computation to generate self awareness don't you think that anything with short term memory is self aware? Imagine we erase some part of ones short term memory, is he/she going to know that they did what they just did at that moment?

What does that have to do with computers becoming self-aware? As I said before you cannot compare the two, a computer is nothing at all like a brain.

Yes for now one cannot compare the computer to the human brain, but in the future there will be need to do just that, especially when the Fifth generation computers fitted with sensory processing programs come into existence, anything with self monitoring capability and short term memory is self aware, so a program that can monitor and keep track (learn) of it's actions is self aware, so short term memory as something to do with self awareness, I respect your view on this matter, but my stance is that self aware is as a result of mere self monitoring and keeping a log of actions (learn) in a knowledge base.

No it isn't, it's just a program, and it's no more self-aware than a tin of baked beans.

so in your own opinion, what causes self aware in humans?

Humanity; what do you expect?

To me i think it is just a mere result of computations of neurons in the brain, and that processing can be replicated in a machine.

Not any machine that will be invented in your lifetime.

First, prove that we are. Are the characters in The Matrix (not the lead characters, but the ones who think they're going about leading "normal lives") self-aware? I think not.
Are you sure we're not just some virus, software, or a dream being had by some being? Can you prove that I exist and am not just some imagining you're having?

No proof for that I'am afraid, that's the reason why we should not rush into concluding that programs can't be self aware.

I don't think this is true. Is a goldfish or an ant self-aware?
|
|
|
|
|
yes they are.
|
|
|
|

I agree about a dog, a cat or a rat, even a mouse or a canary, but I don't know if an ant is self-aware. It may be just queen-aware. OTOH, an ant's neural system is small enough that we can simulate it, I think. I don't know of anybody doing this, though.

Yes even insects might be self aware, the problem here is that one cannot disprove or prove that they are also self aware. 
|
|
|
|
|
If you're already convinced, then why did you ask the question?
|
|
|
|

I was not sure the moment i asked the question, but after thinking about it and taking into consideration views from others, my view evolved and became more inclined to the fact that some programs can be or are already self aware.

My view is that awareness is mostly about associating a stimuli to a particular response. At least any program that associates a keyboard input to a particular response is aware of those key strokes. So a word processor is aware if a keyboard button is pressed, but to be self aware a program only needs to have some self monitoring capability such as a feedback about it's performance.

Not really in terms of "self aware", but it is "aware" of key presses when the system signals that a key press has been done. Two completely different definitions. It just sits there idling waiting for a keyboard press event to be triggered.
My idea of "self awareness" is one in which something can take care of itself without necessarily having interaction with something else. A word processor cannot and will not do anything until the user interacts with it.

Which still boils down to someone coding that capability.
Looking through this entire thread, there are a lot of interesting points made by everyone...
