Answer» Hello, Humans still do not really understand how living things deal with information. What do you mean? Deal with how? Quote from: luck of the irish on September 26, 2011, 09:24:03 AM Hello, How does a bacteria CPU work? What do you think about quantum computers? Quote from: JJ 3000 on September 26, 2011, 10:36:19 PM What do you mean? Deal with how?A frog sees a fly. His sticks out his tongue and catches it. How did he know it was a fly? how did he MEASURE the distance?How did he estimate the SPEED and direction? How did he co ordinate and correct the trajectory of the tongue? Was most o0f the process in his central nervous system? At a high or low level? Did he really make a decision? Was it all automatic? What if he was not hungry? Presently, it is believed that some of the process is done in the eye itself, and not the brain. It that be true, could d we be working on smarter cameras instead of a better CPU? The smart eye of the frog lets him live with a cheap CPU. The "smart eye?" Instincts are hardwired into the brain, not the eye... The frog in question is exhibiting a fixed action pattern-evolution has DETERMINED that FROGS which stick their tongues out at flies are going to gain more nutrition than those who don't. http://en.wikipedia.org/wiki/Fixed_action_pattern What does this have to do with computers, which were created to serve humans? Quote What does this have to do with computers, which were created to serve humans?Depends. If the behavior is very simple, it would be of limited use. But the behavior of the frog has many variables as inputs. That is the area of interest. That ability if applied to man-made machines could allow you to drive your car on auto-pilot on a busy four lane highway. The automobile itself would instinctively brake, accelerate, swerve and curse the car that tried to cut in front of you. And it could read the road signs and make decisions about when to change lanes for the next exit. All by instinct. No thin king ability.Right, but the term "automobile itself" would not be valid, as the term instinct applies to living things, i.e. something which is composed of cells and has nucleic material and a form of reproduction. This is just cause and effect. Computers are just machines, not entities. I doubt you could program a computer to feel hurt with today's programming languages and hardware. Computers are merely gateways to human knowledge. Quote from: Geek-9pm on September 27, 2011, 12:42:43 AM Depends. If the behavior is very simple, it would be of limited use.Yes. Computers function based on logic gates. We can arrange logic gates in different ways to get a desired output. A simple yes or no. We can program a car with a radar system to detect the presence of an upcoming barrier-the gas/brake pedal is adjusted as a result.

I doubt you could program a computer to feel hurt with today's programming languages and hardware. I don´t believe that any computer of whatever technology past present or future can have mental contents by definition. Quote from: Salmon Trout on September 27, 2011, 02:44:25 AM I don´t believe that any computer of whatever technology past present or future can have mental contents by definition. That depends on what computers will comprise in the future. After all, in many ways, animals are merely a sort of biological machine. Quote But the behavior of the frog has many variables as inputs. That is the area of interest.You realize that the sort of thing you are talking about is pretty much equivalent to fuzzy logic and is implemented in automatic produce sorters and other devices designed to automatically grade manufacturers or harvested products? It's really no different; for a frog, either something it sees is food or a threat to be considered. Almost any small flying thing is going to be something it can eat. And of course, as Transfusion noted, there is a inscribed pattern that the frog "looks for" instinctively, to identify it as food. After identifying something as food, the autonomic nervous system takes over. In fact, one might consider that a frog, or in fact many animals of it's sort, act purely on autonomy, and don't have self-awareness, which is of course an entirely separate topic when speaking of Artificial intelligence. The fact is, "instinctual" or automatic behaviour, already exists and takes place with computers; even if the analogy is a bit drawn out. We don't generally think about breathing or our heart beating or the exact muscular movements required to walk, run, swallow food, chew, etc. We basically just walk, run, swallow and chew; whether this is as a result of already known behaviour (born with the knowledge of how to swallow/chew/etc) or whether we learn it via "training" is additionally irrelevant, because the fact is that how it got there isn't really relevant in this context. What is important is that it is there and we don't need to waste much conscious thought on it. For a computer, obviously this is still true to an extent; of course, computers aren't concious, don't have thoughts, etc. In fact the closest thing to a conciousness a computer has is the user itself, and in that context, the user doesn't have to do anything special to make sure that the CPU clock keeps ticking, or that the memory is refreshed, or that Bus mastering is properly handled by the chipset, since that is all done automatically. Higher-order functions, such as, say, combining two AVI files together or presenting a UI to allow for word processing, can be "trained" into the computer via software; at which point the user (again, using the drawn out and mostly invalid analogy of the user as the computer's consciousness) can engage in word processing without thinking of the particulars of how fonts and text are rendered, leaving that to the "autonomy" of the system. Quote That ability if applied to man-made machines could allow you to drive your car on auto-pilot on a busy four lane highway. The automobile itself would instinctively brake, accelerate, swerve and curse the car that tried to cut in front of you. And it could read the road signs and make decisions about when to change lanes for the next exit. All by instinct. No thin king ability.WOW! You mean they can do things that have already been in the AI of Racing and other games for years? Amazing! Of course I wouldn't trust most implementations on the road. But it's not like it's some farfetched goal. It's already possible on the software level, there is simply no point and no profit in implementing it in reality.Frog Eye Bionics Electronics: Man-Made Frog's Eye |
