AI Experts In High Demand 78
An anonymous reader writes: The field of artificial intelligence is getting hotter by the moment as Google, Facebook, Amazon, Microsoft and other tech companies snap up experts and pour funding into university research. Commercial uses for AI are still limited. Predictive text and Siri, the iPhone's voice-recognition feature, are early manifestations. But AI's potential has exploded as the cost of computing power drops and as the ability to collect and process data soars. Big tech companies like Facebook and Google now vacuum up the huge amount of data that needs to be processed to help machines make "intelligent" decisions. The relationship between tech giants and academia can be difficult to navigate. Some faculty members complain tech companies aren't doing enough in the many collaborative efforts now under way. One big gripe: Companies aren't willing to share the vast data they are able to collect.

The term "AI" dropped out of favor a decade ago as a result of a lot of over-promising and under-delivering from the decade before that. Remember "expert systems"? Yeah, that was "AI" in a different guise. It looks like the term "AI" is making a bit of a comeback. I'm not sure that's a good thing, because it never really describes these systems adequately, as "intelligence" has very little to do with it.

I'm not sure where you got this information, but as someone that studied Artificial Intelligence in college (in the 80's), I can assure you that Artificial Intelligence has been around far longer than Expert Systems.
Expert Systems are usually considered one of the first successful forms of AI, becoming of practical use in the 70's, and then proliferating in the 80's.
But Artificial Intelligence as a field has been around since the 1950's.

Exactly.
Besides, the first entity that gets a functioning superhuman brain, if it has enough lead time over its competitors and is able to gain enough data and indoctrinate goals, is very likely to win. This applies in every field of human endeavor. Think of the enormous transaction and synchronization costs we have to deal with in the incredibly inefficient networking between your brain and mine, for example.

That's a pretty-good description of what an *adult* brain does, but it's not a good description of intelligence - artificial or otherwise. Your adult brain learned the rules from its environment with no assumptions about what those rules were.
Try writing an algorithm that can learn to play either chess or checkers, depending on what game it sees.
Make that same algorithm be able to play asteroids, or drive a car, or OCR.
Make that same algorithm be able to recognize a tune ("row row row your boat") even if it's played in a different key, at a different speed, with variations in tempo, and even variations in key.
Any time you know beforehand what the rules are you are not simulating intelligence - you are simulating the *results* of intelligence. You are just writing down whatever it is that the intelligence in your head has decided.
The intelligence never makes it into the program - it stays in your head.

Many modern AI methods take advantage of unsupervised learning. Not only do they not need to know what the rules are, they don't even need to know the right answer most of the time. There are successful demonstrations of such algorithms learning to play Nintendo from watching people play, and Google's deep learning network learning the concept of "cat" from watching YouTube videos. I also remember a paper looking at recognizing melodies played in different keys.

Excellent explanation. The brain certainly has some automated components that are not intelligent and they are configured by actual intelligence as you describe.

The formal logic approach is still the only one that has a theoretical possibility of creating some aspects of true intelligence. Unfortunately, in this universe, it fails even at small problems due to limited computing power available. The brute-force approach is good enough to simulate very limited intelligence when an incredible lot of data is available. That has nothing to do with intelligence though, and statistical approaches cannot simulate more complex chains of reasoning. They are always shallow. O
