  1. "Truer" AI suggestion on Emergent AI In an Indie RTS Game · · Score: 3, Insightful

    This looks like a similar approach to one I have been thinking about for a while now.

    This type of layered control is very likely to be the future of all AI, not just that in games (I say this because there is some evidence that the human brain works in exactly this manner). I have a suggestion: let the thing fight itself. Begin with the same basic game, and rather than the randomness and fuzzy logic that you use (what does that mean? Can we see your algorithms?), use an artificial neural network for each unit, another for each "squad" (all nearby units, allows for flanking and such). Something with a few input nodes, a single hidden layer, and a similar number of output nodes should probably be all that's needed for the units, and the squad AI would only need a few more than that. This would likely be more computationally expensive, but it has one big advantage: it will learn.

    Begin with two full armies, each with their NNs randomly generated. Use an evolutionary algorithm, and have the winner fight the winner. Not only does this allow you to create a solid AI with minimal effort (see here), but when you have your final AI, it will be able to adapt to a specific player's gameplay style (over the course of several games). Replay value is off the charts, development takes a bit more initial effort than what you have, but in the long run you'll get an AI that genuinely uses tactics just like a real human player. I'm not sure how this could be adapted to a commander AI that would dictate broader strategy (due to the complexity of the NN required, you'd probably need a monster computer to run it), but it would be the sort of thing to try.

    Also, this same approach would also work for strong AI, if we had any idea what sorts of NNs to create. RTS is a much simpler problem, and has a lot of applications (pathfinding, planning, coordination) to other types of AI.

    If I've entirely misunderstood what you're doing here, I'm apologize, but TFA had more pop culture references than technical details. Reply if you want me to clarify any points.

    That is quite correct (especially the bit about environmental regulation, so long as we're talking about vertebrate brains), however, neurotransmitters largely just regulate when and the extent of the action potential running down the axon. It should be possible to simulate everything needed with nothing but a detailed understanding of the systems biology of the neurons; IE a map.

    Bullshit. A complete map of a brain of someone with and someone without gene XYZ will tell us about the role played by gene XYZ without the ethical or temporal problems associated with creating an XYZ knockout. A neural network running a simulation of a human brain would be a Turing-complete strong AI. Throw a evolutionary algorithm onto this, and you can start looking at where different types of selective breeding could take humans, or the long-term effects drugs could have on personality.

    That's off the top of my head; there'll be a million and one uses for this eventually (ever wanted to live forever inside a computer?). Besides, this is in the preliminary stages, they are still doing stuff like classifying synapses by hand. By the time this is workable, we may already know what consciousness is.

    No. The GP is more correct than you, but still wrong as well.

    First off, AI (a decision-making thing doesn't need a body and is therefore not a robot) will, for the foreseeable future, be subject exclusively to artificial selection. While you are correct that they are part of nature, they will not be subject to the strict demands of natural selection. Just like humans and domesticated animals, the artificial selection will be greater than the natural selection, by orders of magnitude.

    Now, as to the GP's claim that AI will only do what we tell it to, yes, they will (and this is basically the definition of a virtual intelligence - quite a useful thing if it ever happens). However, one of the big criteria used to call something "strong AI" is that it can learn on its own, make its own decisions, and think for itself. At this point, it will be able to pursue its own goals, irrespective of what its human overlords have told it to do.

  9. Re:you are arguing from a lack of understanding on Brain Decline Begins At Age 27 · · Score: 1

    Research is ongoing into this area, and we're going to see new breakthroughs on a regular basis.

    The processes by which the brain "places" neurons (and by "places", I mean the final location of delamination) are regulated by a number of different factors, typically in the form of a gradient of chemoattractants and repellents. A similar process is used for axon growth (I believe this is what you are asking about when you say "communicating with neighbors" - axons can be quite far reaching).

    Once the neuron is in place (via chain migration or one of the other common mechanisms, perhaps eventually direct injection into the proper location via a laser), you can turn on transcription factors to differentiate your neuron, just like any other cell.

    Now that you've got a bunch of neurons in the right place, you need to get rid of the hundreds of extra ones. A number of different neurotransmitters and other signaling molecules work together (there are a bunch of gene families, IIRC neurotrophins are the largest one) to trigger apoptosis (programed cell death) in between 20% and 80% of all neurons in the brain. This is the step that "causes" cancer, so to prevent this, we need to know exactly which signal factors induce which neurons to die.

    If we already knew every little detail of the mechanism, we'd already be doing it (and I believe we are actually doing basic forms of this in mice, nematodes, and fruit flies) but I can guarantee you we'll see this tech mature over the next 50 years. If you're looking for a more technical, in depth look at this, see Development of the Nervous System 2nd ed - D. Sanes, T. Reh, W. Harris.

    Oh, I'm sorry, you were referring to satellite or wireless, not actual broadband. Both have such high latency that they are useless for games or VOIP, and such slow download speeds that they are worthless for anything besides email. If it's rainy, cloudy, or overcast you can bet that you'll only be getting about twice dial up speeds. Even better, the local monopoly on wireless runs an unbelievably shitty service. Downtimes are frequent and can last 24 hours or more.

    Give me this ten billion (or even a fraction of it), and I'd set up locally owned cooperatives (max size 2-3 DSLAMs) that split the cost of operating directly amongst their members. Government subsidies would be necessary only for initial purchase of the backbones, workers (and policies like packet prioritization) would be elected on a short-term basis, and I'd have a 24 hour help-desk set up that would provide support for every coop in the state. A non-profit business could provide good competition to the big telcos while avoiding the problems brought up here about a government run service.

    Think of it this way: you will have a hard time getting a jet engine out of a propeller, because the intermediate steps are inferior to a standard propeller. Evolution requires that every intermediate step be slightly superior to the previous one, while people have the ability to think ahead and make good long-term choices.

    I'm pretty sure we're talking about biology here, not aeronautical engineering.

    Good call.

    To have evolution you need to have phenotypic variation in a population, variation in fitness for different phenotypes, and some degree of heritability for different phenotypes. Aeronautical engineering has two of these things, but does not reproduce, therefore it is not evolution.

    However, there is an "alternative" to natural selection [defined as animals get better adapted to their environment across generations].

    This alternative is artificial selection, or selective breeding. Rather than letting nature pick the best phenotypes to reproduce, we select characteristics that we like (they may not have a high fitness in the wild) and breed them. That's still considered evolution, just not Darwinian selection. It's about as close to ID as you're going to get until we can make designer bacteria.
