All species in which cerebellar and/or cerebellar-like circuits have been reported are motile and sufficiently large that their kinematics is influenced by inertia, and they interact with other ... 09:23 < kanzure> ... such animals. Inertia constrains how the kinematic state (position, configuration, and rates of change) of an object changes as a function of applied force, such that, if an object has inertia, then information about its kinematic state can be used to predict its future position and configuration at least in the short term.

The fact that this group includes disparate, unrelated species indicates that the genetic and developmental capacity for cerebellar(-like) circuits may be shared by all animals with nervous systems and that it has been co-opted by evolution whenever ... 09:23 < kanzure> ... there has been an ecological opportunity for animals capable of dynamic motion prediction and control [69]. More generally, the ability to predict state trajectories of dynamical systems from observations provides a core capability that may underpin a wide variety of perceptual, cognitive, and motor tasks [70]." 09:24 < kanzure> "Until a few years ago, the Kalman filter was the only known practical algorithm for dynamical state estimation [71]. It assumes linear target dynamics, an assumption that does not hold for mechanical linkages like human and animal bodies. Newer algorithms based on drawing random samples from probability distributions defined by observations are able to track states of high-dimensional nonlinear systems [72]. These algorithms can be ... 09:24 < kanzure> ... implemented using spiking neurons, in which a spike at a particular location in a network represents a sample at a particular location in the state space of the system tracked by the network [73, 74].

The problem with AI is that it would want to do that 11:34 < Diablo-D3> the problem is not AI winters happen, but soon as a technology starts working and everyone integrates into their products, it stops being AI 11:34 < esmerelda> I thought HBP was a giant boondoggle 11:34 < kanzure> Houshalter: humans want to blow up the earth. i'm one of them. 11:35 < esmerelda> Diablo-D3: tell that to the expert system programmers 11:35 < Houshalter> kanzure, well they've been really bad it at so far 11:35 < kanzure> Diablo-D3: that's fucking absurd. how about instead of claiming "AI stops being AI", how about "people were wrong to call these things AI". duh? 11:35 < kanzure> oh my god i hate all of you so much 11:35 < kanzure> this is why the planet needs to be blown the fuck up 11:35 < Diablo-D3> kanzure: well, thats honestly what Ive been saying 11:35 < Diablo-D3> but I get yelled at when I do that 11:36 < kanzure> Diablo-D3: no, you just said the opposite. don't lie to me. 11:36 < Diablo-D3> kanzure: yes, because people don't bitch when I say that 11:36 < esmerelda> kanzure: do you want to blow up the earth before we save a backup? 11:36 < kanzure> you were hanging out with the wrong people, and it shows negatively on you that you didn't recognize this 11:36 < Houshalter> kanzure, wtf 11:36 < Diablo-D3> kanzure: yeah, but somehow I'm wrong if I say everyones the wrong people. 11:37 < Diablo-D3> at least 90% of the human population may, in fact, be too stupid to live. 11:37 < kanzure> Houshalter: i have no idea why you are less interested in humans blowing up the planet. 11:37 < Diablo-D3> I'm the bad guy if I kill off 90% of the human population. 11:37 < kanzure> esmerelda: no i don't think so. there's good science in there somewhere. 11:37 < Diablo-D3> So, w/e 11:37 < Diablo-D3> if I want social interaction with normal people, I phrase it as "it stops being called AI" instead of "it probably wasn't AI to begin with" 11:37 < kanzure> Diablo-D3: "AI stops being AI when it is integrated" has nothing to do with killing off 90% of the population. thanks. 11:38 < Diablo-D3> like, people call google now and siri AI 11:38 < Diablo-D3> I don't know why 11:38 < Houshalter> kanzure, because i'm not a comic book villian? 11:38 < Houshalter> and i want to live 11:38 < Diablo-D3> they're just highly advanced natural language parsers 11:38 < esmerelda> kanzure: also if you could use something like radiation instead.. the rock formations and rivers are pretty 11:38 < Diablo-D3> using an incredibly huge database of knowledge 11:38 < kanzure> Houshalter: i didn't say "you personally interested in acting to blow up the planet". you are clearly interested in AI blowing up the planet. so why not humans? this is absurdly hypocritical of you. 11:39 < kanzure> "they are bad at it so far" applies to both humans and ai, anyway. 11:39 < esmerelda> The kolgomorov complexity of this conversation is rather low 11:39 < kanzure> esmerelda: perhaps you could clarify what you mean by boondoggies then... 11:39 < Houshalter> kanzure, ok that was worded confusingly. but yes I agree humans could blow it up, but they don't want to. And even if we had a coordinated program to put a nuke in every city, there would still be survivors 11:40 < kanzure> Houshalter: yeah i was thinking of doing a paper about the surprising difficulty of killing all humans. thankfully, blowing up the planet does not require killing all humans. 11:41 < esmerelda> kanzure: I read criticisms of the HBP by neuroscientists who claimed the hardware they were building was not necessarily well suited to meaningful simulation of a brain 11:41 < xentrac> .g the energy cost of evaluating earth's human population kragen-tol 11:41 < yoleaux> http://library.sandiegozoo.org/news/2015_news/2015_04cd.html 11:41 < Houshalter> nuclear war hasn't happened so far, and no one wants to start one. Even a nuclear war only destroys the countries involved, not the whole planet. 11:41 < xentrac> .g the energy cost of evaluating earth's human population "kragen-tol" 11:41 < kanzure> esmerelda: did you read the rebuttals by any chance? 11:41 < yoleaux> No results found. 11:41 < kanzure> stop stealing that kragen guy's work, man 11:41 < esmerelda> Kanzure: no, only one article. I said that I thought it was a boondoggle, not that it is in fact a boondoggle. 11:42 < kanzure> Houshalter: i think that nuclear blasts in cities would not be enough to blow up the planet 11:42 -!- sandeepkr [~sandeepkr@111.235.64.4] has joined ##hplusroadmap 11:42 < Houshalter> I believe AI is by far the greatest risk to the world 11:42 < Diablo-D3> sure thing Elon. 11:42 < esmerelda> I meant to imply this was my default viewpoint given limited data, and I don't hold it strongly 11:42 < kanzure> esmerelda: then i would suggest your current understanding is highly biased by detractors :-) it was a $1 billion project and a bunch of people were angry about not getting a slice of the pie. 11:42 < kanzure> esmerelda: there's a bunch of interesting neurophysiology that markram's group incorporates into their work 11:43 < kanzure> esmerelda: http://diyhpl.us/wiki/transcripts/markram-2006/ 11:43 < kanzure> xentrac: what does "evaluating" mean here? 11:44 < esmerelda> Kanzure: this is interesting, thank you. I should probably use more clear language when discussing opinions I've heard but don't espouse strongly, to avoid misunderstanding 11:45 < kanzure> there was no misunderstanding afaik 11:45 < kanzure> opencog, blue brain, then you mentioned you had read some criticism, something about boondoggies, then i gave you links or something 11:46 < kanzure> oh, boondoggies came first 11:46 < kanzure> yeah i didn't misunderstand that, i just mentioned there was good science in there somewhere 11:47 < esmerelda> Ahh OK. I thought you were talking about the totality of human existence 11:47 < kanzure> good science in human existence? perhaps :-) 11:47 < esmerelda> Hrm, I had a thought unrelated to all of this. 11:48 < kanzure> esmerelda: http://diyhpl.us/~bryan/papers2/neuro/ 11:48 < esmerelda> Say that we can store the data required to emulate a brain, but evaluation is very slow (E.g. 1 second per week) 11:48 < xentrac> um, evacuating 11:49 < xentrac> .g the energy cost of evacuating earth's human population kragen-tol 11:49 < yoleaux> https://www.mail-archive.com/kragen-tol@canonical.org/ 11:49 < xentrac> https://www.mail-archive.com/kragen-tol@canonical.org/msg00138.html 11:49 < kanzure> oh that makes more sense 11:49 < esmerelda> If you put that on a satellite and shoved it out into space, it would not feel slowed down and thus feel probably pretty happy 11:49 < kanzure> yes but it would have massive latency 11:50 < xentrac> that describes how you can blow up the planet without killing any humans. not that I think this is a good idea 11:50 < esmerelda> Sure, but maybe it's a hermit! Or you put 10 brains in there 11:50 < kanzure> right, there might be value in having a somewhat working biosphere 11:50 < TMA> Sometimes, I wonder whether we don't have a superintelligence already present. -- the world economy directs our decisions. moreover, in a sense, it has its own will, even though it is not an entity in the traditional sense 11:51 < kanzure> TMA: no, please see http://slatestarcodex.com/2015/12/27/things-that-are-not-superintelligences/ 11:52 < xentrac> the economy, corporations, states, etc., are superhuman intelligences, but they are not superintelligences 11:52 < esmerelda> Kanzure: why do you want to blow up the world though? 11:52 < xentrac> they are superhuman in other aspects like longevity and physical force, not in intelligence 11:54 < esmerelda> Given a collection of processors, I think a superintelligence must demonstrate that it makes decisions better than how good all the individual decisions of the processors are. 11:55 < kanzure> blowing up the world would be simpler than tolerating the low-level crap that AdrianG and Diablo-D3 inflict upon me in here 11:55 * esmerelda suggests /mute, or drugs 11:55 < kanzure> well i can also ban them 11:56 * Diablo-D3 rolls eyes. 11:57 < esmerelda> You could make this channel a more complicated variant of #xkcd-signal 11:57 < Diablo-D3> esmerelda: hows that work? 11:57 < esmerelda> so that similar statements or lines of reasoning are detected and cause muting 11:57 < kanzure> right, i would have to do that manually though 11:57 < kanzure> and i would rather that people voluntarily don't suck at all 11:59 < kanzure> xentrac: btw, evacuation is much easier if you assume working and useful brain scanning 12:01 < esmerelda> kanzure: if you trained an HMM on the chat logs here, and then for an input M computed the probability of producing M with the model 12:01 < kanzure> train the model on all the blocked/banned/kicked users? 12:01 < esmerelda> Then you divide that probability by the probability of producing any random sentence (mean probability) 12:01 < esmerelda> Sure, or even on all users if you want to avoid repeat topics 12:02 < kanzure> repeat topics are fine as long as users do due diligence or make an active effort to not be lame 12:02 < esmerelda> Then you'll need a training set of lame sentences 12:03 < xentrac> kanzure: yeah, if you assume the brain emulation hardware is lighter or more robust to space conditions than human bodies 12:03 < xentrac> and I guess cheaper 12:04 < xentrac> right now it's much heavier, much more expensive, and significantly less robust 12:04 < xentrac> and Moore's Law, which we were counting on to fix that, has ended 12:04 < kanzure> well..... you could bury the emulation hardware, and then blow up the planet, and then recover the hardware? 12:04 < xentrac> we'll probably come up with a different fix but it's historically contingent 12:05 < kanzure> we should bury satellites that get deployed when the planet inevitably breaks up 12:05 < esmerelda> Take the simple case: say that Diablo-D3 says "AI is dangerous". Let P(AI, is) = 0.7, and P(is, dangerous) = 0.9 in the model. Then he had a 0.63 probability of saying that statement. Then say that the probability is 0.1 for an average user, that a second model was trained against 12:05 < xentrac> what, when the sun cooks it? 12:05 < kanzure> well perhaps something happens sooner 12:05 < kanzure> maybe 12:05 < Diablo-D3> esmerelda: I wasn't the one saying it was dangerous though 12:05 < Diablo-D3> I was agreeing with kanzure that the article is trash and its wasting people's time 12:05 < esmerelda> I'm talking about signal detection 12:05 < xentrac> here's a sample non-stupid statement from Diablo-D3: 19:32 < Diablo-D3> Houshalter: okay so, I once wrote a bitcoin miner, it ended up becoming the world's most popular miner for gpus. 12:06 < kanzure> what, cgminer? 12:06 < xentrac> here's a stupid thing: 19:33 < Diablo-D3> I suspect more computation power is being spent on bitcoin than anything else. 12:06 < xentrac> dunno, you'd have to ask him 12:07 < Diablo-D3> kanzure: cgminer is a port of diablominer to C, with later added fpga and asic support 12:07 < esmerelda> Right, xentrac. But the system would compare the conditional probability of each transition given that Diablo-D3 said it, vs. the average probability over all users 12:07 < esmerelda> That tells you how "Diablo" a statement is 12:07 < Diablo-D3> ck undertook porting it to C to make fpga and asic support possible 12:08 < esmerelda> So the system wouldn't flag "Hi", but it would flag "bitcoin miner" (problematic) 12:08 < xentrac> but the bitcoin miner statement was actually a point in Diablo-D3's favor 12:09 < esmerelda> Yeah. I was just interested to see if I could design a system to censor certain topics or views 12:09 < xentrac> that shouldn't be too hard 12:09 < esmerelda> Diablo was just a hapless example (sorry, man!) 12:09 < esmerelda> xentrac: without much human intervention? Clearly you and I should make a startup for this 12:09 < xentrac> unfortunately a system to censor stupid or content-free statements about a topic but not insightful ones is much more difficult, probably AI-hard 12:09 < Houshalter> esmerelda, that just rules out all short sentences 12:10 < xentrac> Houshalter: that in itself sounds like a good idea 12:10 < Houshalter> how do you answer a yes or no question? 12:10 < esmerelda> P(yes|Diablo)/P(yes) ~= 1 12:11 < esmerelda> So it wouldn't be censored 12:11 < Diablo-D3> Okay so, what is considered the largest use of computational power of a single project? 12:11 < esmerelda> You know, maybe I should just go build this thing. It seems simple and fun 12:11 < kanzure> probably a hydrodam would count as a computation 12:12 < kanzure> *would qualify 12:12 < Diablo-D3> current hashrate is 9862 exaflops 12:14 < Diablo-D3> 9,862,475 petaflops, folding@home hit 25 petaflops in sep 2015 12:15 < xentrac> Diablo-D3: maybe the black hole at the galactic core? 12:16 < Diablo-D3> so what other projects out there can be measured at single digit zettaflops 12:16 < xentrac> Houshalter: you could say something more interesting than "yes" in response, although as esmerelda is pointing out, that wasn't actually what she was suggesting 12:17 < Diablo-D3> xentrac: thats not a computation project though =P 12:18 < xentrac> the #xkcd-whatever channel does in fact ban responses like "yes" 12:18 < esmerelda> Yeah. My system is different though 12:18 < xentrac> Diablo-D3: just because you don't understand what it's computing doesn't mean it's not computation. most people don't understand what their remote control is computing either 12:19 < xentrac> esmerelda: yes, I didn't mean to imply otherwise 12:19 < Diablo-D3> xentrac: I don't know what its computing, but I do know its an i.MX 12:20 < xentrac> Diablo-D3: are you giving me the model number for the black hole at the galactic core? you are a very silly sentient being. 12:20 < Diablo-D3> xentrac: sigh, no, my remote control. 12:21 < xentrac> maybe you might get confused and think that your remote control is also not a computer, as you apparently think about the black hole and about kanzure's example of hydroelectric dams 12:22 < Diablo-D3> xentrac: no, its very much a computer, it has a usb port and everything. 12:23 < xentrac> are you suggesting that the black hole at the galactic core is primarily lacking a USB port for you to recognize it as a computer? 12:23 < kanzure> oops it's not called a hydrodam is it 12:23 < kanzure> xentrac: to be fair, lots of bitcoin mining equipment is also lacking usb ports 12:23 < Diablo-D3> I'm not sure how either of those are answers to the question "what computing project uses the most power, or is in the range of single digit zettaflops" 12:23 < xentrac> kanzure: btw I had an interesting chat with Vinay on the tweeter the other night. i tweet little enough that you should be able to find it easily 12:23 < kanzure> vinay gupta? 12:24 < xentrac> natch 12:24 < kanzure> notch?? 12:24 < xentrac> naturally 12:24 < xentrac> it will probably infuriate you 12:24 < kanzure> most things tend to do that 12:24 < xentrac> yes, that's why I said that 12:24 < kanzure> i am mobile at the moment adn can't go searching. maybe later. 12:24 < xentrac> one of the disadvantages of amphetamine 12:24 < xentrac> Diablo-D3: well, that black hole is certainly computing a lot more than a measly few zetaflops 12:25 < kanzure> even if amphetamines do cause infuriation, i think it's wrong of you to assume it's the sole source of my infuriation. perhaps i am a naturally prone to finding exellent reasons to be absolutely unfuriated by mundane bullshit 12:25 < Diablo-D3> xentrac: but its not computing anything, its not a computer 12:25 < kanzure> *excellent 12:25 < kanzure> +? 12:26 < kanzure> *infuriated 12:26 < kanzure> mobile typing sucks 12:26 < kanzure> Diablo-D3: perhaps you should look into what computation happens to be :-) 12:27 < Diablo-D3> "A computation can be seen as a purely physical phenomenon occurring inside a closedÊphysical systemÊcalled aÊcomputer. Examples of such physical systems includeÊdigital computers,Êmechanical computers,Êquantum computers,ÊDNA computers,Êmolecular computers,Êanalog computersÊorÊwetware computers. This point of view is the one adopted by the branch of theoretical physics called theÊphysics of computation." 12:27 < Diablo-D3> How the hell did that paste like that. 12:27 * Diablo-D3 stares at both chrome and his irc client 12:27 < xentrac> kanzure: you are of course correct, and I didn't mean to imply it was the *sole* source of your infuriation 12:28 < kanzure> xentrac: what is the name of the physicist that i am thinking of? his name starts with an s and he has a wildly famous paper about computation and physics. 12:28 < kanzure> his name has an L in it somewhere 12:28 < xentrac> related to feynman, landauer, dyson? 12:28 < kanzure> oh probably, who isn't? 12:29 < xentrac> computation and physics is a very broad field 12:29 < kanzure> perhaps i should work on remembering authors other than by the initial letters of their names...... 12:31 < kanzure> hmm maybe this is more of an nsh paper than a xentrac paper, although i would be surprised if it turns out you have never seen this 12:31 < kanzure> he is somehow related to d'hoof't for some reason 12:31 < nsh> what are those space-invaders blockshapes for visual recognition of username/number hashes?
