jrayhawk | kanzure: re: ikiwiki access: no; you could probably fake it imperfectly enough to throw indexing bots off your trail with some apache directives on the relevant paths. | 00:57 |

jrayhawk | But cgit and ikiwiki.cgi can probably be made to expose stuff with by using POST to feed it variables. | 00:59 |

maaku | xentrac justanotheruser: everything that is wrong with AIXI | 07:09 |
maaku | AIXI is basically "exhaustive/brute-force search for a solution". AIXItl is "make it technically computable by cutting off the brute-force search at some limit" | 07:10 |
-!- atomical [~atomical@wl2142.cin.net] has quit [Ping timeout: 264 seconds] | 07:10 | |
maaku | AIXI is of approximately zero interest to making an AGI because it is incomputable | 07:11 |
maaku | AIXI-tl makes itself computable simply by setting a watchdog timer and terminating ... not interesting | 07:12 |
maaku | it does nothing of interest to actually make sure that what is computed in the time available is of any relevance, and therefore would be hideously inefficient | 07:12 |
maaku | and, no surprise, it's a publishable achievement when AIXI-tl is able to be used to solve even the simplest real world problems | 07:13 |
maaku | xentrac: what are you trying to do that would have you look at AIXI? | 07:14 |
poppingtonic | Even more inefficient would be doing inference on mcmc or particle cascade approximations of AIXItl's output. | 07:15 |
poppingtonic | Also, AIXItl can't model itself as a part of the environment. | 07:16 |

justanotheruser | maaku: I heard a rumor you're working on your own AGI system? | 10:54 |
-!- c0rw1n is now known as c0rw|away | 11:02 | |
maaku | justanotheruser: yes | 11:02 |
maaku | for some definition of "working" | 11:02 |
xentrac | maaku: basically pasky's take | 11:03 |
maaku | justanotheruser: bitcoin/blockstream tends to take priority ... but that's really just to provide leverage to feed forward into an AGI-centered transhumanist project | 11:04 |
-!- drethelin [~drethelin@24-241-226-112.dhcp.mdsn.wi.charter.com] has joined ##hplusroadmap | 11:04 | |
justanotheruser | Is this the point where I suggest you make blockchain based AI? | 11:04 |
* maaku shoots justanotheruser | 11:04 | |
justanotheruser | lollll | 11:04 |
justanotheruser | Is there a public repo, or papers, or is the project still in its infancy | 11:05 |
maaku | in all seriousness people worried about AGI x-risk should be working on bitcoin now. we are -today- working on verifiable computing technology in adversarial environments while there is nothing but money on the line | 11:06 |
justanotheruser | Yes, it would suck for an edge case to kill all humans | 11:07 |
xentrac | maaku: that's a very good point | 11:08 |
xentrac | maaku: how do you feel about the hardware and OS security landscape? | 11:08 |
maaku | justanotheruser: Much better for an edge case to just result in theft and litigation! | 11:08 |
xentrac | I finally installed a Ⓑ client | 11:08 |
xentrac | well. I'm still 30 weeks behind on the blockchain | 11:09 |
maaku | justanotheruser: also by happenstance the generalized script2.0 tech that people like gmaxwell and myself are interested in (it's my current research focus at blockstream) happens to overlap very nicely with the requirements for a base VM language in my AGI design | 11:11 |

maaku | xentrac: one of the things I'm involved with is open hardware and fully verified platforms | 11:12 |
xentrac | so what's the state of the world? | 11:12 |
xentrac | my impression is "we are up shit creek" but maybe there are things I'm not seeing | 11:13 |
-!- Quashie_ [~boingredd@ool-18bccfe5.dyn.optonline.net] has joined ##hplusroadmap | 11:13 | |
xentrac | not, any more, because we don't have the formal methods, but because we don't have access to manufacturing facilities | 11:14 |
kanzure | if you are okay with large feature sizes then manufacturing is slightly more doable as a homebrew project | 11:15 |

xentrac | maaku: what does the possible paper path from verified Chisel to physical silicon look like? | 11:23 |
maaku | Complicated :) | 11:23 |
xentrac | does that mean "infeasible to make verifiable"? | 11:24 |
-!- erasmus [~erasmus@unaffiliated/erasmus] has joined ##hplusroadmap | 11:24 | |
pasky | I'd expect it to be more fruitful for now to focus on making the thing actually generally intelligent in some rudimentary sense rather than work on vm languages etc. | 11:24 |
maaku | Oh I agree I'm not an x-risker | 11:25 |
maaku | But such VM languages is my day job and I've long since learned the value of double dipping work | 11:26 |
xentrac | :D | 11:27 |
Diablo-D3 | ssh client bug: http://undeadly.org/cgi?action=article&sid=20160114142733 | 11:30 |
maaku | Such a VM is needed for my agi design regardless of x-risk | 11:34 |
maaku | It is a good target for evolutionary search over program space guided by reasoning | 11:36 |
xentrac | a verifiable-computing VM, maaku? | 11:37 |
xentrac | Or what kind of a VM? | 11:37 |
kanzure | a verified virtual machine that runs other verified software | 11:40 |
-!- juul [~juul@juul.io] has quit [Quit: WeeChat 0.4.2] | 11:41 | |
xentrac | well, so these are two different approaches | 11:41 |
kanzure | unfortunately i would have to say i am an x-risker, i'm just the other side of it (the one that everyone else seems to be worried about) | 11:41 |
xentrac | Bitcoin Script runs on a *verifiable* VM, in the sense that the computation gets replicated on other nodes, and they stochastically vote on whether to accept the results of the computation | 11:42 |
nmz787_i | xentrac: open hardware is only closed if you're not on the inside | 11:42 |
xentrac | in theory you could have multiple independent implementations of that VM so that a bug in one of the VMs would be caught by the others when they tried to replicate the computation | 11:42 |
xentrac | although AFAIK nobody does | 11:42 |
nmz787_i | I mean non-open | 11:43 |
xentrac | but that's different from a *verified* VM where you've formally proven that the implementation fulfills its specification | 11:43 |
xentrac | nmz787_i: ah, that makes much more sense :) | 11:43 |
xentrac | I don't think it's actually true though because nobody is on all the insides | 11:43 |
nmz787_i | I work at Intel | 11:44 |
xentrac | You probably know a lot of things I don't, so I could be wrong | 11:44 |
nmz787_i | but yeah, super big company, would take whole career to even get a decent overview as well as insight to innovate on ALL the processes | 11:44 |
kanzure | why would you need to innovate on everything? | 11:45 |
nmz787_i | hplus yo | 11:45 |
maaku | Hah! I'm with kanzure. Destroy humanity! (and maybe replace it with something better) | 11:45 |
nmz787_i | just name that AI humanity, and its still hplus | 11:46 |
-!- juul [~juul@juul.io] has joined ##hplusroadmap | 11:46 | |
maaku | Anyhow, my AGI design involves de novo concept learning using evolutionary search, guided by its knowledgebase. | 11:47 |
nmz787_i | .wik silicaphobic | 11:47 |
yoleaux | nmz787_i: Sorry, I couldn't find article. | 11:47 |
maaku | "Guided by its knowledgebase" means probabalistic reasoning providing heuristics to guide search | 11:47 |
maaku | "Verified software" means proving properties about code, which is a specific application of program reasoning. A VM designed to be easy to prove properties about is generally easy to reason about the behavior of programs, which makes it an easy base language for evolutionary search | 11:48 |
kanzure | the other day you mentioned that you find humans too superstitious. but even with high levels of superstition, they seem to still do interesting computations that we have not yet figured out how to make computers do. doesn't this support the idea of reverse engineering some more? | 11:48 |
kanzure | also, grounding problem stuff goes here | 11:48 |
maaku | kanzure: This may be my own ignorance, but I sincerely don't know any neocortical algorithms that we can't do better or have ideas for doing better on a computer | 11:50 |
kanzure | what is a neocortical algorithm? | 11:50 |
maaku | I am interested in the old brain and expect to learn quite a bit from studies of that, including how our emotions work fundamentally | 11:50 |
maaku | *emotions and drives | 11:50 |
maaku | kanzure: things done by the neocortex | 11:50 |
kanzure | neocortex has not been enough, so far, based on previous fidelity/resolution of simulations | 11:51 |
maaku | kanzure: as you know my goal is to build an 'artificial scientist' / 'artificial engineer' . to THAT end I do not expect anything interesting to come out of brain science | 11:52 |
kanzure | what level of evidence would be required to convince you that the brain reverse engineering strategy is better? | 11:54 |
maaku | evidence that human beings are actually good at doing science :\ | 11:55 |
kanzure | so far we are better than known computational implementations | 11:55 |
kanzure | so..... | 11:55 |
cluckj | we're the only ones doing it afaik | 11:55 |
kanzure | indeed. | 11:55 |
kanzure | well there's some partial implementations | 11:55 |
kanzure | some weird stuff. like robot labs. but they have extremely limited scopes. | 11:55 |
maaku | kanzure: not really. human beings augmented with non-human components do science -- we have methods and procedures external to ourselves that force good outcomes and censor bad behavior | 11:56 |
kanzure | we do it better than a dog, and better than a markov bot. | 11:56 |
maaku | i think we are talking past each other | 11:57 |
cluckj | the machines we do science with don't have the same kind of agency that humans do | 11:57 |
maaku | i just mean simple things like scientific rigor | 11:57 |
kanzure | maaku: i think standards for convicing evidence is completely fair game. | 11:57 |
cluckj | and we kinda....make those machines | 11:57 |
maaku | that's not something that comes naturally to humans and is something we struggle hard with | 11:57 |
maaku | cluckj: so we're fully general. that doesn't mean we're *good* at it | 11:57 |
cluckj | I feel like "good" needs a point of comparison | 11:58 |

maaku | cluckj: i can build a machine learning program to identify people by gait or voice. doesn't mean I'm good at it | 12:00 |
kanzure | yes, so i think "evidence that humans are OK at it" is not a good response. | 12:00 |
kanzure | identification is a falsehood- any data can mislead a program into identifying people by gait.... | 12:00 |

pasky | maaku: I've been doing genetic programming and evolution a bit on and off and my lesson learned is that there's vast prior art and a lot to learn and *still* it's not useful for really high-dimensional problems and very tricky to get to work otherwise | 12:51 |
pasky | so I hope you have some pretty clever ideas about how to make your evolutionary search work | 12:51 |

pasky | while that pdf is loading, what do you mean by "in general"? | 13:13 |
maaku | xentrac: the need to verify the safety (software properties) of a contract before signing | 13:13 |
maaku | e.g. can this script steal my money | 13:13 |
maaku | pasky: nothing complex, just MOSES | 13:14 |
maaku | pasky: the key is to not have an achitecture that relies on one mechanism for everything ;) | 13:14 |
maaku | evolutionary program learning works for limited tasks. use other stuff for other tasks | 13:14 |
pasky | so exactly what nontrivial tasks does evolutionary program learning work on? | 13:16 |
pasky | xentrac: (for functions that aren't too highdimensional nor too lowdimensional, say 100-1000D, and have a very rugged landscape, methods based on genetic algorithms like BIPOP-CMA-ES are state-of-art; I think that's the most positive statement one can make about GA applicability) | 13:18 |

kanzure | http://diyhpl.us/wiki/transcripts/gmaxwell-bitcoin-selection-cryptography/ | 15:00 |
kanzure | " There was this rallying call, "information wants to be free". And I knew in my bones that this was true. We were going to use computers, which turn everything into information, and we would use networks to hook all of the computers together and we would change the world. We were going to change the power balances, make more people more empowered and everyone would have access to the world's knowledge and they would all fulfill their ... | 15:00 |
kanzure | ... potential. That's a very political take on something that I now think in fact is better described as a law of nature. This is not just that I want information to be free; no, information really does want to be free. It is fundamental that information will percolate out into every little nook and cranny, and you can't control it. The result is that often bad things happen because information wants to be free. Sunlight is the ultimate ... | 15:00 |
kanzure | ... solvent, but solvents corrode. So my email wants to be read by the NSA. When I try to login to my server, it can't tell me from you, because you can just replay my login. And now you're logged in as me. When you go and browse the internet, people learns how it works. They see inside your mind what used to be completely private. When I go to research something, marketers can send out cheap spam, and that spam is just as visible as the ... | 15:00 |
kanzure | ... information I seek. If I want to build a digital cash system, I can't, because information is perfectly copyable. And all copies are just as good. Money that you can just copy is not much of a money at all. So you have an environment where there are powerful parties that have more ability to use this fundamental nature of information, and this goal of everyone being more empowered may not come true." | 15:00 |
kanzure | btw, gmaxwell does not claim to be a cryptographer, in fact i think he always tends to drag a disclaimer nearby. | 15:01 |
kanzure | oops maybe not. i don't have a quote from him on this. | 15:01 |
fenn | * actually an ubercryptographer | 15:02 |
