egg|nomz|egg changed the topic of #kspacademia to: https://gist.github.com/pdn4kd/164b9b85435d87afbec0c3a7e69d3e6d | Dogs are cats. Spiders are cat interferometers. | Космизм сегодня! | Document well, for tomorrow you may get mauled by a ネコバス. | <UmbralRaptor> egg|nomz|egg: generally if your eyes are dewing over, that's not the weather. | <ferram4> I shall beat my problems to death with an engineer.
<egg|zzz|egg> bofh: today in genetic algorithm things: taking a power of the log of a probability
<UmbralRaptor> egg|zzz|egg: Are you *sure* that you aren't doing stat mech?
<bofh> UmbralRaptor: the two are honestly very closely related...
<B787_300> What would taking the power of the log of probability give you? Or rather why do you have your probability in log form and are trying to get it back to a normal form
<bofh> Yeah, now that you mention it I am slightly confused and think you want to do operations in a slightly different order here.
<UmbralRaptor> bofh: admittedly, ergodicity is probably indirectly relevant.
<B787_300> !define ergodicity
<bofh> B787_300: time average equals ensemble average
<UmbralRaptor> B787_300: a small chunk of a thermodynamic system ~equilibrium will go through every state of the whole system, given enough time. And time spent in a given state = amount of large system in that state.
<UmbralRaptor> (bofh's version is more concise)
<egg|zzz|egg> B787_300: bofh: I have my probability in log form because it would underflow otherwise, and the power is just because I need to steepen the fitness function so that the genetic algorithm converges
<egg|zzz|egg> (the exponential would be way too steep, underflowingly so even)
* UmbralRaptor wonders if people who modeled the system before included code.
<egg|zzz|egg> some of them
<B787_300> Underflow? As in be too small to accurately simukate
<egg|zzz|egg> underflow as in it's too smol for IEEE 754 binary64

<egg|zzz|egg> hm a noisy insect is being noisy
<egg|zzz|egg> whitequark: is котя still meowing?
<whitequark> egg|zzz|egg: hm no
<whitequark> she went outside and hasn't appeared for a day or two
<whitequark> (that happens sometimes)
<egg|zzz|egg> D:
<egg|zzz|egg> whitequark: are the kittens gone too?
<whitequark> no, the kittens don't go outside
<whitequark> we do plan to bring them out but they need to get vaccinated first
<egg|zzz|egg> whitequark: how котяlike is the котяchrome kitten
<whitequark> very
<whitequark> same color, very similar behavior
<whitequark> just calmer
<egg|zzz|egg> does she eat moths
<whitequark> hell yea
<whitequark> she eats *everything*
<whitequark> food, moths, fingers, toes, paper, metal, you name it
<whitequark> well, some things only tries to eat.
<whitequark> sometimes she very loudly licks the couch
<egg|zzz|egg> Ꙩ_ꙩ
<egg|zzz|egg> does she know how to open doors?
<whitequark> sometimes she eats the door.
<whitequark> but also yes
<whitequark> though she's not nearly strong enough for most
<egg|zzz|egg> she eats the door?!
<whitequark> gnaws on it yes
<whitequark> i think she has like, growing teeth or something
<whitequark> this only started recently
<egg|zzz|egg> moar stabby bits!

<kmath> <stephentyrone> @JamesWidman @slava_pestov He doesn’t really do window sills. He either takes half the bed or lies on the floor like the dog.
<egg|zzz|egg> whitequark: do you know where котя goes when she vanishes for days?
<whitequark> egg|zzz|egg: just wandering around
<whitequark> maybe visiting other people
<egg|zzz|egg> fun

<egg|zzz|egg> but it seems people tend to use it instead of 1D4C1
<egg|zzz|egg> stabbity
<whitequark> aw
<whitequark> wtf
<whitequark> where did that ℓ come from
<whitequark> I dind't type it for sure
<egg|zzz|egg> whitequark: no you didn't type it, I was just looking at the semilatus rectum article on wikipedia
<egg|zzz|egg> whitequark: and they use ℓ instead of 𝓁 which I think isn't appropriate (at least according to the Irish defect report)
<whitequark> egg|zzz|egg: oh
<whitequark> you typed it and now it's stuck in my terminal emulator
<egg|zzz|egg> oh lɒl
<egg|zzz|egg> whitequark: somehow I am good at breaking the systems of other people with UCS silliness
<egg|zzz|egg> whitequark: I permanently broke someone's IRC client at some point with the egyptian hieroglyph for star followed by the sumero-akkadian cuneiform sign for star
<egg|zzz|egg> (somehow other combinations of astral characters didn't do that, it was specifically this egypto-akkadian astral curse that broke their client)

<SilverFox> hey guys, yall know that saying "function over form", so what do you get when you do function / form?
<bofh> yes, the product will be silly, yes.
<egg|zzz|egg> bofh: yeah but then again the χ² is silly because I am terrible at optimization so

<SilverFox> have a meme
<bofh> SilverFox: ROFL
<SilverFox> another meme-ish, is dy/dx a fraction?
<SilverFox> it looks like one
<dx> beep
<SilverFox> sick, someone named dx
<bofh> dx: where'd you come from
<dx> yeah sure why not, a fraction of infinitesimally small deltas
<dx> bofh: i don't remember tbh
<dx> i saw this channel named somewhere and joined one day
<dx> like 6 months ago, apparently
<SilverFox> I really hate how fb makes their links stupid big

<iximeow> dx: hi
<dx> hiii

<SilverFox> g=10 gets me

<Qboid> (1,2): error CS0103: The name `e' does not exist in the current context

<Qboid> (1,2): error CS0103: The name `e' does not exist in the current context
<bofh> well other than the fact that there's no justification that f(x) is analytic
<bofh> !c M_E
<Qboid> (1,2): error CS0103: The name `M_E' does not exist in the current context
<SilverFox> it's porn math
<SilverFox> math written on boards during porn to make it seem mathy
<bofh> (if f(x) is analytic and that integral is taken over a compact subset of the radius of convergence of the power series then that integral/sum interchange is valid, mind you).
<bofh> ROFL THAT'S OUT OF PORN???
<SilverFox> yeah
<SilverFox> that's a porno
<SilverFox> that's why I said "Have some porn math"
<egg|zzz|egg> bofh: phl just noted that it works slightly better if the mutation rate goes down with time
<egg|zzz|egg> bofh: is our genetic algorithm going to have an annealing schedule,
<SnoopJeDi> bofh, remarkably accurate, considering the context!
<SnoopJeDi> guess somebody had a math text on hand
<bofh> egg|zzz|egg: I mean,

<bofh> 18:19:47 < SilverFox> g=10 gets me
<bofh> g=10 is close enough for some government work.
<SilverFox> disgusting
<SilverFox> what's g at top of mount everest?
<SilverFox> is it higher or lower than sea level g?
<SilverFox> at first thought I'd think higher, but idk
<bofh> Lower, consider G*m1*m2/r^2, m1 ~ 1, m2 the Earth's mass, and r the Earth radius vs the Earth radius + the height of Mt.Everest.
<UmbralRaptor> I'd be hesitant, given the non-spherical nature of earth. Got a gravity map on hand?

<egg|zzz|egg> bofh: re. the integral, tbh we don't have much context so perhaps they discuss whether f is sufficiently regular in the dialogue
<UmbralRaptor> egg|zzz|egg: pulling/pushing a cat is likely to annoy it, but a black square will be fine.

<bofh> egg|zzz|egg: touché.
<egg|zzz|egg> meanwhile I am bad at optimization
<egg|zzz|egg> bofh: what's the p value for χ² = 1511078 n = 282 >_>
<bofh> AAAAAAAAAAAAAAAAAAAA
<egg|zzz|egg> :-p
<egg|zzz|egg> bofh: okay but now I managed to get to χ² < 130 000
<egg|zzz|egg> bofh: which is still so stupidly high that I don't know how to compute the P-value, but it's an order of magnitude smaller! :-p
<bofh> knock it down another two orders of magnitude and then we'll talk :P
<egg|zzz|egg> bofh: but I don't know how to do that :-p
<UmbralRaptor> Something something χ²/ν.
<UmbralRaptor> But still…
<egg|zzz|egg> UmbralRaptor: 282 is smol
<egg|zzz|egg> bofh: yeah with an other order of magnitude throwing 2000 sig. dec. intermediate precision at it means I can compute the log of the P-value
<egg|zzz|egg> it's -5826
<egg|zzz|egg> bofh: and with two orders like you ask, 100 sig. dec. is enough! and you get log P = -298
<bofh> rofl
<egg|zzz|egg> bofh: which probably still means that you can confidently say that the system isn't the one you observe :-p
<egg|zzz|egg> bofh: argh my mutation rate cools too fast
