@rob Under a minute! Still a ways to go, though ;P

@ACuriousMind Mine was the third view of the question --- just happened to refresh the front page and see it at the top. Here I was the second view, but that one didn't need insta-deleting.

@ACuriousMind was that actually @rob? I see no trace of it

all I see is Deleted By Community

@EmilioPisanty The tally of who casts rude/abusive/spam flags is only visible to diamond moderators.

hah

@EmilioPisanty Spam/rude/offensive flags always show Community as the user.

@rob ah#

Now that there are awake people in here I'd like to ask again about this post.

so, what? you see a rude or abusive flag from rob, which is then binding and deletes the post?

@rob flagger's right that it's not a dupe, but I'm not a fan of the question at all

> calculations to be based on...

@EmilioPisanty My sentiments, precisely.

^ not a way to win sympathy, for sure

@EmilioPisanty Pretty much, yes

@ACuriousMind so, that makes the rude/abusive threshold?

seems excessive to me

@EmilioPisanty Moderator flags always have "infinite weight" and count as as much flags as are needed to clear any threshold :P

@ACuriousMind no, that's clear

@EmilioPisanty Gibberish can be flagged as rude/abusive, yes.

I just don't think it makes "rude" or "abusive" much

That is, the:

> kajuyhnhdjxhjxndnxkxkx. jiuy. "jhayjkee" nzxx xn"

is what qualifies as rude/abusive

¯\ _(ツ)_/¯

@EmilioPisanty If it were just a homework-like question, I would have just closed it. Mashing the keyboard to meet the character limit seems to me like an abuse of our system.

Flagged as offensive :P

Sorry, felines

Kets good, cats bad

not sure I agree, but let me depict in mathematical terms an estimate of the set of people who will mourn the passing of that question: $$\emptyset$$

My cat is in a superposition of good and bad.

anyways

I'm inordinately proud of that one. (link)

lol

as said by @dmckee,

I suspect the more sophisticated 'brain' response would be a plot of how responsive the brain is to various frequencies

@EmilioPisanty Although strange things happen to your pitch perception if you remove some interior harmonics.

plus, if I'm standing in front of an oncoming train I don't really care about the particular frequency of its siren; i care that it's coming right at me and I need to gtfo

@rob that just feels wonky

there's no way that sound is a human voice

@EmilioPisanty After I watched that video, I sat still for about twenty minutes and figured out how to make those sounds. It's exactly the right mix of "physics nerd" and "music nerd."

@rob in that case I suspect you'll enjoy this one

Although it's not a great habit to have. If you're distracted and start whistling to yourself, people ask what the tune you're making is. If you're distracted and start overtone singing, people sit up straight and say "WHAT IS THAT NOISE AND WHERE ARE THE ALIENS MAKING IT"

@rob heh

so... how do you actually sing overtones?

@EmilioPisanty Obligatory Goose

what I find interesting off the bat in there is that, while the fundamental is certainly at a lower amplitude when she's singing overtones, it's the least suppressed of them

so that makes me wonder what sort of a filter the mouth is applying in each case

(That one took me longer to find than I'd hoped :P)

One of Anna Hefele's videos has good instructions. It helped to have the software she uses to look at Fourier transforms while I sang.

Is she German?

After a while I figured out that my super-round-sounding "oooo" is pretty much limited to fundamental and first harmonic (octave), and that changing the vowel the tiniest bit makes the second harmonic (octave+fifth) pop in.

What seems to work best for me is to sing near the bottom of my range; then I have pretty good control over the major 7th series that lies up near the pitches where I whistle.

I was calculating this:

@rob yeah, no. that sounds creepy as hell.

any evil stares you get from doing that are well deserved =|

@EmilioPisanty Well, the next step from there is throat-singing.

::shudder:

@rob say what?

Which I never understood until after I'd watched some videos of people overtone-singing, and figured out what was happening. Then I found a performance of some throat singers and heard a clever little melody happening in the overtones.

@EmilioPisanty I was already pretty into this before he asked if people could play "logarhythms". A neat proposal.

part a and part b will give different values.

I was wondering part b

in part b, there are two distinguishable states: "orbital A is occupied, but orbital B is not." and "orbital B is occupied, but orbital A is not."

@EmilioPisanty Actually my original motivation for the overtone singing was that a chorus where I sing was performing this piece, which does some neat mixture between vowel mismatches (also an overtone phenomenon) and harmonies, but ends with some genuine overtone singing.

That recording isn't our group, but I did actually stand on the stage at the symphony hall and make those noises.

I was thinking (quite naively I think) if part b's result matches experiment, does that mean: the answer to my another question is "yes" (if putting indistinguishable particles into boxes making the indistinguishable particles distinguishable)

@0celo7 wald vs straumann?

for idc that much about gr but want to learn it relatively legit anyway

in other words, although "orbital A is occupied, but orbital B is not." and "orbital B is occupied, but orbital A is not." are distinguishable. Are the indistinguishable particles in the distinguishable orbital distinguishable ?

if the indistinguishable particles still indistinguishable, then we shall not have the result of part b. (in which we will have to assume two "states" are really distinguishable)

(okay, we count more than just two states in part b, but the relevent states to my wondering is the two states that "orbital A is occupied, but orbital B is not." and "orbital B is occupied, but orbital A is not." )

i hate my bad english and i can't edit what i have . said after a few mins...

correct: (in which we assumed two "states" are really distinguishable)

^ what's with this coming from a 2k+ user?

@EmilioPisanty reputation is an imperfect measure :P

(is my guess)

@DavidZ what?

I'm not bashing OP for not knowing some bit of physics

I'm puzzled that something that fragrantly off-topic comes from someone who's been here six years

@eulB Wald first but eventually both

Yeah, that's my point. Every once in a while someone manages to be here for six years and not realize that stuff like this is off topic.

heck, I'd even suggest account hijacking as a possibility

True, though that'd be a weird thing to do with a hijacked account

@DavidZ ¯\ _(ツ)_/¯

I'll check on that though. It is a possibility.

::blinks:: From Ben Crowell "And no, you cannot represent qubits as a lisp expression."

@DavidZ more like a younger sibling using the keyboard while the owner's away

I am suddenly stunned that it never occurred to me to ask that question (or anything equivalent to it)

Now that I seen that comment it seems like the most obvious question to ask.

@EmilioPisanty yeah, not much we can (or should, I think) do about that.

@DavidZ yeah, if that's the case then he'll see dmckee's ping

@rob were you just waiting for that close counter to hit 4?

@EmilioPisanty No, I was poking around to see whether I needed to add the comment that I added.

Oops, maybe we're talking about different questions now.

@rob dmkckee's link

@EmilioPisanty No, just slow.

@EmilioPisanty Hey, still wanna talk?

\o @Danu

@Danu I still want to pick your brains but I'm on the move

then float like a butterfly and sting like a bee :P

@EmilioPisanty Now isn't the greatest time for me either, actually

You can just try to ping me sometime during the coming days?

@BalarkaSen youtube.com/watch?v=vGgthQE8PkA secret early release from new album

@Danu sure

Hey @dmckee how did we miss actually checking the numbers? physics.stackexchange.com/questions/402177/…

@eulB OHHHH

Let's hear this

That plus the fact that the linked "explanation" actually solicits cash instead of providing a methodology... not pretty

Though the edited post does contain the kernel of an on-topic question

@BalarkaSen apparently that's the bonus track for pre orders so i guess it doesn't tell you how the actual rest of the album will be like

but lit

It doesn't actually click with me but I like it tho

it's not really clicky

it's pretty dispersed and hard to follow

true

i wonder whose style this is more like?

vs or the other dude?

I don't see that vehemently melodic Venetian Snare style

blame lanlan

but i still expect the album to have some really good songs in it

Same, I'm a big fan of some of Lanois-produced albums and finding Venetian Snares was like a gold mine for me

too much machine learning...head gonna explode D:

you're supposed to let the machine do the learning

indeed...

and it is currently doing that

at the same time, slowing down my laptop to a crawl

lol

@enumaris so anything new with ML these days?

lots

at least, I learned a lot with ML lol

reading a paper now that came out yesterday about Boltzmann Encoded Adversarial Machines

BEAM

but I've learned all sorts of neat algorithms recently...from something as basic as naive bayes and decision trees to more advanced stuff like Q-learning or genetic algorithms :D

fun beans

@enumaris so are you working on particular data or a problem? or mostly interested in learning different algorithms?

uh

yeah, I'm working on NLP lol

ah great choice. yeah lots of cutting edge stuff going on there and its worth serious $$$ too... are you working on a phd?

I've built a NLP pipeline for my company to do cleaning/pos/parsing/ner

most of the work is done by spacy...I just kinda tweak it

also I built a deep spell corrector that's a seq-to-seq model, but my computational power is too puny to train it effectively loool

@enumaris interesting spacy.io

yep, it's a good library

quite streamlined

your profile says your working on a physics phd?

my profile might be a year old

lol

I'll go update it...

so youre not working on phd or did you get one? fyi you might find this interesting... am gonna blog on ML in physics soon, its really buzzing/ popping lately...

I already got one

stackoverflow.com/users/8793975/enumaris?tab=profile

says "phd graduate"

@enumaris hey congrats on that! what was the topic? when did you finsih?

maybe it's phrased confusingly

my topic was neutrino flavor and spin transformations

finished last June

was that a US school? can you name it

UCSD

o.o

I guess u can find my thesis with that amount of information

lol

cool so what kind of company are you working at?

insurance company

I do the customer insights in the marketing department tho, nothing to do with the actual insurance part

@enumaris huh pretty innovative/ cutting edge if theyre doing speech rec (oh you said NLP)

well I'm not doing speech rec, just NLP

I do NLP on like written comments

yeah makes sense

tho, speech rec is on the table...heh

I could build them a deep speech recognizer...but Mozilla came out with one already open sourced

but the company doesn't like open source...

@enumaris o_O backward!

it's for security reasons

lol yeah have heard all the "excuses" myself over the yrs

yeah...

but I'm pretty busy (kinda) with my NLP piece anyways so they wouldn't have someone to maintain deep speech

any interest in AGI? check this out sometime for fun vzn1.wordpress.com/2018/01/04/…

what's AGI?

@enumaris "strong AI"/ artificial general intelligence

oh

that seems still far off

and I wouldn't be researching that at my company lol

@enumaris lol thats what everyone else thinks too :P

I don't think they pay me to research AGI...XD

@enumaris right yet its more valuable than anything, so consider it in your free time wink :P

I think for something like that, I would need a coordinated team of people to research with...

no matter how smart I think I am, probably AGI is out of my grasp :P

@enumaris you are not alone in those sentiments. but think myself AGI is on the horizon. think that others are overthinking it some... its possible all the "seeds" are now "lying around nearby"... o_O

I suppose with reinforcement learning, we can get closest to AGI...but the reinforcement learning algorithms would have bot be modified significantly

probably to include a lot of biases

@enumaris the essay sketches it out and is focused on RL somewhat. am doing a lot of related research (since then) & am going to write it up soon.

or...we could build a billion robots at once and have them all collectively learn maybe if you don't want to implement high bias...

@enumaris do not think "bias" is needed although that could be seen as related to my theory...

maybe....utilize a genetic algorithm to learn the biases, and then have a whole mesh of reinforcement learning algorithms on top...

that'd be like...legit DNA, but for robots

lol yeah something like that :P

well, if someone is willing to pay me enough, I wouldn't be averse to working on it

LOL

unfortunately deepmind never got back to me :P

@enumaris :( glad to hear you gave it a shot. dont give up, suggest trying again periodically

yeah I'm definitely not makin that kind of cash loool

me either whatever

lol so Physics is working for physics phds :P

I never post questions to physics lol

only to stack overflow

Have you tried MathOverflow?

I do see posts where the poster posted everything required of him, but because his problem was trivial, he was downvoted to hell tho

provided the source code, and full stack trace...but the problem was a typo so...-14 or something
