especially with IDs, to a European citizen it sounds utterly crazy that you guys use your driver's licenses as your primary indentifying documents
<APlayer>
Wait, and what happens if someone has no driver's license?
<hattivat>
better, what happens if someone loses their driving license because of speeding or drunk driving?
<hattivat>
I don't know the answer, but I assume they give you some special certificate instead?
<whitequark>
APlayer: everyone gets their driver's license before age of majority
<whitequark>
because it's not really a country accessible without a car
<hattivat>
in any case, the idea of using something that you have to pass an exam and be physically able to obtain, and which you can be stripped of for misconduct as the default way of identifying people is utterly bizarre to me
<e_14159>
hattivat: s/idea of using something that you have to pass an exam and be physically able to obtain, and which you can be stripped of for misconduct as the default way of identifying people/US
<Qboid>
e_14159 thinks hattivat meant to say: in any case, the US is utterly bizarre to me
<APlayer>
whitequark: Uh, this is law. They can't count on people obtaining their driver's license for something as vital as a personal ID
<hattivat>
e_14159: that is true as well
<hattivat>
whitequark: ok, but what if you are disabled and unable to drive?
<hattivat>
and what if you lose the document for speeding
<hattivat>
or do you guys not have this penalty?
<APlayer>
"There are no such people" :P
<hattivat>
maybe that's the reason so many American corporations are so keen to research self-driving cars
<whitequark>
APlayer: driver's license is not the only way of proving your identity, of course
<whitequark>
there's birth certificates and concealed carry permits
<hattivat>
so that diabled people can finally have proper documents ;p
<whitequark>
ironically if you don't/can't have a driver's license then a concealed carry permit is the next easiest thing to get
<e_14159>
o_O
<egg|zzz|egg>
Ꙩ_ꙩ
<Iskierka>
matlab people are dumb
<hattivat>
wait, you can use a concealed carry permit to prove your identity, like at a bank? xDDDDDD
<UmbralRaptor>
You can get a state ID from the same places as driver's licenses.

"This person is not eligible to obtain a driver's license because of drug abuse. Let's allow them to carry hidden weapons instead! Yay!"

<Iskierka>
it's not like it has a photo that would be useful
<hattivat>
well, that's the same all over the world, I think, with credit checks
<hattivat>
but presumably you first need to prove that you are who you say you are
<whitequark>
no, the US form is especially insane, as usual
<Iskierka>
I also fail to understand the logic behind concealed carry at all
<hattivat>
and a concealed carry permit is a rather weird way to do it to my taste
<egg|zzz|egg>
Iskierka: tbh french driver's licenses don't need to be renewed, so the photo is useless :D
<whitequark>
you have to get credit and repay it in time for many years to get a good credit score
<UmbralRaptor>
APlayer: that's less silly when you realize how harsh MJ penalties are in some places.
<Iskierka>
like, why would you WANT it to be legal for people to hide weapons, so if you can see signs of a hidden weapon, that's not cause for suspicion?
<whitequark>
so if you didn't need/used credit at all a mortgage would be super costly for you
<Iskierka>
if carry is legal, open carry only, thanks
<Iskierka>
anyone hiding it gets taken down
<UmbralRaptor>
Iskierka: people who read suicide / homicide / mass shooting numbers in the wrong order?
<Iskierka>
but how does "but mass shootings" justify concealed carry over open?
<Iskierka>
if you're happy to carry, why do you want it secret?
<UmbralRaptor>
¯\_(ツ)_/¯
<APlayer>
The US just sank down further on my "sanity list".
<Iskierka>
it does but I don't understand why concealed carry should be allowed at all
<Iskierka>
you only have reason to hide a weapon that you intend do to something shifty with
hattivat is now known as hattivat|afk
<Iskierka>
so make it so any hidden weapon is illegal for being hidden, as well as whatever they intended it for, so you don't have to make judgement calls each time you think someone MIGHT be hiding a weapon
<Iskierka>
if it's hidden, it's illegal. No carry licenses
<APlayer>
"Licenses are rarely issued to ordinary citizens. However, no permit is required to openly carry a rifle or shotgun."
<Iskierka>
that part's an entirely separate bit of stupidity
<whitequark>
it's not
<whitequark>
have you seen how huge and how rural US is
<whitequark>
having a weapon on you when you live in the middle of nowhere on a farm is pretty much a necessity
<Iskierka>
so is a vehicle, yet that still requires full licensing
<UmbralRaptor>
Kinda. Population is mostly urban.
<Iskierka>
and these justifications for rural rules still apply in the urban areas of the same jurisdiction
<Iskierka>
s/still apply/are still applied/
<whitequark>
UmbralRaptor: but the constitution was specifically written so that urban and rural populations would get roughly the same voting power
<Qboid>
Iskierka meant to say: and these justifications for rural rules are still applied in the urban areas of the same jurisdiction

Fiora: https://twitter.com/FioraAeterna/status/919315793283661824 << so this is a french thing, which afaik dates back from wartime, when butter was scarce; people made croissants with margarine, and distinguished the butter ones by making them straight (rather than crescent-shaped)
<kmath>
<FioraAeterna> @merrittk i googled "straight croissant" and found this https://t.co/x5rqfFpLRD
<egg|zzz|egg>
Fiora: the straight shape stayed

that is a weird way to distinguish the two, IMO. means you have to bake two separate pastry styles.

this machine learning coursework asks you to take a random selection of the full dataset for training samples. Problem: how do you test accuracy when it's trained differently each time
<hattivat>
by ensuring sufficient randomness and a sufficiently large dataset

<Qboid>
hattivat meant to say: also, the standard technique is to use the whole dataset, using ~2/3rds for training, and 1/3rd reserved for testing
<Iskierka>
I've gotten between 0.99202 and 0.98004 on the same (low-accuracy) training run
<hattivat>
0.992 accuracy on test data?
<e_14159>
Rather, split it into training (to train the algorithm on), validation (to optimize hyperparameters on), and test (to evaluate final accuracy) set
<hattivat>
that's assuming he needs a validation step, depends on the technique used and the workflow he has
<e_14159>
True. But it's something I see often (and unfortunately do myself...)
<Iskierka>
we have 200/500 for training, but expected to take a random set. I can see how to solve this for a consistent set, but a later question implies you are meant to see per-run deviation ... after you've already compared training accuracies for increasing k, when k=1 is already on average above the variance for higher k
<Iskierka>
and this is just k-nearest-neighbour as it's early coursework, so I don't think validation is relevant
<Iskierka>
I've seen 0.99 on some runs with k=1 and 0.98 for some runs with k=4. How am I supposed to conclude increasing accuracy
<e_14159>
You're not, I think. A larger k does not relate in any way to more accuracy.
<SnoopJeDi>
My (very limited) understanding is that how to split training/validation in a Good Way is one of the most challenging problems in ML

… why did I get an advertisement for an honor society visa card?

I have the problem that most soft drinks taste far too sugary for me even when not flat (and are undrinkable when they lose carbonation). But cherry zero ain't bad flavour-wise, I'll agree there.
<whitequark>
so I tried to quit drinking coke recently and I've realized something
<whitequark>
apparently, my brain now relies on either (a) sugar in it or (b) caffeine in it, and refuses to work unless served
<whitequark>
I *think* it's (a)

because sugar-free drinks, even when they tasted right, didn't quite did what I expected of them
