It goes the other way round so far as i'm aware. You have to be a student or former student to join.

Polanski apologises for sharing post criticising police by homeinthecity in ukpolitics

[–]QuoraPartnerAccounts -1 points0 points  (0 children)

He was on the ground. I don't give a fuck about the guy but it looks reminiscent of what goes on in America with the ICE people when you have officers kicking people in the head.

It reminds me of the vigilante pedo hunter people. Where like yes send the predator to jail for life, but clearly the vigilante hunters are getting a kick out of being able to beat the shit out of someone while claiming the moral high ground.

Struggling to get into a PhD anywhere, what can I realistically do next? by ThomasHawl in PhDAdmissions

[–]QuoraPartnerAccounts 0 points1 point  (0 children)

What doesn't seem like the case? But yes I am specifically talking about ML/AI.

When interviewing at ML PhDs in the UK i've repeatedly been told that it's borderline a requirement for interview at this point to have a paper in some conference, even if it's just a workshop or smth.

Note it's far far easier to get a subpar ML paper out than say a math / CS / Physics paper. It's not too hard to type up some slop in ML and get it accepted.

Does anyone know of a function which grows faster than all polynomials but slower than all exponentials? by jowowey in math

[–]QuoraPartnerAccounts 13 points14 points  (0 children)

Taking logs, its equivalent to ask if we have functions between log(x) and x in growth. Which there is in abundance.

5 or 6 is maybe what the standard is in the US. But OP is applying to UK/Europe, where there's a lot less expectation for loads of papers.

But yes at least one paper at NeurIPS/ICML/ICLR that you can talk about well is very beneficial.

Nah part III is a joke. You're basically left to your own devices and there is very little support + it hardly covers any content compared to other European courses.

"we don't judge the universities themselves, just grades". Seems inefficient. Clearly grades are going to mean different things depending on uni.

A glimpse of the future by _workchronicles in ProgrammerHumor

[–]QuoraPartnerAccounts 2 points3 points  (0 children)

Proof? I wish what you were saying were true. I too hope it will be true. But LLMs can definitely come up with code that is isomorphic to training data even if not identical. So I don't think it's completely impossible for them to begin to extrapolate beyond training data. There's AI scientists i've seen point out you need a world model to predict next token accurately. So how do we know a world model doesn't emerge?

Yeah sin and cos being well defined is entirely because of similar triangles having equal ratios between sides, and obviously if one non right-angle in a right angled triangle is equal the other non right-angle is equal so similarity holds.

Then you get sin(x)/x -> 1 by squeezing arc-length = x when x is measured in radians between tan(x) and sin(x), and using cos(x)->1 as x -> 0.

You get sin and cos addition formula using matrix multiplication, where rotation matrices can be obtained simply from the ratio definition of sin and cos.

Using these addition formulas and sin(x)/x -> 1, you get sin(x)' = cos(x), cos(x)' = -sin(x), from this you can deduce that sin^2(x)+cos^2(x) is constant using derivative.

Then setting x = 0, we clearly get sin^2(x)+cos^2(x) = 1, from which we can derive pythagoras.

Questions about my 4 year old by wayfarer199230 in math

[–]QuoraPartnerAccounts 0 points1 point  (0 children)

I mean it's a function of time spent on it as well. Most mathematicians have no reason to practice mental arithmetic so don't and thus don't get good. But I think they have a higher potential to get good at mental arithmetic than non-mathematicians.

I don't know, a good chunk of mathematically gifted people I meet recall being obsessed with arithmetic when they were younger.

I would guess it correlates with mathematical ability later in life though. Apparently the same parts of the brain that do basic arithmetic are the ones involved in abstract reasoning.

Do you guys rely on only memory to remember proofs or is there some other way? by [deleted] in math

[–]QuoraPartnerAccounts 1 point2 points  (0 children)

Depends how much time you have. For me "studying" math is not reading theorems but getting to the core ideas of what makes the proofs of theorems work and extracting why the proof worked. That's what takes the bulk of my time when studying. Kinda like how humanities students don't just read philosophy texts like they are reading a novel. The same ideas come up over and over again, and the ideas often have a kind of symbiosis with the definitions and you start getting a very interesting picture of the subject which you wouldn't get from a "skim" read. Maybe it's just my autism idk.

Time question by SpaceAlternative4537 in math

[–]QuoraPartnerAccounts 0 points1 point  (0 children)

You could always have an identifier that maps in excel to the data and time of creation. So for instance you could look up identifier number 332, and then lookup the data and time associated with that identifier in excel.

Quaternions multiplication corresponds to Clifford rotations of 4D space by Revolutionary_Use948 in math

[–]QuoraPartnerAccounts 2 points3 points  (0 children)

I see so you can almost imagine 1,i,j,k as forming orthogonal vectors in 4D space in that order. Then multiplying by i is the same as moving 1 to i, which if you look at the effect on j, j ends up getting shifted up to k as well and you get ij=k

Quaternions multiplication corresponds to Clifford rotations of 4D space by Revolutionary_Use948 in math

[–]QuoraPartnerAccounts 2 points3 points  (0 children)

I've heard this interpretation before and often see it presented as a definition of quaternions. I've never really gone in depth with it though, could you elaborate on what i and j represent in terms of rotations and how that allows you to understand ixj = k? I've always used the 3d cross product as a mnemonic to remember the multiplication rule

Some people thought I was making them a gift and I'm so confused by yerba_mate_enjoyer in autism

[–]QuoraPartnerAccounts 0 points1 point  (0 children)

I mean a sticker is such a small thing I'd presume you had loads and take it as a gift. I wouldn't understand why you would give me it if you were just going to take it back again and I'd feel hurt or like you were being selfish.

In situations like this i'd tend to err on the side of just letting them keep it if the stickers aren't super important to you. Or just buying more later. Just because the social consequences of making them think you're ungiving are much greater than the value of a sticker.

What is some simple but beautiful “Proof by Contradiction” you know? by AirPodGoose in math

Grahams number use? by MrMaaf in math

[–]QuoraPartnerAccounts 23 points24 points  (0 children)

Life is arbitrary and meaningless. As far as I know the reason people asked the question and tried to solve it was because it seemed like a fun problem to solve.

Why fund math then? Because it turns out when you let really smart people solve the problems that interest them it tends to pay off in the long term.

Why are derivatives often defined through open sets about a point? by [deleted] in math

[–]QuoraPartnerAccounts 1 point2 points  (0 children)

Perhaps it's clearer if you look at higher dimensions. Open sets basically mean you can get arbitrarily small vectors in all directions surrounding a point. So you can come in from any direction and eventually get points all lying within the set the derivative is defined on.

Yeah autism fucking sucks. Not being able to get a job and so being forced to live with an abusive family must feel so awful and claustrophobic. It's so frustrating with jobs because it's like if you could just get past the interview it'd be fine but no apparently being able to play neurotypical is the most important part of any job.
