    Isn’t the point more “it’s easy to fall into the trap to believe that predicting when the sigmoid is going to bend is possible and the right heuristic is to instead extrapolate loc…

    Yes it does sound like his approach is quite smart and altruistic, but it’s a shame that that aspect just isn’t covered in more detail.

    It is great that he’s doing this and it’s making the world a better place. It’s a bit disappointing that in articles like this there’s relatively little discussion around what orga…

    I think what would be great is to have eg a concise example where it works well for you and a concise example where it doesn’t. This shows you have explored it and thought about it…

    By this logic a lot of applied maths papers become “does not compile” :D

    Yes in theory, but not yet in practice because not everything is fully formalised.

    Yeah 3 - 4 is typical in STEM at Imperial, depends on the scholarship or funding source. The standard funding tends to assume 3 - 3.5 years, but I vaguely recall that in some depar…

    I was in a similar situation as the parent post and skipped/was moved up by two years of high school. I think it was very beneficial to have to work hard to catch up with more adva…

    There’s also a vague argument around hedging some actual risks that some market participants genuinely want to hedge… which depends a lot on the specific bet. Eg hedging exposure t…

    By “not terrible” you mean “bad but not very bad” and not “good” right?

    It's possible but unlikely given the short timeline, diverse questions that require multiple matheamticians, and low stakes. Also they've already run preliminary tests.

    Interesting topic and seems like a reasonable thing to study. It would be cool to see a study where participants behave in a way that leads to more light exposure in month A and th…

    Yeah sure SU(2) up to sign is isomorphic to SO(3) and whatnot… I think it’s probably mostly the computer graphics history and the cool name that gets people excited about quaternio…

    I like quaternions as much as the next guy (I’ve used them in numerical computations etc), but what is it about them that makes them show up on the front page every few weeks?

    As a practitioner in this area, I’d say some of the authors here stand out as extremely influential to this day. Clearly these include: Cliff Asness (AQR is huge, lots of publicati…

    Imo the fun quant stuff these days is about predicting returns and not pricing derivatives. As others have said here, the pricing part is mostly commoditised and more about managin…

    Yes the combination of Krylov and quasi-Newton methods are very successful for physics problems ( https://en.wikipedia.org/wiki/Quasi-Newton_method ). Iirc eg GMRES is a popular Kr…

    Yes. Some scientific computing code is still being developed in Fortran eg in HPC. (and has been for decades)

    Yeah and this is a much more intuitive way of generalising from the n = 2 case. Weights are proportional to inverse variance even for n > 2. Importantly this assumes independence s…
