    ChatGPT runs moderation filters on top of your conversation and will highlight responses or prompts red if it thinks you're breaking TOS. The highlight is accompanied by some text …

    I know that revealing the features they use to spot AI submissions would just make their job harder, but I can't help but be curious what sort of features they are looking for. I f…

    Agreed. Presenting this feature solely as a tool for users with cognitive disabilities might undersell its potential. There's a significant number of smartphone users who only util…

    For me the magic of BOTW was the way its design encouraged you to approach the game more as an environment for free form play. My best experiences with BOTW were when I turned the …

    I also tried this out and the balloon example as well. User: Barbara, Mary, and Harry had red balloons. Ted had a blue balloon. Sam also had a red balloon. How many children have r…

    My take on btilly's problem was that the difference between the convergence rates is not constant but rather known to be bounded away from zero by some unknown constant. That is, t…

    Yes, I realized after posting that this is probably a better paper to link to: http://cseweb.ucsd.edu/~yfreund/papers/bandits.pdf The algorithms for the partial information setting…

    I think what you're describing is basically the non-stochastic setting. The idea there is to assume absolutely nothing about the rewards (they can be generated by quickly changing …

    His numbers may be high but $40-50k/yr is pretty low. My impression is that software developer positions at top companies (Google, Microsoft, Facebook, etc) pay about 2x that.

    I think the problem is more complicated than basic supply and demand. There is a lot of demand for college education. Enrollment is higher than it has ever been, and the people pro…

    It's true you need to compute the kernel dot product between every example you see and every example in the support set (every example that ever previously evaluated to signed marg…

    The set of support vectors is just the set of training examples that have non-zero alpha parameters. To implement the gradient update you just evaluate the support vector machine o…

    I think what VBprogrammer meant is that thinking you've found a bug in a compiler / OS / CPU is often a warning sign you're a poor programmer. Often times a beginner will have a bu…

    It sounds like he's saying it's hard for Julia to interop with languages that don't support arrays of inline structs (e.g. Java). I could be misreading it though.

    Having a very small (even one pixel) hit box for the player is actually sort of a tradition for this kind of game: http://www.significant-bits.com/the-1-pixel-collision-box Having …

    The problem is that standard statistical tests have two outcomes: (1) "reject the null hypothesis" or (2) "failure to reject the null hypothesis". Moreover in the most common stati…

    It's impossible to know whether or not Linux would exist without GNU, but GCC isn't something you can hack together in a few months. Clang is the closest thing to a GCC replacement…
