    Gd dominates ridge regression but not sgd! Surprising that such simple things aren't known for linear regression

    Such bs. The majority of math majors or even math phds and faculty could not win a gold in imo.

    Replying to @GaryMarcus
    What most people don't realize is that IMO (and IOI, though to a different extent) aren't particularly hard. They're aimed at high schoolers, so anyone with decent uni education should be able to solve most of them.

    See below on what Zuckerberg is looking for in star recruits worth $100m pay packages for Meta’s plans in Artificial Intelligence. But weren’t some people saying calculus is no longer useful in the AI age? 🤔
