    The production of tears is left as an exercise to the reader. /s Thanks for reading. The 2D simulation section might be more interesting on a first read — it makes the math less my…

    Hey, I’m the post author — thanks for reading. Theta represents all the model params — all the weights in the neural network. The convention is to write theta for the “learned” sco…

    Interestingly, they’re actually used all the time in LBO models. Because the default is to sweep all FCF to pay down debt, but then the interest expense is dependent on FCF, which …

    If you're interested in this, check out Cover's Information Theory textbook — the rabbit hole goes much deeper. One of the most interesting examples, is that when you're betting on…

    Won't you possibly get some information about some passengers by doing this, if you know / can figure out the distribution of the random numbers? E.g., say that the random numbers …

    FWIW, I think the best "applications" (if they can be called that) come from domains like algebraic topology and algebraic geometry, where some concepts come up so frequently that …

    Although, to play devil's advocate, you can prove results with set theory that you'd care about even if you weren't super interested in foundations, usually by playing with differe…

    I mean... the parent post is right, the site I linked seems to be calculating CA state tax incorrectly. But: 42% is the effective tax rate (not marginal, average). And this is pret…
