It sounds like you're looking for problems in probability theory (rather than statistics). I don't have anything specific for you but you might have better luck searching for probl…

It has nothing to do with being easier to work with (at least, not in this day and age). The biggest reason is that minimizing sum of squares of residuals gives the maximum likelih…

We have no evidence that the lead in solder makes its way into the body of the person doing the soldering (and we've been at this for quite some time!). The concerns about lead in …

Really, do you think they've somehow fallen out of favor? If so, that's a surprise to me. In any case, they are a bit more advanced, and out of scope for the undergraduate course I…

As everyone in this thread is sharing links, I'm gonna pitch in, too. This lecture by Dennis Freeman from MIT 6.003 "Signals and Systems" gives an intuitive explanation of the conn…

I love the visualization! Thanks for sharing. How do you compute the fractional FT? My guess is by interpolating the DFT matrix (via matrix logarithm & exponential) -- is that righ…

That's pretty neat. I wonder how it works. It's not obvious to me at all how to build something like this, as the program doesn't know the sequence in which the player will reveal …

For those who don't recognize the name: Linus Åkesson (lft) is the one who made "Nine", that C64 demo with the wizard and nine sprites that was popular a few months ago ( https://n…

Apparently, this is a game that two can play. Niklaus Wirth, the creator of Pascal, had this to say in turn: "From the point of view of software engineering, the rapid spread of C …

This is by no means unique to programming. Many areas of knowledge are less accessible to those who don't speak English, and much more so to those who don't speak any of the dozen …

To nitpick with the grammar in the quote: It's capable of measuring to the accuracy of 120 μm at 1000 km. So it cannot accurately measure the diameter of a human hair (which ranges…

Not at all -- the usability and design are fantastic! (On desktop, at least.) What, specifially, do you find awful here?

If different components of the dataset have different units, I would argue that it is a prerequisite of clustering to first specify the relative importance of each particular unit …

Actually, scale-invariance only refers to scaling all dimensions by the same scalar (this is more clearly specificed in the paper linked by the article, page 3). For arbitrary scal…

> This tells me a lot about how a teacher thinks of students. This is quite an uncharitable perspective!

I wouldn't count on it -- LLMs make lots of errors in reasoning, and errors in solutions are very frustrating to most math students.

Not providing solutions is quite common in math textbooks, in part because professors (including the author!) want to be able to assign problems from the textbook to their class, a…

Check the "About" page. It's a self-published, non-peer-reviewed paper, written by a distinguished academic researcher.

Could you elaborate?

I agree that good definitions are important, but I don't know if this is a fair criticism (even if the sentence were wrong) -- the purpose of this page is to clarify a common point…
