There are algorithms to add variables and observations to an estimated linear regression model, so scaling is not an advantage of gradient descent. You should mention in the post that there are better ways to estimate this model, even if yo

I love this analogy. But, to continue it a little further, the article and discussion are about "preventing meat from rotting during transportation," and you seem to be saying, "screw it, the customer should know not to buy t

Companies already can choose to interview anyone who's taken relevant coursework, but usually can't commit that much time so they screen applicants first. If the grades in a few particular online courses become widely known for ge

It would be fun if the general solution was making online classes absurdly hard . Unfortunately, it's hard enough to stop cheating on exams in physical lecture halls, so once a high grade guarantees students job interviews....

Two thoughts: 1) this is a somewhat bizarre exercise. It seems like it's more relevant to work out the probability that the better team wins, for empirically relevant values of what the author's calling "expectation value&quo

It somehow hits me as cutesy and "not serious." (can't think of a more specific way of putting that, sorry.) Nothing wrong with that if that's where you're going, but isn't what I'd think of as "opini

I've used TeX with eplain and for many purposes it's great, but publishers and coauthors essentially mandate LaTeX for real papers. Pollen is intriguing[1,2], but way too early to say anything about. If TeX or LaTeX are going to b

Definitely; pandoc is great and most people are better off using it than LaTeX directly. The comments above mine meant "replace" as in "displace," though and some of the important functionality of LaTeX, stuff that matte

It gets better... Well, LaTeX doesn't, but you'll eventually converge on a set of packages and workarounds that fit your writing. Macros are local to the environment where they're created, so you can get around a lot of cut a

If you haven't dealt with catastrophic package conflicts, I have to wonder how involved the projects you're writing are.... and I'm somewhat surprised by the claim, "...equations... just work." They "work,&quot

I didn't downvote you, but vague comments idly questioning the point of the article usually don't do well on HN.

Finally, a role for the DFW-inspired footnote-heavy writing style! Edit: to be more constructive, it doesn't seem like this would be hard to represent in the underlying data: ... <p>omnia haec, quaecumque feret uoluntas

Just to add to your first point: it's hard for people to recognize that there can be a huge difference in ability between the best and the 20th best team. They can both be great, but the 20th best team is much less great than the bes

I don't know what OP meant, but I've found booktabs to be essential for making attractive tables. The package manual is pretty informative: http://www.ctan.org/tex-archive/macros/latex/contrib/b

That paper is a very different setup --- the hierarchical model Gelman, Hill, and Yajima use implicitly builds multiple comparisons into their process. You could do the same thing here in principle by drawing alpha and beta for different ex

I don't do this stuff, so this may be a stupid question. But it looks like you have p_A and p_B being independent in the posterior distribution. How does that work? I would assume that they're pretty correlated IRL --- we'r

I just want to point that your experience with Romania wouldn't apply to (almost) anyone moving there from another country with higher cost of living.

It's definitely brittle, but it's brittle along a dimension that usually doesn't change much over the course of the project (paper, book, etc). If you have automatically generated images or tables the benefits can be huge. `l

Some parts of TeX and LaTeX translate directly into a web setting, and I imagine it would be pretty straightforward to write an interpreter in Pollen/Racket that can process those parts of LaTeX files (cross references, bibliography ma

This, this, this. I used their (american) football data for a hobby project and it would take 30 minutes to an hour to clean one week's worth of games. Hypothetically, I found the sporting news to have much cleaner data.

There's more prefix notation in math than you think: ∑ᵢ xᵢ ∫ x² dx etc. And `A x` is more likely to be written as `(A x)` than `A(x)` in your example. I don't necessarily agree with the article, though...
