Hey, I’m actually interested in statistical learning theory in grad school. What kind of math prerequisites do I need to be able to research statistical learning in a phd program?

A basic course in statistics and the desire for the PhD grind.

Dude cmon stop playing. I’ve read some of these papers and the math is crazy. What math courses do you need

I kindda agree that you don't necessarily need a "math course" other than the usual requirements of CS undergrads. You somewhat pick up the rest on the way. I asked the same thing to theory grad students and they said the same thing. One fella that had a math BS actually said he didn't find his undergrad experience to be terribly useful, which kindda says a lot. Taking actual learning theory classes and reading textbooks will be necessary though.

That doesn’t make sense tho. Math majors have more theory than cs majors. Statistical learning definitely requires high levels of mathematics, like functional analysis. It’s a huge area in statistics.

The thing is, you can't learn everything in advance. And you don't need everything all the time. Some works in learning theory might be mathematically very deep, but taking a few undergrad math courses definitely won't prepare you for those. Although they might help you develop mathematical thinking. But as per the knowledge itself, I don't think taking math major courses is the most efficient way to do it.

So then your saying a cs major is the best major? All they learn how to do is code? How would you not need mathematical maturity to even make contributions to statistical learning theory. Like I would even argue a statistics major is more prepared than cs cause they have the background in stats with computing experience as well. Cs is just a software dev major.

Because you do learn theory in undergrad CS...? On the contrary, no course teaches you how to code.

Yeah you learn systems design, not functional analysis, measure theory, and actual mathematics to do the derivations in statistical learning theory. Statistical learning theory is mathematics. Not just coding.

You learn algorithm analysis, computational complexity theory, discrete mathematics, automata, cryptography and whatnot. Do these seem like coding to you?

None of those are useful for creating new statistical learning methods or pushing the boundaries of statistical learning as functional analysis, measure theory, real analysis, and statistics. Like cryptography is useless for developing new regularized regression methods, who gives a shit about complexity theory? Like you guys think ML theory and statistical learning is a CS branch. Like you guys coin the term machine learning and think it’s a branch of CS… very far from the truth. Mathematicians and statisticians have been running circles around you guys doing this for decades. Know your place

Wait what? The core of learning theory is algorithm analysis and complexity theory! Please take any learning theory textbook or course first before making such groundless judgements. God the freakin definition of "PAC learnable" is algorithm-theoric.

It’s literally called statistical learning theory

Red-Portal t1_iti13ms wrote

Yes that's why you need at least "undergraduate" statistics knowledge.

Lol that’s so false. Undergrad stats is not nearly enough, not even undergrad math. You can get away with just knowing how to code a little bit but it’s way more math and stats. Cs majors are just trained to be software engineers and nothing else. I’m a math and stats major and run circles around them in AI courses because they don’t have any technical depth mathematically.
