Which of these courses should I pick as an elective?

>Logic
>Combinatorial Optimization
>Applied Algebra (Cryptography)
>Advanced Statistics
>System Theory
>Decision Theory

I don't know what half of these are about.

you seem to be having trouble deciding on things, why don't you take decision theory

I took a course titled bayesian statistics and decision theory and found that it was very basic.

a LOT of the course was simply common sense.

in most cases you simply choose the option which has the highest expected value.

And when that expected value is too hard to calculate they just throw their hands in the air.

It turns out that if you really want to be able to make the best decision in anything but very basic, rudimentary, easy situations, what you have to know is optimal control theory , of the stochastic dynamic programming flavour.

Take the real abstract algebra course.

My main interest are analysis and probability. Unfortunately, the "Advanced Probability" course is only for 3rd year students, and I'm second year.

Decision theory is the best choice.
Hint: it's all about maximizing the expected value of an objective function, usually with stochastic dynamics

Sounds interesting, thanks anon.

I'd strongly recommend against that.

If you're a second year student the """decision theory """ problems you're going to cover will probably be very basic unless it considers the simplex algorithm to be a pre-requisite, then you can get into some useful decision making under uncertainty problems from operational research.

otherwise it really will be mostly common sense baby shit like "hurr how much would I be willing to pay to [some basic expectation value problem]" .

It sounds like they almost certainly won't do any dynamic stochastic control which is what you need for most problems where you have to determine the best policy rather than determine a single decision.

honestly if you're at all interested in probability and analysis you should probably just do 'advanced statistics'.
