It's likely that humans evolved genes for social anxiety as a self-defense mechanism against you getting attacked by the mob.

What are your favorite genes?

It actually does the opposite for me, I feel that anxiety makes one more vulnerable since they display signs of weakness.

so they use a wrapper for Fortran libraries, but they don't use Fortran? Fuck you retard. You have any idea how much faster Fortran is without Matlab sitting ontop of it? My estimate is thousands of times.

I do all that you explained but on EverNote, a basic multiplatform note app which I use since 2015. Business ideas, to do list, a small encyclopaedia of scientific techniques in my field, useful links...
If I were to start it all again I would go to Obsidian because of the interactive network functions. But I feel like it's not a big deal to not have it.

I've used Evernote in the past as well, but I just never stuck to it for some reason. Only after Obsidian did I really start expanding more.

I guess it's something like the idea that a quadratic convex optimization related equation can be solved by reducing it to some kind of linear convex optimization problem, but what specifically is it that makes it efficient?

>>14301253
Its been awhile since I looked at the formulations for SVM, but in general optimizing convex functions over convex sets is efficient because local minima <--------> global minima. There are different algorithms for solving this, one example is you can convert a constrained optimization problem to an unconstrained one by penalizing constraint violation (see barrier method), then you can optimize the unconstrained problem using you're favorite flavor of gradient descent.

Lol this is vague and doesn't mean anything. What the professor means by "strong mathematical intuition" is probably his polite way of referring to intelligence and insinuating that you might not have it. I would confront him that and then just disregard his passive aggressiveness. He probably hates his career and is trying to dissuade others while he makes all the big bucks.
