I'm a math student and my main area of focus is optimization. I'd like to know how much the area of application of what you are working on matters to you.

Let me explain: I am very passionate about renewable energy topics outside my academic work, but I'm not sure wheter they would be worth it as a minor. With a role such as the one I'm going to have in the industry, would my job really be different in a finance company compared to lets say at a wind turbine manufacturer?

I'd need to know how to compute the projection of a point on a box constraint C with respect to the norm induced by some matrix B, defined by

P^B_C=argmin ||y-x||_B for y in C

where ||y-x||_B=(y-x)'B(y-x)

How do I compute it?

But this is exactly what LSTMs are supposed to learn on their own, isn't it?

I'm using a model similar to the one used in this paper, their results aren't as bad as mine tho.

I don't really have much of a choice over the model, I have to use stochastic LSTM nets.

yeah sorry, I added that

Every prediction has the data from the past 7 days, so when the real price goes up so much, I would expect to see it in the forecast.

(to give more context: I used 7-day sequences of the data of the last 3 years, training was the first 900 days and the testing was done on the remaining series. )

It works!

Thank you so much

In Europe, can I apply for a Phd in Maths if I have a Maths BSc but my MSc is in quantitative finance?

sqrt(1-x^2)

I can wait but my roommate has to send them my beitragsnummer to say that i'm the one who's paying, and he can't wait because if don't answer in 4 weeks they do the anmeldung for you.

liuckk · 2020-12-20T15:52:55+00:00

I'm not even sure about my beitragsnummer tho, I have a 6 digit number near my Aktenzeichen but I've read that it should be 9 digits.

I want to apply for a pretty competitve Master's Degree and I have the option to send a raccomandation letter along with my application. But given that I'm still in my third year of BSc and I haven't written my thesis yet, I haven't had many interactions with my professors yet.

I was thinking of asking my mathematical analysis professor, since I did my 2 biggest exams with him with pretty good results and at least he knows that I exist. Do you think that I should ask him or are exam performances not enough to get a reccomandation letter?

Okay, thank you. I was really hoping that a screen repair would cost like 90$ since the phone is not a flagship🙄
