if X is a random vector of size n following a multivariate normal distribution (each component of X follows the normal distribution N(0,1)). How would I prove that (X'X)/n converges to a definite positive matrix ? I don't even understand how such things can converge not to the zero matrix. It makes no sense to me.

It does not converge to the zero matrix. You have to look up the concepts of convergence in measure, convergence in probability, convergence in distribution, convergence of estimators of population moments. Mind that sequences of samples do not behave like sequences in real analysis. Here we're talking about probability.

I'm sorry if this is the wrong thread, but I'm a desperate, clueless idiot who needs help with their homework:

given: training data set with 2 different labels
task 1: apply batch stochastic gradient descent and calculate the "weight vector" theta.
task 2 (what I'm struggling with): plot a separating plane between the data points given.

I have this vector theta but I'm not sure what exactly it predicts in the context of logistic regression or how to derive the plane from it.

Most grateful for any hints in the right direction.

Your weight vector theta should describe an affine hyperplane, which can be used as a separator between your two categories of points.

Eg: you have two features (x and y axes), and you've obtained that theta0 = 1, theta1 = -3 and theta2 = 7, then you need to draw the line defined by the cartesian equation 1 - 3x + 7y = 0. If this doesn't make sense to you, check Andrew Ng's course on ML, and his episode(s) on logistic regression.

thank you for the reply!

in my scenario, there are 3 features x,y,z, and the weight vector has actually 4 values (1 was added for the multiplications, and I think the intercept - I forgot the actual explanation).

So, I'm struggling with transferring on how to take these 3/4 inputs and get my z's.

Is it possible that the plane is just defined by z = theta0*x + theta1*y + theta3 and I leave the theta2 out?

will check out your recommendation!

If you have 3 features, each data point is defined by a vector inside a 3D vector space. Your number of columns on your Excel spreadsheet / numpy array, etc, is the number of dimensions.
Each point can then be represented as a shape that stands for its category. Say triangles for points which resolve to category A and circles for points that resolve to category B.

Your separating space between your cloud of triangles and your cloud of circles is always an affine hyperplane. Hyperplanes in 3D are just simple 2D planes (hyperplanes are spaces of dimension n-1 in a space of dimension n). The cartesian equation for a 2D affine plane in 3D space is "t0 + t1 * x + t2 * y + t3 * z". Affine means "not passing by the origin", and that's your t0 constant term that allows this fact.

Download Geogebra and play around with cartesian equations in R2 and R3. Reading your response and seeing your confusion, I think you'll need it.

- that your prediction takes into account theta0 (with a column of 1s at the left of your X data matrix, or by adding the theta0 at the end for each line of your matrix product X*theta (equivalently each coordinate of your y_pred vector))
- that your prediction X*theta does indeed call expit aka the sigmoid function (if you just copy-pasted your linear regression code like a baboon)
- that your log loss aka cross entropy function calls the correct loss value for the appropriate prediction (-log(x) or -log(1-x) for 1 or 0)
- that your gradient descent algorithm is correct, and that your log loss is indeed decreasing at each cycle/epoch
- that your hyperparameters (alpha, lambda, etc) are evolving smoothly as expected, and not fucking things up

That's off the top of my head the most common mistakes to avoid.

do you have an undergrad?
become a top tier researcher? too late.
that means top universities are closed off too.
if you really want it and stick with it for the next 10 years you can probably become a professor at a community college or small state school.

now some may say X person started late, or you can do whatever you want if you put intm enough effort. my response is:
1. this may have been possible in the past but academia has been careerized. everyone is in constant competition and time and energy are not on your side.
2. learning math/physics at that level require a ton of time and energy. at that age you start having to worry a bit about health and money and going to the dentist etc. all that distraction make it hard.

what matters more and more for professorship applications is the academic output relative to your academic age. and you only start counting after your PhD. So, if it really is your dream, you're not too old necessarily, but you really need to get going.

He is actually 100% correct, and I'm 24. I am working with some younger 18,19,20 year olds who are motivated to work day and night, to get their king internships, work day and night there for a good offer etc. You need the same attitude to get to the top academically.
In your mid-twenties many people start to focus more on work-life-balance, not "wasting" your twenties. You're not as money/career obsessed anymore, as those are just proxies for sex and a good/happy life. when you'll get to know more people that work 25h per week from the beach you're less eager to work all night in the office.

Okay, I'd recommend refreshing first on elementary algebra. This is extremely important and one of the reasons students struggle with any future math classes is they don't have their algebra down. You could pick up any book really (something with a lot of exercises) and just start going through that. For this I suggest:

Serge Lang Basic Mathematics
or any standard textbook on elementary algebra you can find (with solutions so you can test your understanding)

I think that's a good start. Then you should look into precalc and refresh on trigonometry. I'm not sure if you want to learn proof based mathematics or stick with more computational mathematics. I'm assuming that you would be interested in learning proofs so I'd suggest you get "Book of Proof" by Richard Hammack and do every problem in that until your eyes bleed. The boring in anything is always kind of dull but it's really important to get the basics down.

That's very bad. The exercises are as important if not more important than the rest of the text and can save you a lot of time. I used to be like you, reading books without doing the exercises and I've got to tell you that as uncomfortable it is to actually do the exercises and as tempting as it seems to just move on and learn new interesting stuff, doing the exercises will save you massive amount of time because you test what you actually understand, notice the holes in your understanding and also get better at problem solving.

A lot of problems are a waste of time, I mainly refer to problems that won't provide anything meaningful that you don't already know, you'll just solve them like a robot, you need to carefully read and select which problems are worth spending time on.

This is stupid. Beyond high school where all the problems are essentially the same, all problems are worth solving. There are usually that many problems in a textbook. If it's actually trivial you're only going to spend 1-2 minutes on it. You might think it's trivial at first but later when doing it realize it's actually not that trivial, which will be a great learning experience. In any case, the minuscule time you save by not doing problems you deem to be a waste of time before even doing them pales in comparison to the time you could save actually properly learning the material, doing all the exercises and not leaving any gaps. Exercises are there to save you time, all of them.

I have something to say. Math is a god tier degree, but only if from a top uni with experience in other areas. Also most high paying math jobs can be found in banking. My brother who studied mathematics from Oxbridge is making tons now working at an investment bank in London.
If you can't find a job with a math degree, you're either shit at math or have zero background knowledge.

This might belong in /sqt/ (it's a question about Taylor series) but it's in a more advanced context of asymptotic analysis so I'm asking it here. pls forgive me bigbrains of /mg/

The prof sez we have some polynomial $p(x)=x^2+\varepsilon x - 1; \varepsilon \rightarrow 0$ and $\varepsilon$ is small. So the corresponding problem $x^2 - 1 = 0$ for $\varepsilon$ equal to 0 obviouslyl as solutions of $\pm 1$ .

Now since $\varepsilon$ is small, we can expand it as a Taylor series. This is what I don't understand, exactly, or at least the notation is unfamiliar to me:

For the positive root: $x = 1 + \varepsilon x_1 + \varepsilon ^2 x_2 + ...$ So we have $x^2 = 1 + 2 \varepsilon x_1 + \varepsilon - 1 +$ some higher order terms.

None of this is so bad so far, although I find the notation unfamiliar, I at least "get it" from a computational perspective, we truncate our little Taylor expansion and anything with $\varepsilon ^2$ as a term gets shoved into "higher order terms" as we compute the relevant Taylor series for the polynomial, with the knowledge that x = 1 at some point and our ability to manipulate what is assumed to be a convergent Taylor series to reconstruct the polynomial in terms of the convergent Taylor series. (Please correct me if I'm wrong about that.)

What trips me up is he then "collects terms in $\varepsilon$ , with $O(1): 1 - 1 = 0$ $O( \varepsilon ): 2x_1 + 1 = 0 \rightarrow x_1 = -0.5$ $O( \varepsilon ^2): x^2 = (1 + \varepsilon x_1 + \varepsilon ^2 x_2 + ... )^2 \rightarrow x_2 = -.125$

So somehow we get a system of equations that gets us some terms $x_i$ which gets us an approximation of the solutions of our polynomial in terms of a given $\varepsilon$ and we can check these approximations against the quadratic formula and figure out how our relative error works. Right?

How can I wiggle my way into studying math full time without breaking the bank? Is it possible, or should I resign myself to self-study if I'm not into the idea of shelling out $$$ for a master's? Can I somehow spin the shit out of my work experience and couple that with good test scores and get into an applied department?
Background:
I did the wrong sort of math degree in undergrad (applied, very few proof-based courses).
I'm coming back to actual proof based math and really loving it (mainly Tao's Analysis because I don't have time for much more than 1 book).
I'm 24, I've been in industry for 4.5 years, mostly software and data science but also loads of non-quant work (and let's face it, day-to-day software/data science is not very thoughtful).

Not entirely sure, but I would still say it's very unlikely to spend a career doing research in statistical theory. If you're fine doing applied research or if you just want to fuck off to industry it's another matter. But if that's the case just look into what your local polytechnic school has, and be aware that what you're going to be doing won't be mathematics, but programming.

Depends on what textbook. Lower level book like a linear algebra or calculus text? An hour seems reasonable. Something like a graduate level algebra text can take hours depending on the content.

An hour is a bit ridiculous. Honestly, it depends on the topic and how dense it is. For example, electronic circuit theory could take 6-7 minutes, but calculus could take 15-20.

I stopped doing school work in the 5th grade, but now I'm trying to actually move into some career I'm mid twenties and I got to move out the warehouse before the robots replace me in the next 10 years. I don't "get" math. Some of it makes sense as I can envision it in the real world, but others I can't grasp at all. It seems to be almost made up and we just agree it works and it irks me. Also I'm doing Algebra 1 on khanacademy, but should I just go on to Geometry so I can move into Algebra 2? I want to ace the CLEP so any typs. Also thanks for reading my blog.

Different version of the same question:

The sine and cosine of a rational angle are always algebraic numbers, but a non-rational angle may have algebraic sine and cosine as well.

Given the sine and cosine of some angle, if we know that these are algebraic, and we know what polynomials they are the roots of, can we somehow tell whether the angle was rational or not?

To clarify, a rational angle would be something like three fifths of a full circle -- any angle that's rational when expressed in degrees.

Let $z = \cos \alpha + i \sin \alpha$ , this is still an algebraic number.
If you have the minimal polynomials for $\cos \alpha$ and $\sin \alpha$ , then you can also figure out the minimal polynomial of $z$ .
Observe that $z$ is a root of unity iff $\alpha$ is a rational multiple of pi. So you just need to ask yourself "is the minimal polynomial for $z$ a cyclotomic polynomial".

Then I would recomment something where you can draw what's happening, like the triangle inequality. Had very good experience with these kind of exercises in a course that I one did the exercise classes for. It was however more about basic geometry, finding exercises outside of real analysis about inequalities is kind of hard. If I come up with something clever I'll post it.

>Beyond high school where all the problems are essentially the same, all problems are worth solving.
Gonna need some elaboration on this one. I used to want to do all the problems at the end of sections, but I noticed diminishing returns rather quickly. E.g. "find the equilibria of the following systems" and it's 10 questions or so of different (but unenlightening) systems. Usually just do the last problems of a set, which are usually the most difficult. That and it depends heavily on the text you're reading. Baby Rudin, for example, has a lot of exciting and challenging problems. More textbook-ish books like Strogatz repeat themselves a lot as in the aforementioned example.

Fuck khan academy, and don't bother separating algebra/geometry/trigonometry. Read Precalculus by Stitz And Zeager. That single book will cover all you need to know about algebra, geometry, and trigonometry and is very worth the read. That book alone will teach you everything you need to know before starting on calculus.
Fuck "algebra 1" and "algebra 2", it's just algebra, and this book will teach it to you. It is available for free online.

How much do you like philosophy? I loved it, and I wouldn't end up trading the education for anything. I ended up teaching myself the bits of a CS education I needed, and I was completely fine with that. Philosophy is almost impossible to learn well on your own. CS isn't, but do you really want to put in the time later if you need to? Does philosophy matter that much to you?

I think it honestly depends how committed you are re: going to grad school. I finished a CS concentration during my first year and it was nice having a $200k+ starting job as a backup if other avenues didn't work out. It's in some ways the best 7-8 course investment you could make.

And I actually disagree with the other poster. Philosophy is definitely something you can study casually as a hobby, far more than a stem field actually. Maybe just take a few history of philosophy courses to get started with basic background.
