Re: A frame of a vector space that isn't a tight frame?

ahh, got it. I had just taken f(x) to be the signal in question, not arbitrary. Thanks!

A frame of a vector space that isn't a tight frame?

EDIT: changed the title to fix some ambiguity I am in the first few months of undergrad research and have been making my way for the past couple of weeks through wavelets and overcomplete dictionary learning Looking at the frame conditon: A{ \left\| f(x) \right\| }^{ 2 } \le\quad \sum _{ k }...

Re: Matrices with incoherent columns

I'm not doing compressed sensing specifically. I only started a couple of weeks ago, and my advisor's last students sort of wrapped up the project they had been working on, so I'm kind of looking for new stuff atm. However, her students had been working a lot with using Gaussian Mixture Models for v...

Re: Does this problem have an exact solution?

Assuming your answer is correct, there are actually an infinite number of solutions unless you specify the length of one or the other radius, since you have one equation, but two variables

Matrices with incoherent columns

I just started research in Image Processing, so I'm slowly going through the pile of papers that my advisor wants me to read. One is basically an overview of techniques to find sparse solutions to underdetermined systems of linear equations. The paper mentions that "for matrices A with incohere...

Re: Differential equations question

At the moment I really want to learn how to apply Calculus to analysis of video games -- so I can analyze any video games where many functions are unknown, but changes are visible, so I thought differential equations would help me do so. Well, calculus doesn't strictly apply to anything in a comput...

Re: The "IT DOESN'T WORK!" thread

Java references have pointer semantics. A = B means "A now refers to B" Yeah I thought it might not work because of that very reason, I was just trying to confirm that. In fact, it was some loose junk hanging around from my old (erased... oops!) BST file. I now get exactly what I expected...

So I accidentally saved a blank program over my Java Binary Search Tree class for my Data Structures class, so I'm rewriting it.

Re: My code has an English accent!

I am incredibly confused as to how this relates to an English accent & not just hard-to-read code.

Re: Confused why my code throws 'no return statement'

Two things: First, the '11' only comes from the explicit assignment, which requested "sets of natural numbers from 0 to 10, using an array of booleans". That's what the client wanted!!! :D Theres no reason otherwise why it couldn't be opened up to an ArrayList<Double> that could take basic...

Confused why my code throws 'no return statement'

So, for my Data Structures class, we have to do a little Set Theory. The implementation asked for by the professor asks us to replace the toString() in the Object class with a toString that outputs the elements of the set (constrained to Integers from 0 to 10) as numbers separated by spaces, or &quo...

Re: Tough Grad School Application Situation

Did any of the technical classes you took have a project component? That's a good way to demonstrate aptitude and interest, and a professor might remember you. Actually no. There is no formal engineering school at my college, so aside from a couple EE courses I took this past summer at JHU, my cour...
