Once again you are providing an excellent high level overview in very simple terms (for the mathematically trained). Really enjoy your videos.

I'm currently studying a Phd and your work and videos really inspire. Thanks for this great video series!

Today is a GREAT day! Profesor Brunton upload a new vid :)

I have never come across this...what a powerful idea! You are doing a great job covering it. Thx

You are a legend steve. I dont care about this method but still watch it because you make it interesting and understandable

Thank you for all your videos. This is how all professors should give a lecture at university.

I've been reading up on compressive sensing literature (e.g. by Richard Baraniuk et al.), and they are really hard follow for a math lightweight like me. Your explanations are so much clearer. Looking forward to see more in this series.

Thanks a lot! Cant wait for next lecture! Greetings from México 🙂

Thank you so much for making this. This helped me a lot. Please make more videos on compressive sensing. 😊

great!!! cant wait for the next lecture.

Love it! Why Does anyone need Netflix :)

Love this topic series

Love this guy!

Hi Professor, I have a question about the measurement matrix C. I see in literature that most seem to portrait it as a dense random matrix, not a spiky one on each row as you show here. So I guess you show C as a spiky matrix, just because that it is incoherent with the Fourier basis so it would function as well as a dense random matrix? I think I was confused originally when I saw you (in one of the previous video) taking random data points in time domain for super-positioned sine-waves, rather than taking random "combination" of all data points in time domain (which a random matrix would do). So, hopefully my above understanding is correct. Thanks for all the videos!

Good morning Professor, Thank you for the nice videos. I have one question though: why do we want "the sparsest" s to be our solution? Shouldn't we look just for the "right" s? How can we claim that the sparsest s is the right one? Thank you, Matteo

Hi Professor, had a question regarding the equivalent formulation. Could we also reformulate the original convex problem as minimization of (L2 norm) ||Θs-y|| subject to constraint (L1 norm) ||s||

Is the sparsest solution to the underdetermined problem unique?

is x here represents the compressed version of the original image since we are inferring the "active" Fourier coefficients? So it shouldn't be the high-resolution image. Am I correct?

Hello, thank you for this great lecture. I have a question, in the equation (y=C.x ) isn't possible that there are many xs that give the same y? Thank you in advance.

1:45 do you mean underdetermined or undetermined?

Extremely relevant insights into the topic, professor. Thank you for discussing these.

SIR COULD MAKE VIDEO ON USING KALMAN FILTER WITH C++ LANGUAGE OR PYTHON

Is this somehow connected to LASSO and Ridge regressions? Love you videos! Thanks a lot!

but what if we have s and we want to find the right fourier basis?

Hey please add the code for image compression using DCT,FFT,Wavelet

Thanks for this video ok

I appreciate you making videos on this topic for the not-so-bright people like me. I'm fine with utilizing math, but when that math is presented without context it drains all life out of me.

Thank you very much for your complete and helpful explanation. If possible, I would like to have your email and ask you some questions.

I can't work out the transformation that he is using to write on the board 🤣. He's writing in reverse, right?!! :-O
