MUST WATCH....for electrical engineer....

very nice
-
Really enjoyed the lecture but all the images and videos were quite distracting. I found they actually ended up reducing the impact of what was being said.
-
@albedoshader All right then ;-) It indeed sounds really French.
-
I saw this for the first time a few years ago, and I thought it was brilliantly done. I was really glad to see it was still findable. I admire your ability to explain such a relatively complex topic in such an approachable way. If all teachers were so humble there would be a lot more scientists and engineers in the world.

@naxelas: I didn't mean she's Freanch but her surname is. :) Sorry for my imprecision. I should have said: the name "Daubechies" is French.
-
@albedoshader Daubechies is a Belgian and American (naturalised 1996) citizen. She speaks French but is in no way French.

Thanks, a great presentation!

Nick1Nap,
Is there specific Daubechies to heart rate variability analysis using wavelet tranform?
lperandini 3 years ago
This is something you probly checkout through published articles. Someone probly has gone through this type of analysis examining the best topology. There are other wavelets besides Daubechies. They should be examing orthangonality, symmetry, and other topology components of the waveform.

mother wavelet choice is subjective and hence bullshit. Get off the fashion bandwagon and embrace stft

STFT are good and sometimes thats all you need. You dont need anything fancy. HOWEVER, Using a STFT you have to know what the size of your window is going to be! Wavelets you dont! It is obvious you didnt get the symbolism in the beginning and end of the video. One of the sayings with the wavelet transform is that you can see the forest and the trees. This saying implies the use of the multiple windows that abide to the Heisenberg Uncertainty Principle .

Additionally, if you really want to get technical, there are nonlinear wavelets but thats a whole new can of worms. STFT is quite inferior to wavelets but sometimes you dont need something so technical to solve the problem at hand. Its obvious that you really cant handle something so cumbersome.
P.S. Even though your opinion is unreliable and invalid..I value it. THANK YOU but try cracking a book!
