COURSE WEBPAGE: Inferring Structure of Complex Systems

This lecture introduces the wavelet decomposition of a signal. The time-frequency decomposition is a generalization of the Gabor transform and allows for a intuitive decomposition of time series data at different frequencies.

Man! Kutz's students are a lucky bunch. The guy is clear, concise, insightful and fun. Great presentation of the material.

So amazing. Best Wavelet tutorial on youtube. I've been watching a lot of these introduction to wavelet videos here on youtube, and all of them jump directly into the math without giving an basic understanding of what's going on intuitively. Really appreciate this.

I've been playing around with trying to understand wavelets on and off for years, but something was always slightly missing. This is one of the best lessons I've seen yet. I wish I had professors like this at Uni.

A video about a method that can be used for data compression (compresn): We can see that data compression was used on the video. the black lines have very white lines around them, then slightly grey lines around them, then back to average, which is very slightly grey. Clipping.

@MrAmalthejus
@MrAmalthejus 2 года назад
So after multiplying with the Mother Wavelet we still need to take the Fourier Transform of the answer to extract the frequency information,right? Just multiplying a signal with a Square Function doesn't transform it into any domain, does it?

It seems like it's not super-important to have true compact support. Mexican Hat Wavelet doesn't really have compact support; it extends forever in both directions. PS great video - one of the very few understandable wavelet vids, thanks!
