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.
so true
Brit Freeman Watch Gilbert Strang for Filter Banks and Multiresulution Analysis
His writing (calligraphy) is the best I've ever seen. Really.
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.
This has got to be THE best introduction to wavelet analysis
Nathan the absolute lad. I took your courses years ago. Here I am coming back to refer to them for work.
You are truly an awesome teacher!! Such a fun lecture. This used to be such a boring subject for me. Now everything changed. I wish I can be as much animated about teaching as you clearly are. Thank you so much, Prof. Kutz!
Greetings from Pakistan. Best tutorial that I have seen on the wavelets. Greatly useful for a geophysicist like myself.
Geophysicist's party, I suppose) What did you do then with wavelets? Seismic, I guess? Maybe something like RGB mixing?
what a gem of a professor, sadly i'll never learn under him.
you literally are right now (when you watched this video)
@orti1283 under him as in he’s my academic/thesis advisor, not just listening to him speak.
@@dabulls1g I know what you meant, I'm just looking at the bright side :)
@orti1283 always nice to see the bright side
Thank you Prof. Kutz for your awesome lecture. It is one of the best lecture I came across regarding wavelet transform. As you are speaking, you reminded me of Chandler and Joey of Friends.
If my professors were half as passionate as this guy, then maybe i would fallen asleep on less lectures during uni.
totally agree, but genius is rare.
thanks professor. I have logically understood the WT and its background
AMAZING TEACHER! I tried to understand the concept behind wavelets through a lot of video but none was so well explained!
good timing to the class. Explanations are intuitive and rigurous, how a class should be!
Wow, that teacher is awesome!!!!. great class sir
Phenomenal professor, you have a new student. 👏👏👏👏👏👏👏👏👏👏
Very well explained. Perfect for a nerd during social distancing
The explanation is more intuitive since I had seen other videos. But this one integrates all of them or do i say this one is a summation of all of them. Nice Job Nathan. God bless you and your kids.
I have watched some of your tutorials, and they are all awesome, well explained and so clear.
Great lecturing on such a complex topic... You have made my exam preparation a cruise
Best wave at tutotlrial I have seen so far, very amazing teacher thanks
Probably one of the best brilliant professors.
you are such a good teacher its a fun learning from you huge respect!!
I'm doing my final year project on predicting churn in a Software platform and needed to find a way to represent user usage patterns preserving both frequency and time information. This is the first piece of information i found that explains wavelet transforms in a clear way.
I wish I was your student sir. Thank you so much for this great video. I learned a lot!!!
Nathan - thankyou, this is brilliant! I wish I found you ten years ago...
But this masterpiece came online only 3yrs ago.
Impressive quality! I could only dream about such a level of teaching at my uni(
Seriously, that cartoon is the key to understand the basics of wavelets.
Sir, thank you for this precious lectures. I and so many people, too would be grateful if you upload all lectures...
This is a wonderful tutorial. very good explanation. my regards to Mr. Kutz.
Great video. A very clear explanation of wavelets.
My weekend will be sand and wavelets with a beer for Dr Kutz. Daubechies looks like a harmonic reflection but it is doubtful I will integrate this thought.
Exceptionnal course, thank you immensly. I never understood wavelets before this video.
Man ... Wish I could explain like you and feel like ' yes that's how it works '
This is a great video. Amazing to understand the concepts...
Thank you very much Prof. Kutz.
Nice explanation
Very well explained, Many thanks sir, stay blessed.
Many thanks for this amazing video
best easy to understand
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.
What this video does is SHOW how to properly (so that everybody understands) introduce a non-trivial concept in mathematics / signal processing !
such a good video in understanding wavelets
This guy is amazing!!! Thank you!
This lecture is so amaaaazing, thank you!
This is excellent
Thanks Nathanlet.
Good teacher!
Thank you Nathan. Really appreciate it
best lecture on the topic.
Great teacher!
One of the best Tutorial on wavelet 😍😍😍
thank you very much sir. very nicely explained (time and frequency resolution (w vs t))
at ~ 18:50 would it not go up to sqrt(2) and -sqrt(2) bc we're trying to maintain the integral of the square of the function? Also, an amazing video and greatly appreciated!
I had the same thought
07:00 Isn't it Ingrid Daubechies though?
Great video!
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?
thank you very much. Please, i have a question: isn't the shifted parameter located in the center of the wavelet???
you are my god from now on Kreygasm
no such thing as know or what to sx or drax about it or shouldbarx, cepux, say/can say any nmw and any can b perfx
Thank you so much.
But how to get the frequency spectrum information from the wavelets? Kindly explain
Great video great teacher! Does anyone one where can I find the first lesson in this course? At tried the website, this video here is supposed to be lecture 2, but I tried lecture 1 and it is not introductory.
Thanks in advance
great explain
Great sir
Great! thank you so much!!!
why have a bar over the kernel in the CWT ?
Thanks a lot. Is there a lecture transcript? I'am a not a native English speaker.
Good stuff! But it remained unclear why the need for wavelet kernel instead of just sliding and scaling a window coupled with Fourier' transform?
So what is the difference between short Fourier Transform and Wavelets except in the choice of basis function?
Hi, Im very interested in getting more knowledge about wavelets, but I have a doubt, this wavelet content is included in the book: "DATA DRIVEN SCIENCE & ENGINEERING" (witch is in the link)?
Thanks for any answear !!
Great lecture, thank you!
This is the BEST explanaion of wavelets. Hats off and deep respect!!!!
Any videos about waveatom transformation
Great!
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!
THANK YOU SO MUCH!!
what camera were they using?
I wouldt mind going to a Hat Party with Professor Kutz
whre is donate to make more videos button?
I know you have students and maybe you want them to take notes but is it possible to include your notes or an appendix of the math.
Wtf I dont even need this theory still im watching it xD
Love this guy, he looks like he works on Wall Street in the 80s (no way this vid is of 2018) and fucked up, ending up teaching lol
سلام عليكم
استاذ ممكن سؤال؟
guys he mention something about multiresolution, do you know where in the video was it? I can't find it again
It is in his channel: th-cam.com/video/hAQQwvKsWCY/w-d-xo.html
22:48
wavelet > little wave … professorlet... abs(prof,i,j)/max(abs(prof,i,j)) = Prof. Kutz :)
I think someone needs to perform a wavelet transform of the opening scene of "The Master" and find the time and frequency aspects of Freddie Quell's life trauma! ;-)
I need any one help
I have to make the speaker level +200% to hear what you say
i love your jokes, if you were littel i would call you lill. nathan
Edwin gets absolutely destroyed in this lecture !!!
So this lecture proved that internet resources of this era do not give real intuitive understanding of the topic. Black board/white board is the only way of getting actual true knowledge
What do you mean?
@@gregandark8571 the understanding from the teacher in the classroom is only way to get actual concepts
@@sjyyoutube Oooh... ok.
Mexican hat is called sombrero.
you are hilarious
