Everything is so clear as you pinpoint all the remarkable details one should think about, and as you make mathematical steps reveal their simplicity ! I discovered your channel a few days ago, and I've made so much progress in understanding those fields of digital signal processing and machine learning. I'm in academic and teaching too and want to emphasize the very good and effective job done using only hand-made drawings and hand-written text. You reveal that knowledge is always easy to propagate if one wants to put effort in the process. Thank you so much, keep up the so good work, please ! You're a must see channel !
Sir, you are the best tutor of signal processing on youtube ever. I am working on implementing voice recognition task (embedded) based on AR coefs and you are helping me a lot! Thank you very much
Mr. Barry Veen you're wrong! Yule-walker equation has no error to be associated with it because random process associated with yule walker may only be characterized statistically and the values of x(n) are only known in probabilistic sense thus the errors that are minimized for deterministic signals are no longer appropriate. In fact if you look at the yule walker equation itself, there is no variable that tells you about model error variable.
Thank you. You'd saved my life once again. By the way, I frequently saw this topic together with its stationary property which I don't understand at all. Would you mind give me an insight about the stationarity thing?
Misguided. Beware. Since Yule Walker equation has no model error, to get the least square Yule Walker equation, we need to increase the # of autocorrelation values NOT the N poles.which is dependent of the application. The example Mr. Barry Veen gave is totally wrong and misguided. You need to understand what Random Process is to know what Yule Walker

Thank you for doing this. It was driving me crazy figuring out how to solve for the coefficient parameters.
Hello, is it possible to fully send or create another video for this example including MATLAB codes? Behind this, video is great thank you.
@4:42 why when L = 0 we have Sigma square on right hand side ?
@3:10, shouldnt ao =-1 or all the other ar parameters are their negative.
if you start from y[n] = sum_k a_k y[n-k] + w[n], then you need to take expectations to get an equation relating the covariance of the data
are LPC and Auto Regression different or same?
Your video is so helpful! Thank you so much and keep on posting awesome SP videos!
Can the Yule-Walker equations hold even when we do not assume c=0.?

can someone please, help me to code a function to estimate the autoregressives parameters in c++?
Thank you for explaining this so well.
thank you sir, Sir, could you help me how to determine modeling for for filters using ARMA methods
Sir your great.....and thnx for making this video...🙏🏻
Thanks for your video, it is very helpful!
Very great video. Thanks!

what if we wanted the prove that ry[n]=Sum ai*ry[k-1] is valid for AR(p) Should we need to take expectation?
clear and precise, thank you sir.
Great video, thank you very much!
Thanks a lot mr :)
Great video. I am confused how he derived x[n-l]= - sum a_k x[n-l-k]+w[n-1] and R_ww[k] = sigma^2, k=0; 0 , k =/0
Thank you sir.
