Hocam allah razi olsun. Bir tane subgradient anlatan duzgun video bulana kadar gotumuz catladi. Tesekkur ederim

From Fourier to Z transform to SVM's... Prof, you are great.

Can the subgrad result in a no descent direction?

after we get the optimized w, how to get the optimized b?

Thank you so much sir, after studying svm i wondered how actually can we find optimal W , your video gave me an answer for that.

hi what happens when we compute the gradient for one data point?does it finsih all the point or pick a random point?

great video! I just don't get your intuition for choosing any value you want within your constraints.. whats stooping me to choose -d*x_i instead of zero in 9:37 and maybe get different result in the loss function that can potentially dramatically change my result in for example to classify corona sick people or not

That's called subgradient NOT subderivative. The subderivative is a taken name for the dini derivative look at Rockafellar and Wets book.
