Videos not in order

Hi
This video in not in continuation of previous video “Data Preparation”. Therefore concepts taught in this video bounced from my head. I think it’s a malfunctioning, a video is missing in this logistic regression series, so forward this to your technical team to add that video and if it’s not the case then request prateek bhaiyya to make a video which joins concepts taught in previous video & this video. Plus prateek bhaiyya’s has not explained the implementation of W(weight) and b(bias), that how he formulated their formula because as per my perception in initial video’s he has taught us the derivation for update rule in theta(for case of logistic regression).
So please make these things done as it’s halting my further progress in the course.
