Hello Binod Sir, Your videos are amazing and to the point. I have an exam question related to NN, which I am not able to solve it. I want to ask that question to you, please let me know where I can post it. It has a diagram so I cannot post it here.

Thank for the helpful video. I have a question that why there are two paths to update b1. It should have 4 paths because there are two sub-branches at the sig(h1) and sig(h2). Thank you

Hi Vinod ji,

Very nice tutorial. I follow your Deep Learning tutorials regularly.
I noticed at 10:30 and later that for the partial derivative of Sigmoid of x w.r.t x there should be a -ve sign in the numerator. Please check this up.
Thanks very much and Regards,
Krish
