A doubt when applying gradient descent on logistic regression

JJaassoonn · June 3, 2023, 3:27pm

Dear Administrator,

Could you please guide me on this issue?

According to this lecture slide,

We have a cost function here,

We need to diffentiate the cost function before applying to gradient descent

I have tried many time but still couldn’t get the derivative as same as the result as shown in lecture slide

May i know if there is any solution?

Thank you.
