Problem in week 3 practice lab : logistic regression

Hello everyone,

I met a difficulty in logistic regression. I do not know how to resolve it. I do not know if there is any code error. I will be grateful if you can help me fix this problem.

Hello Penghao, welcome to our community. You didn’t accumulate the value for z_wb properly, and you might take a look at how you accumulated dj_dw[j] for reference.


PS: We can’t share assignment code here so I am removing it.
