Hello,
I am having issues with Graded Function: Compute gradient code. I can’t figure out where the problem is and I’ll be grateful if someone could help me find solution.
The figures I get are not what is expected. Image Uploaded.

Hey @Daniel_Ferrada,
Can you please DM your code for the compute_gradient function to me? For DM, click on my name and select “Message”.

Cheers,

Hey @Daniel_Ferrada,
Check out the below line of code in your implementation of the compute_gradient function;

dj_dw[j] = dj_dw_ij

It is supposed to be;

dj_dw[j] += dj_dw_ij

I am assuming this is a typo on your side, and doesn’t require any explanation, but if it does, do let me know.

Cheers,
Elemento

Ah!! of course. It adds another value to dj_dw[j].
Thank you!

Hello @M_A_Naidu, we are not allowed to share assignment code here, so I have removed it. I am closing this topic.
