Hi @Mubsi ,
Lab id: jfxmpusrcheo
Can anyone please help me with exercises 4 and 5? I tried many times but did not get the solution. I will appreciate your help and support.
Hey @Mahnoor_Shafiq,
Can you please share your error stack, or in other words, the error that you are getting, in exercises 4 and 5?

After some changes now I am getting this error.
Can you please help me with this?
Hey @Mahnoor_Shafiq,
Did you cross-check your equations with the ones given in the lecture video? Let me give you some starting hints. For computing grad_b1, as per the equations given, we don’t need W_1, still in your code, I can see that you have used it. Similarly, for computing grad_b2, I can see that you have used H^T, still it’s not used in the equations given. Re-check your equations once using the ones given in this lecture video as a reference. Let us know if this helps.
Cheers,
Elemento
Hi,
Hope you are doing well. Sorry for the late response. Thank you for your help I checked the lecture and I was able to solve the issue. Thank you for your help again.
Hi @Elemento
I’m also stuck on this issue.
Could you please advise me on what the ‘step’ function implies here:
Also, the formula for gradient of b2 is missing in the slide in the latest version of the video.
I could not find it in the lecture notes as well.
