Gradient of W§W matrices


Hey !

Would be grateful is someone could share how to compute this gradient :)
Got it completely wrong !

Thanks !

The key is to note that in the sum below, if i is not i' and j is not j', then no term in the sum will be Wi'j', and thus the derivative will be 0.

Hope this helps

You rock

Can you please mention which one of the choices is the correct one?

the 2nd !

I kind of guessed this one by looking at the dimensions that the derivative would need to have (NxN): it left two options still though :D.
