Could someone please help me work through the differentiation in a paper (not homework), im having trouble finding out how they came up with their cost function.(adsbygoogle = window.adsbygoogle || []).push({});

The loss function is L=wE, where E=(G-Gest)^2 and G=F'F

The derivative of the loss function wrt F is proportional to F'(G-Gest)

Can't seem to figure it out.

Thanks

Emma
