I'm trying to understand the usage of w,x here. I have to find the partial derivatives of the function to form a matrix later on. But w,x seem to have odd <> symbols around. Can somebody explain what this part -<w,x> means?

@MartinR Ty so much of that. Any suggestion on how to use dot product here to find derivative of the above equation? – Sabbir Ahmed Nov 12 '21 at 12:48

What exactly do you want by differentiating the function? – Laxmi Narayan Bhandari Nov 12 '21 at 14:16
