Derivative of 2 norm
WebAug 1, 2024 · The reason this looks different from other norms is that at most places, $\infty$ norm depends on just one coordinate; the derivatives with respect to other coordinates are zeros. This isn't as easy to describe … WebOct 23, 2024 · So if we’ve included a norm in our loss function, the derivative of the norm will determine how the weights get updated. We can see that with the L2 norm as w gets smaller so does the slope of the …
