We can use the chain rule with other rules that we have learned, and we can derive formulas for some of them. The chain rule combines with the power rule to form a new rule: Ifh(x)=(g(x))nh(x)=(g(x))n, thenh′(x)=n(g(x))n−1g′(x)h′(x)=n(g(x))n−1g′(...

I prefer to see the chain rule on the "per-wiggle" basis:x wiggles by dx, so f wiggles by df, so g wiggles by dgCool. But how are they actually related? Oh yeah, the derivative! (It's the output wiggle per input wiggle):

Chain Rule for Derivative — The Theory https://ift.tt/2YDoEwS About 0 Minutes In calculus, Chain Rule is a powerful differentiation rule for handling the derivative of composite functions. While its mechanics appears relatively straight-...
proof of the chain rule Proof of the Chain Rule •Given two functions f and g where g is differentiable at the point x and f is differentiable at the point g(x)=y,we want to compute the derivative of the composite function f(g(x))at the point x.In other words,we want...
1, in accordance with the chain rule: $$ P(w_1,w_2,\ldots ,w_{t-1},w_t)=P(w_1)P(w_2\mid w_1)\cdots P(w_t\mid w_1,w_2,\ldots ,w_{t-1}) $$ (1) Probabilistic language models mostly approximate Eq. 1 by \(P(w_t\mid w_{t-n}\), ..., \(w_{t-1...
