Chain rule for vector functions
Web13.7: The multivariable chain rule The chain rule with one independent variable w= f(x;y). If the particle is moving along a curve x= x(t);y= y(t), then the values that the particle feels is w= f(x(t);y(t)). Then, w= w(t) is a function of t. x;yare intermediate variables and tis the independent variable. The chain rule says: If both f x and f WebWell, the chain rule does work here, too, but we do just have to pay attention to a few extra details. Let's start by considering the function f(x(u(t))), again, where the function f takes the vector x as an input, but this time x is a vector valued function, which also takes a vector u as its input.

WebNov 12, 2024 · Rather than the chain rule, let's tackle the problem using differentials. Let's use the convention that an upppercase letter is a matrix, lowercase is a column vector, and a greek letter is a scalar.

WebApr 12, 2024 · It's this rule above that we directly employ in the above solution, by expanding the loss function in terms of its scalar variables, y ^ [n] \hat{\mathbf{y}}[n] y ^ [n] and y [n] \mathbf{y}[n] y [n]. However, students also learn that a similar chain rule exists for vector input/output mappings.
