1.5多元复合函数的链式法则(the Chain Rule of Multiple Composite Functions) 微积分是人类智慧最伟大的成就之一,它以函数为研究对象,以极限为理论基础,微分是‘无限细分’,积分是‘无限求和’.而无限就是极限。 微分和积分的思想早在古代就已经产生了,古希腊的数学
We can now apply the chain rule to composite functions, but note that we often need to use it with other rules. For example, to find derivatives of functions of the form h(x)=(g(x))nh(x)=(g(x))n, we need to use the chain rule combined with the power rule. To do so, we ...
The chain rule can be generalised to multivariate functions, and represented by a tree diagram. The chain rule is applied extensively by the backpropagation algorithm in order to calculate the error gradient of the loss function with respect to each weight. Let’s get started. The Chain Rule ...
The chain rule is used whenever a function has two or more operations being done to its input. That is to say whenever given a composition of functions, the chain rule can be used to differentiate. What is chain rule explain with example? The chain rule states that the derivative of f(...
For the function f(x,y) wherexandyare functions of variablet, we firstdifferentiatethe function partially with respect to one variable and then that variable is differentiated with respect tot. The chain rule is written as: Example Let’s take a look at an example that shows how the chain ...
