WebJul 19, 2024 · A multivariate function depends on several input variables to produce an output. The gradient of a multivariate function is computed by finding the derivative of the function in different directions. Multivariate calculus is used extensively in neural networks to update the model parameters. Let’s get started. WebOnce the partial derivatives are found here, we have a system of two equations to solve: $$\left\{\begin{aligned} y&=-x^2,\\ y^2&=x. \end{aligned}\right.$$ The reason for setting it up is the definition of stationary points.
