Web29 jun. 2024 · Well, a cost function is something we want to minimize. For example, our cost function might be the sum of squared errors over the training set. Gradient descent is a method for finding the minimum of a function of multiple variables. So we can use gradient descent as a tool to minimize our cost function. WebFinally, the cost functional can b e rewritten as: J = Z 1 0 ^ L ( ^ x; u) ds and the task is to minimize J in extended state space.

WebScore: 5/5 (4 votes) . When we talk of maximizing or minimizing a function what we mean is what can be the maximum possible value of that function or the minimum possible value of that function.This can be defined in terms of global range or local range. WebMaxima and minima in calculus are found by using the concept of derivatives. As we know the concept the derivatives gives us the information regarding the gradient/ slope of the function, we locate the points where the gradient is zero and these points are called turning points/stationary points.
