A Scaled Gradient Descent Method for Unconstrained …

Eisosome - Wikipedia

WebThe gradient descent method, also known as the method of steepest descent, is an iterative method for unconstrained optimization that takes an initial point x 0and attempts to sequence converging to the minimum of a function f(x) by moving in the direction of the negative gradient (r f(x)). A level surface, or isosurface, is the set of all points where some function has a given value. If f is differentiable, then the dot product (∇f )x ⋅ v of the gradient at a point x with a vector v gives the directional derivative of f at x in the direction v. It follows that in this case the gradient of f is orthogonal to the level sets of f. For example, a level surface in three-dimensional space is defined by an equation of the form F(x, y, z) = c. The gradient of F is then normal to the surface. byd car reviewsWebChanged absOptimiazation.NumberOfVariable from propety to function in ver1.9.0.
