WebNot all functions have an absolute maximum or minimum value on their entire domain. For example, the linear function f (x)=x f (x) = x doesn't have an absolute minimum or maximum (it can be as low or as high as we want). However, some functions do have an absolute extremum on their entire domain.

WebThe way gradient descent manages to find the minima of functions is easiest to imagine in three dimensions. Think of a function f (x, y) f (x,y) that defines some hilly terrain when graphed as a height map. We learned that the gradient evaluated at any point represents the direction of steepest ascent up this hilly terrain.
