Let z = x4e3y. round () is a step function so it has derivative zero almost everywhere. Although it’s differentiable (almost everywhere), it’s not useful for learning because of the zero gradient. clamp () is linear, with slope 1, inside (min, max) and flat outside of the range. This means the derivative is 1 inside (min, max) and zero outside.Definition: Derivative Function. Let f be a function. The derivative function, denoted by f ′, is the function whose domain consists of those values of x such that the following limit exists: f ′ (x) = lim h → 0f(x + h) − f(x) h. A function f(x) is said to be differentiable at a if f ′ (a) exists. Both, holomorphic and analytic functions, are infinitely continuous differentiable. But a differentiable functions is not necessarily infinitely differentiable, moreover: an infinitely differentiable function is not necessarily analytic or holomorphic.
