WebNov 2, 2024 · Normally, a square root function can have critical numbers (and relative extrema) at values of the independent variable where the derivative does not exist and there is a cusp in its graph, i.e., where the original function crosses the \(x\)- or \(t\)-axis and makes the denominator of the derivative function \(0\). WebJun 29, 2024 · Three of the most commonly-used activation functions used in ANNs are the identity function, the logistic sigmoid function, and the hyperbolic tangent function. Examples of these functions and their associated gradients (derivatives in 1D) are plotted in Figure 1.
