| Also, we consider the concept of general differentiability for fuzzy functions and we plot the h-curve to illustrate the region of convergence in different levels. |
| The sigmoid function is the most commonly used transfer function because of its differentiability. |
| Given the differentiability assumption, it is sufficient to show that the mixed partial derivatives between the choice of gift and parameters are weakly positive. |
| The book then returns to foundations with chapters on contiguity and L2 differentiability. |
| The conical differentiability of solutions with respect to the boundary variations is exploited. |
| The cubic spline interpolation procedure uses parts of third degree polynomials that are linked to the grid points by suitable conditions in such a way that continuous differentiability of the yield curve is ensured. |
