(附件中含源代码) Schoenberg (1964) showed if n≥m, the minimizer is unique and he called it natural polynomial spline. Statisticians were interested in smoothing the spline other than interpolating since the existence of noise. In Practice , especially for applications in Image Registration ...
Gradient descent method Search line : gradient direction The minimization in the search line must be tangent to the contour of f(x). Problem: convergence is slow in most situations So, using conjugate direction, for 2-dimension space, we can find the minimization in 2 steps: Find an ...
