Summary

0000430: IMPLEMENTED: RBF model

Description

RBF model for interpolation in 2 and 3-dimensional spaces, which:
* supports Gaussian RBF's with additional linear term
* supports scattered interpolation with two algorithms:
** RBF-QNN - suited for approximately uniformly distributed points, perfect fit
** RBF-ML - multilayer RBF model which is able to fit any distribution of points, and can solve problems in the least squares sense (imperfect fit) with controllable amount of smoothing
* supports interpolation of scalar and vector functions
* can calculate function values at arbitrary points and on regular grids
* supports serialization
* uses efficient O(N*logN) algorithms to build model, suited for interpolation of very large datasets (100000 points and even more)
