Syntax
[K,p_max,r]=ImprovedFastGaussTransformChooseParameters(d,h,epsilon,Klimit)
Description
Choose the parameters for the Improved Fast Gauss Transform.
C++ Implementation.
Loads ImprovedFastGaussTransformChooseParameters.dll
Implementation based on:
Fast computation of sums of Gaussians in high dimensions. Vikas C. Raykar, C. Yang, R. Duraiswami, and N. Gumerov, CS-TR-4767, Department of computer science, University of Maryland, Collegepark.
Input
- d...dimension of the points.
- h... the source bandwidth.
- epsilon...the desired error.
- Klimit ...upper limit on the number of clusters, Klimit.
Note : [ Use roughly Klimit=round(40*sqrt(d)/h) ]
Ouput
- K...number of clusters.
- p_max...maximum truncation number for the Taylor series.
- r...source cutoff radius.
