Description

Computes and approximation to such that , where .

C++ Implementation.

Loads DataAdaptiveImprovedFastGaussTransform.dll

A new version of the IFGT where the parameters are chosen based on the acutal distribution of the source points. The truncation number for each source point is different and is chosen based on its distance to the cluster center.

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.
