C# 클래스 Encog.Neural.Networks.Training.PNN.DeriveMinimum

This class determines optimal values for multiple sigmas in a PNN kernel. This is done using a CJ (conjugate gradient) method. Some of the algorithms in this class are based on C++ code from: Advanced Algorithms for Neural Networks: A C++ Sourcebook by Timothy Masters John Wiley Sons Inc (Computers); April 3, 1995 ISBN: 0471105880
