Adaptive Fusion of Kernels for Radial Basis Function Neural Network

Simulation of adaptive fusion of two kernels of RBF for pattern recognition example

In this algorithm the two popular similarity measures, Cosine distance (angle) and Euclidean distance are fused together and the mixing weight is made adaptive using gradient decent algorithm. The submission is the example for pattern recognition problem utilized in the paper [1].
