Using the training samples, the weightsmultiplying each of the gaussian basis functions arecalculated using thepseudo-inverse (yielding the minimum least-squares solution). The resultingnetwork is then used to approximate the function between the given "sample"points. </P><H3>Credits</H3><P>This Java applet (?? 快捷鍵說明
