This program demonstrates some function approximation capabilities of a Radial Basis Function Network. Next, the user specifies the number of equally spaced gaussian centers and the variance for the network.
Instructions Use the first mouse button to place training points in the upper section.
Try to space them approximately equally, and place more points than number of centers being used. After any adjustment to the number of centers or variance, click on this button to show the new basis functions. Status messages are shown at the bottom of the applet. Comments After learning, the scaled plots of each of the gaussians is shown in green in the upper graph. The resulting approximation of the curve which is the sum of all the scaled gaussians is shown in red.
