VRML interface now works with Cosmo Player Beta 3a, and the demo uses a window embedded in the Web page. May 97 Downloading, parsing, and opening new windows are now faster. A new class sim.funApp.Net creates neural networks with any number of layers, each of which implements radial basis functions, sigmoids, linear functions. It also knows how to calculate its own second derivatives. This obsoletes the old sim.funApp.MLP and sim.funApp.Linear.
Menus are now in embedded windows, appearing as pulldown choice lists.
When that file is loaded in, everything picks up where it left off. JAR files are now being used, which work with the Netscape beta. A new class, sim.errFun.Batch, now allows pseudo epochwise batch training on infinite training sets by averaging together N evaluations of an error function. A new class sim.errFun.errAvg now allows several error functions to be combined so that gradient descent on their average is actually performed. Some bugs are fixed, and the majority of the native code for MatrixD and MatrixF is working.
