the cascade network seems to be having the same problems it was having two summers ago, seeming to try to match all the training points but generally just getting it all wrong. i added a few status message updates to the program, so you can see how it is doing as it is training. the file cascnet6.nb is backed up on euclid. here is an image of the networks output after training with a circle pattern (i ended it before it got to the minimum error).
