What is (OS[X])tlearn?
tlearn is a backpropagation neural network simulator, written by Jeff Elman. xtlearn is a version of tlearn for the X Window System. OSXtlearn is xtlearn wrapped in a MacOSX application bundle that runs on MacOSX 10.5 or higher and that requires XQuartz. OSXtlearn is created by Harm Brouwer.
Disclaimer: OSXtlearn is ported "as is". This means that any bugs present in the original (x)tlearn source code might also be present in OSXtlearn.
Known issues: The OSXtlearn application icon keeps bouncing in the dock for a long time. Also, clicking the red close button on any window will terminate OSXtlearn. These issues are both caused by running X applications on MacOSX. I do not intend to fix these issues, and refer you to LensOSX instead.
