Problem decomposition is performed in an error-driven manner, such that the resulting subtasks (patches) are equally well approximated. Our method combines an unsupervised learning scheme (Feature Maps [Koh84]) with a nonlinear approximator (Backpropagation [RHW86]). The resulting learning system is more stable and effective in changing environments than plain backpropagation and much more powerful than extended feature maps as proposed by [RMW89]. Extensions of our method give rise to active exploration strategies for autonomous agents facing unknown environments. The appropriateness of this technique is demonstrated with an example from mathematical function approximation. - ----------------------------------------------------------------------------- To obtain copies of the postscript file, please use Jordan Pollack's service: Example: unix> ftp cheops.cis.ohio-state.edu # (or ftp 128.146.8.62) Name (cheops.cis.ohio-state.edu:): anonymous Password (cheops.cis.ohio-state.edu:anonymous): <ret> ftp> cd pub/neuroprose ftp> binary ftp> get (remote-file) fox.decomp.ps.Z (local-file) fox.decomp.ps.Z ftp> quit unix> uncompress fox.decomp.ps.Z unix> lpr -P((your_local_postscript_printer) fox.decomp.ps.Z - ---------------------------------------------------------------------------- If you have any difficulties with the above, please send e-mail to moeller@kiti.informatik.uni-bonn.de DO NOT "reply" to this message!! ------- End of Forwarded Message -- comp.archives file verification cheops.cis.ohio-state.edu -rw-r--r-- 1 3169 274 745782 Jun 10 10:10 /pub/neuroprose/fox.decomp.ps.Z found fox-decomp ok cheops.cis.ohio-state.edu:/pub/neuroprose/fox.decomp.*
