This will include a graphic interface which will support X11, SunView, GL and NextStep. We are able to have such an interface because we are using the libraries of a scientific visualization software package called apE. Users interested in having this graphical interface should get a copy of apE2.1 **NOW** so that when Aspirin/MIGRAINES version 5.0 is released it can be used with the apE software. The apE software is available from the Ohio Supercomputing Center for a nominal charge (I believe it is now free for educational institutions, but I am not sure). Order forms can be ftp'd from "apE.osgp.osc.edu" (128.146.18.18) in the /pub/doc/info directory. The Good News: 1. The apE software is free (or nearly free). 2. The apE software is a very portable package. 3. The apE software supports many window systems. 4. You get source with the apE software. 5. The apE tool called "wrench" allows graphical programmimg, of a sort, by connecting boxes with data pipes. A neural network compute module (which A/M can automatically generate) can be used in these pipelines with other compute/graphics modules for pre/post processing. 6. We can get out of the computer graphics business. 7. Sexy data displays. 8. ApE is a nice visualization package, and the price is right. The Bad News: 1. You need more software than what comes with the Aspirin/MIGRAINES distribution (although, you can run without any graphics with the supplied software). 2. The apE software is not very fast and uses alot of memory. 3. apE2.1 is a big distribution Other features to expect in version 5.0: 1. Support for more platforms: Sun,SGI,DecStation,IBM RS/6000,Cray,Convex,Meiko,i860 based coprocessors,... 2. New features for Aspirin: - Quadratic connections (allows hyper-elliptical decision surfaces) - Auto-Regressive Nodes (allows each node to have an auto-regressive memory, with tunable feedback weights). - New file formats Russell Leighton INTERNET: russ@dash.mitre.org Russell Leighton MITRE Signal Processing Lab 7525 Colshire Dr. McLean, Va. 22102 USA -- comp.archives file verification polaris.cognet.ucla.edu -rw-rw-rw- 1 2018 2001 2111841 Mar 1 15:42 /alexis/am4.tar.Z found asprin-for-migraines ok polaris.cognet.ucla.edu:/alexis/am4.tar.Z
