Hi SVMlight by Thorsten Joachims http://www-ai.cs.uni-dortmund.de/SOFTWARE/SVM_LIGHT/svm_light.eng.html optionally incorporating The PR_LOQO optimizer by Alex Smola http://spigot.anu.edu.au/~smola/ mySVM by Stefan Rüping http://www-ai.cs.uni-dortmund.de/SOFTWARE/MYSVM/ I've ported the above two programs so that they now run under Windows 98/NT [1]. They compile under Microsoft Visual C++ 6.0. I've zipped them up and put them here: http://www.cs.ucl.ac.uk/staff/M.Sewell/svm/ Cheers Martin PS Total number of users subscribed to this list: 134 [1] In an MS-DOS Window anyway... <g>
