colinear attributes.</li> <li>Set the XProperty to "filter.numComponents", XMin to "5", XMax to "20" (this depends heavily on your dataset, should be no more than the number of attributes!), XStep to "1" and XExpression to "I". This will test the number of components the PLSFilter will produce from 5 to 20.</li> <li>Set the YProperty to "classifier.ridge", XMin to "-10", XMax to "5", YStep to "1" and YExpression to "pow(BASE,I)". This will try ridge parameters from 10^-10 to 10^5.</li> </ul> </li> </ul> General notes: <ul> <li>Turn the <i>debug</i> flag on in order to see some progress output in the console</li> <li>If you want to view the fitness landscape that GridSearch explores, select a <i>log file</i>. This log will then contain Gnuplot data and script block for viewing the landscape. Just copy paste those blocks into files named accordingly and run Gnuplot with them.</li> </ul><P><P><DL><DT><B>Version:</B></DT> <DD>$Revision: 1.3 $</DD><DT><B>Author:</B></DT> <DD>Bernhard
