The SVM is a powerful method for both classification and regression. This operator supports the SVM types <code>C-SVC</code> and <code>nu-SVC</code> for classification tasks and <code>epsilon-SVR</code> and <code>nu-SVR</code> for regression tasks. Supports also multiclass learning and probability estimation based on Platt scaling for proper confidence values after applying the learned model on a classification data set.<P><P><DL><DT><B>Version:</B></DT> <DD>$Id: LibSVMLearner.java,v 1.13 2008/05/09 19:23:01 ingomierswa Exp $</DD><DT><B>Author:</B></DT> <DD>Ingo Mierswa</DD><DT><B>Keywords:</B></DT> <DD>SVM</DD></DL><HR><P><!-- =========== FIELD SUMMARY =========== --><A NAME="field_summary"><!-- --></A><TABLE BORDER="1" WIDTH="100%" CELLPADDING="3" CELLSPACING="0" SUMMARY=""><TR BGCOLOR="#CCCCFF" CLASS="TableHeadingColor"><TH ALIGN="left" COLSPAN="2"><FONT SIZE="+2"><B>Field Summary</B></FONT></TH></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE>static java.lang.String[]</CODE></FONT></TD><TD><CODE><B><A HREF="../../../../../../com/rapidminer/operator/learner/functions/kernel/LibSVMLearner.html#KERNEL_TYPES">KERNEL_TYPES</A></B></CODE><BR> The different kernel types implemented by the LibSVM package.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE>static java.lang.String</CODE></FONT></TD><TD><CODE><B><A HREF="../../../../../../com/rapidminer/operator/learner/functions/kernel/LibSVMLearner.html#PARAMETER_C">PARAMETER_C</A></B></CODE><BR> The parameter name for "The cost parameter C for c_svc, epsilon_svr, and nu_svr.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE>static java.lang.String</CODE></FONT></TD><TD><CODE><B><A HREF="../../../../../../com/rapidminer/operator/learner/functions/kernel/LibSVMLearner.html#PARAMETER_CACHE_SIZE">PARAMETER_CACHE_SIZE</A></B></CODE><BR> The parameter name for "Cache size in Megabyte.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE>static java.lang.String</CODE></FONT></TD><TD><CODE><B><A HREF="../../../../../../com/rapidminer/operator/learner/functions/kernel/LibSVMLearner.html#PARAMETER_CALCULATE_CONFIDENCES">PARAMETER_CALCULATE_CONFIDENCES</A></B></CODE><BR> The parameter name for "Indicates if proper confidence values should be calculated.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE>static java.lang.String</CODE></FONT></TD><TD><CODE><B><A HREF="../../../../../../com/rapidminer/operator/learner/functions/kernel/LibSVMLearner.html#PARAMETER_CLASS_WEIGHTS">PARAMETER_CLASS_WEIGHTS</A></B></CODE><BR> The parameter name for "The weights w for all classes (first column: class name, second column: weight), i.e. set the parameters C of each class w * C (empty: using 1 for all classes where the weight was not defined).</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE>static java.lang.String</CODE></FONT></TD><TD><CODE><B><A HREF="../../../../../../com/rapidminer/operator/learner/functions/kernel/LibSVMLearner.html#PARAMETER_COEF0">PARAMETER_COEF0</A></B></CODE><BR> The parameter name for "The parameter coef0 for polynomial and sigmoid kernel functions.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE>static java.lang.String</CODE></FONT></TD><TD><CODE><B><A HREF="../../../../../../com/rapidminer/operator/learner/functions/kernel/LibSVMLearner.html#PARAMETER_CONFIDENCE_FOR_MULTICLASS">PARAMETER_CONFIDENCE_FOR_MULTICLASS</A></B></CODE><BR> The parameter name for "Indicates if proper confidence values should be calculated.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE>static java.lang.String</CODE></FONT></TD><TD><CODE><B><A HREF="../../../../../../com/rapidminer/operator/learner/functions/kernel/LibSVMLearner.html#PARAMETER_DEGREE">PARAMETER_DEGREE</A></B></CODE><BR> The parameter name for "The degree for a polynomial kernel function.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE>static java.lang.String</CODE></FONT></TD><TD><CODE><B><A HREF="../../../../../../com/rapidminer/operator/learner/functions/kernel/LibSVMLearner.html#PARAMETER_EPSILON">PARAMETER_EPSILON</A></B></CODE><BR>⌨️ 快捷键说明
