Since errors should be minimized, the fitness is calculated as -1 multiplied by the the error. Subclasses might also want to implement the method <code>transform(double)</code> which applies a transformation on the value sum divided by the number of counted examples. This is for example usefull in case of root_means_squared error. All subclasses can be used for both regression and classification problems. In case of classification the confidence value for the desired true label is used as prediction.<P><P><DL><DT><B>Version:</B></DT> <DD>$Id: SimpleCriterion.java,v 1.6 2008/05/09 19:22:43 ingomierswa Exp $</DD><DT><B>Author:</B></DT> <DD>Ingo Mierswa, Simon Fischer</DD><DT><B>See Also:</B><DD><A HREF="../../../../serialized-form.html#com.rapidminer.operator.performance.SimpleCriterion">Serialized Form</A></DL><HR><P><!-- ======== CONSTRUCTOR SUMMARY ======== --><A NAME="constructor_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>Constructor Summary</B></FONT></TH></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD><CODE><B><A HREF="../../../../com/rapidminer/operator/performance/SimpleCriterion.html#SimpleCriterion()">SimpleCriterion</A></B>()</CODE><BR> </TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD><CODE><B><A HREF="../../../../com/rapidminer/operator/performance/SimpleCriterion.html#SimpleCriterion(com.rapidminer.operator.performance.SimpleCriterion)">SimpleCriterion</A></B>(<A HREF="../../../../com/rapidminer/operator/performance/SimpleCriterion.html" title="class in com.rapidminer.operator.performance">SimpleCriterion</A> sc)</CODE><BR> </TD></TR></TABLE> <!-- ========== METHOD SUMMARY =========== --><A NAME="method_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>Method Summary</B></FONT></TH></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> void</CODE></FONT></TD><TD><CODE><B><A HREF="../../../../com/rapidminer/operator/performance/SimpleCriterion.html#buildSingleAverage(com.rapidminer.tools.math.Averagable)">buildSingleAverage</A></B>(<A HREF="../../../../com/rapidminer/tools/math/Averagable.html" title="class in com.rapidminer.tools.math">Averagable</A> performance)</CODE><BR> This method should build the average of this and another averagable of the same type.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE>protected abstract double</CODE></FONT></TD><TD><CODE><B><A HREF="../../../../com/rapidminer/operator/performance/SimpleCriterion.html#countExample(double, double)">countExample</A></B>(double label, double predictedLabel)</CODE><BR> Subclasses must count the example and return the value to sum up.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> void</CODE></FONT></TD><TD><CODE><B><A HREF="../../../../com/rapidminer/operator/performance/SimpleCriterion.html#countExample(com.rapidminer.example.Example)">countExample</A></B>(<A HREF="../../../../com/rapidminer/example/Example.html" title="class in com.rapidminer.example">Example</A> example)</CODE><BR> Invokes <code>countExample(double, double)</code> and counts the deviation.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE>protected void</CODE></FONT></TD><TD><CODE><B><A HREF="../../../../com/rapidminer/operator/performance/SimpleCriterion.html#countExampleWithWeight(double, double)">countExampleWithWeight</A></B>(double deviation, double weight)</CODE><BR> </TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> double</CODE></FONT></TD><TD><CODE><B><A HREF="../../../../com/rapidminer/operator/performance/SimpleCriterion.html#getExampleCount()">getExampleCount</A></B>()</CODE><BR> Returns the number of data points which was used to determine the criterion value.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor">⌨️ 快捷键说明
