For non-linear sampling methods, i.e. the data is shuffled, the specified amounts of data are used as training and test set. The sum of both must be smaller than the input example set size. <br/> At least either the training set size must be specified (rest is used for testing) or the test set size must be specified (rest is used for training). If both are specified, the rest is not used at all. The first inner operator must accept an <A HREF="../../../../com/rapidminer/example/ExampleSet.html" title="interface in com.rapidminer.example"><CODE>ExampleSet</CODE></A> while the second must accept an <A HREF="../../../../com/rapidminer/example/ExampleSet.html" title="interface in com.rapidminer.example"><CODE>ExampleSet</CODE></A> and the output of the first (which in most cases is a <A HREF="../../../../com/rapidminer/operator/Model.html" title="interface in com.rapidminer.operator"><CODE>Model</CODE></A>) and must produce a <A HREF="../../../../com/rapidminer/operator/performance/PerformanceVector.html" title="class in com.rapidminer.operator.performance"><CODE>PerformanceVector</CODE></A>.<P><P><DL><DT><B>Version:</B></DT> <DD>$Id: FixedSplitValidationChain.java,v 1.18 2006/04/12 18:04:24 ingomierswa Exp $</DD><DT><B>Author:</B></DT> <DD>Simon Fischer, Ingo Mierswa</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/validation/FixedSplitValidationChain.html#PARAMETER_LOCAL_RANDOM_SEED">PARAMETER_LOCAL_RANDOM_SEED</A></B></CODE><BR> </TD></TR>⌨️ 快捷键说明
