The example set <i>S</i> is split up into <var> number_of_validations</var> subsets <i>S_i</i>. The inner operators are applied <var>number_of_validations</var> times using <i>S_i</i> as the test set (input of the second inner operator) and <i>S\backslash S_i</i> training set (input of the first inner operator). </p> <p>In contrast to the usual cross validation operator (see <A HREF="../../../../com/rapidminer/operator/validation/XValidation.html" title="class in com.rapidminer.operator.validation"><CODE>XValidation</CODE></A>) this operator does not (randomly) split the data itself but uses the partition defined by the special attribute "batch". This can be an arbitrary nominal or integer attribute where each possible value occurs at least once (since many learning schemes depend on this minimum number of examples). </p> <p> 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 is in most cases 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><P><DL><DT><B>Version:</B></DT> <DD>$Id: BatchXValidation.java,v 1.7 2008/06/06 09:37:14 ingomierswa Exp $</DD><DT><B>Author:</B></DT>⌨️ 快捷键说明
