Hence, this operator works very similar to the well know transpose operation for matrices.</p> <p>If an Id attribute is part of the given example set, the ids will become the names of the new attributes. The names of the old attributes will be transformed into the id values of a new special Id attribute. Since no other "special" examples or data rows exist, all other new attributes will be regular after the transformation. You can use the <A HREF="../../../../com/rapidminer/operator/preprocessing/filter/ChangeAttributeType.html" title="class in com.rapidminer.operator.preprocessing.filter"><CODE>ChangeAttributeType</CODE></A> operator in order to change one of these into a special type afterwards.</p> <p>If all old attribute have the same value type, all new attributes will have this value type. Otherwise, the new value types will all be "nominal" if at least one nominal attribute was part of the given example set and "real" if the types contained mixed numbers.</p> <p>This operator produces a copy of the data in the main memory and it therefore not suggested to use it on very large data sets.</p><P><P><DL><DT><B>Version:</B></DT> <DD>$Id: ExampleSetTranspose.java,v 1.5 2008/07/07 07:06:42 ingomierswa Exp $</DD><DT><B>Author:</B></DT> <DD>Ingo Mierswa</DD></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/preprocessing/ExampleSetTranspose.html#ExampleSetTranspose(com.rapidminer.operator.OperatorDescription)">ExampleSetTranspose</A></B>(<A HREF="../../../../com/rapidminer/operator/OperatorDescription.html" title="class in com.rapidminer.operator">OperatorDescription</A> description)</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> <A HREF="../../../../com/rapidminer/operator/IOObject.html" title="interface in com.rapidminer.operator">IOObject</A>[]</CODE></FONT></TD><TD><CODE><B><A HREF="../../../../com/rapidminer/operator/preprocessing/ExampleSetTranspose.html#apply()">apply</A></B>()</CODE><BR> Implement this method in subclasses.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> java.lang.Class<?>[]</CODE></FONT></TD><TD><CODE><B><A HREF="../../../../com/rapidminer/operator/preprocessing/ExampleSetTranspose.html#getInputClasses()">getInputClasses</A></B>()</CODE><BR> Returns the classes that are needed as input.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> java.lang.Class<?>[]</CODE></FONT></TD><TD><CODE><B><A HREF="../../../../com/rapidminer/operator/preprocessing/ExampleSetTranspose.html#getOutputClasses()">getOutputClasses</A></B>()</CODE><BR> Returns the classes that are guaranteed to be returned by <tt>apply()</tt> as additional output.</TD></TR></TABLE>⌨️ 快捷键说明
