Please note that this operator will also use special attributes which makes it necessary for all preprocessing steps which should be performed on special attributes (and are normally not performed on special attributes).</p> <p>This operator is also able to deliver the additional results of the inner operator if desired.</p> <p>Afterwards, the remaining original attributes are added to the resulting example set if the parameter "keep_subset_only" is set to false (default).</p> <p>Please note that this operator is very powerful and can be used to create new preprocessing schemes by combinating it with other preprocessing operators. Hoewever, there are two major restrictions (among some others): first, since the inner result will be combined with the rest of the input example set, the number of examples (data points) is not allowed to be changed inside of the subset preprocessing. Second, attribute role changes will not be delivered to the outside since internally all special attributes will be changed to regular for the inner operators and role changes can afterwards not be delivered.</p><P><P><DL><DT><B>Version:</B></DT> <DD>$Id: AttributeSubsetPreprocessing.java,v 1.14 2008/07/11 09:42:40 ingomierswa Exp $</DD><DT><B>Author:</B></DT> <DD>Ingo Mierswa, Shevek</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/preprocessing/AttributeSubsetPreprocessing.html#PARAMETER_ATTRIBUTE_NAME_REGEX">PARAMETER_ATTRIBUTE_NAME_REGEX</A></B></CODE><BR> The parameter name for "A regular expression which matches against all attribute names (including special attributes).</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/preprocessing/AttributeSubsetPreprocessing.html#PARAMETER_DELIVER_INNER_RESULTS">PARAMETER_DELIVER_INNER_RESULTS</A></B></CODE><BR> The parameter name for "Indicates if the additional results (other than example set) of the inner operator should also be returned.</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/preprocessing/AttributeSubsetPreprocessing.html#PARAMETER_INVERT_SELECTION">PARAMETER_INVERT_SELECTION</A></B></CODE><BR> The parameter name for "Indicates if the attributes which did not match the regular expression should be removed by this operator.</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/preprocessing/AttributeSubsetPreprocessing.html#PARAMETER_KEEP_SUBSET_ONLY">PARAMETER_KEEP_SUBSET_ONLY</A></B></CODE><BR> The parameter name for "Indicates if the attributes which did not match the regular expression should be removed by this operator.</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/preprocessing/AttributeSubsetPreprocessing.html#PARAMETER_PROCESS_SPECIAL_ATTRIBUTES">PARAMETER_PROCESS_SPECIAL_ATTRIBUTES</A></B></CODE><BR> The parameter name for "Indicates if special attributes like labels etc. should also be processed.</TD></TR></TABLE> <!-- ======== 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/AttributeSubsetPreprocessing.html#AttributeSubsetPreprocessing(com.rapidminer.operator.OperatorDescription)">AttributeSubsetPreprocessing</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 =========== -->⌨️ 快捷键说明
