In contrast to the normal forward selection this one actually selects attributes instead of completely adding them. Although this might use more memory for simple selection tasks this might be necessary in case of FeatureOperators which generate new attributes.<P><P><DL><DT><B>Version:</B></DT> <DD>$Id: SwitchingForwardSelection.java,v 1.1 2006/04/14 11:42:27 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/features/selection/SwitchingForwardSelection.html#SwitchingForwardSelection()">SwitchingForwardSelection</A></B>()</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> java.util.List<<A HREF="../../../../../com/rapidminer/operator/features/Individual.html" title="class in com.rapidminer.operator.features">Individual</A>></CODE></FONT></TD><TD><CODE><B><A HREF="../../../../../com/rapidminer/operator/features/selection/SwitchingForwardSelection.html#operate(com.rapidminer.operator.features.Individual)">operate</A></B>(<A HREF="../../../../../com/rapidminer/operator/features/Individual.html" title="class in com.rapidminer.operator.features">Individual</A> individual)</CODE><BR> Subclasses must implement this method providing a list of new individuals.</TD></TR></TABLE> <A NAME="methods_inherited_from_class_com.rapidminer.operator.features.IndividualOperator"><!-- --></A><TABLE BORDER="1" WIDTH="100%" CELLPADDING="3" CELLSPACING="0" SUMMARY=""><TR BGCOLOR="#EEEEFF" CLASS="TableSubHeadingColor"><TH ALIGN="left"><B>Methods inherited from class com.rapidminer.operator.features.<A HREF="../../../../../com/rapidminer/operator/features/IndividualOperator.html" title="class in com.rapidminer.operator.features">IndividualOperator</A></B></TH></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD><CODE><A HREF="../../../../../com/rapidminer/operator/features/IndividualOperator.html#operate(com.rapidminer.operator.features.Population)">operate</A>, <A HREF="../../../../../com/rapidminer/operator/features/IndividualOperator.html#performOperation(int)">performOperation</A></CODE></TD></TR></TABLE> <A NAME="methods_inherited_from_class_java.lang.Object"><!-- --></A><TABLE BORDER="1" WIDTH="100%" CELLPADDING="3" CELLSPACING="0" SUMMARY=""><TR BGCOLOR="#EEEEFF" CLASS="TableSubHeadingColor"><TH ALIGN="left"><B>Methods inherited from class java.lang.Object</B></TH></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD><CODE>clone, equals, finalize, getClass, hashCode, notify, notifyAll, toString, wait, wait, wait</CODE></TD></TR></TABLE> <P><!-- ========= CONSTRUCTOR DETAIL ======== --><A NAME="constructor_detail"><!-- --></A><TABLE BORDER="1" WIDTH="100%" CELLPADDING="3" CELLSPACING="0" SUMMARY=""><TR BGCOLOR="#CCCCFF" CLASS="TableHeadingColor"><TH ALIGN="left" COLSPAN="1"><FONT SIZE="+2"><B>Constructor Detail</B></FONT></TH></TR></TABLE><A NAME="SwitchingForwardSelection()"><!-- --></A><H3>SwitchingForwardSelection</H3><PRE>public <B>SwitchingForwardSelection</B>()</PRE><DL></DL><!-- ============ METHOD DETAIL ========== --><A NAME="method_detail"><!-- --></A><TABLE BORDER="1" WIDTH="100%" CELLPADDING="3" CELLSPACING="0" SUMMARY=""><TR BGCOLOR="#CCCCFF" CLASS="TableHeadingColor"><TH ALIGN="left" COLSPAN="1"><FONT SIZE="+2"><B>Method Detail</B></FONT></TH></TR></TABLE><A NAME="operate(com.rapidminer.operator.features.Individual)"><!-- --></A><H3>operate</H3><PRE>public java.util.List<<A HREF="../../../../../com/rapidminer/operator/features/Individual.html" title="class in com.rapidminer.operator.features">Individual</A>> <B>operate</B>(<A HREF="../../../../../com/rapidminer/operator/features/Individual.html" title="class in com.rapidminer.operator.features">Individual</A> individual)</PRE><DL><DD><B>Description copied from class: <CODE><A HREF="../../../../../com/rapidminer/operator/features/IndividualOperator.html#operate(com.rapidminer.operator.features.Individual)">IndividualOperator</A></CODE></B></DD><DD>Subclasses must implement this method providing a list of new individuals. <tt>individual</tt> will be removed from the population so it might be useful to return a list of size 1 containing only the modified <tt>individual</tt>.
