The learner starts with a default model (mean or mode) as a first prediction model. In each iteration it learns a new base model and applies it to the example set. Then, the residuals of the labels are calculated and the next base model is learned. The learned meta model predicts the label by adding all base model predictions.</p><P><P><DL><DT><B>Version:</B></DT> <DD>$Id: AdditiveRegression.java,v 1.8 2008/05/09 19:22:48 ingomierswa Exp $</DD><DT><B>Author:</B></DT> <DD>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/learner/meta/AdditiveRegression.html#PARAMETER_ITERATIONS">PARAMETER_ITERATIONS</A></B></CODE><BR> The parameter name for "The number of iterations.</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/learner/meta/AdditiveRegression.html#PARAMETER_SHRINKAGE">PARAMETER_SHRINKAGE</A></B></CODE><BR> The parameter name for "Reducing this learning rate prevent overfitting but increases the learning time.</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/learner/meta/AdditiveRegression.html#AdditiveRegression(com.rapidminer.operator.OperatorDescription)">AdditiveRegression</A></B>(<A HREF="../../../../../com/rapidminer/operator/OperatorDescription.html" title="class in com.rapidminer.operator">OperatorDescription</A> description)</CODE>⌨️ 快捷键说明
