The Field Operators allow the user to filter records, create record types, and derive fields as well as other preprocessing transformations. A graphical group of nodes allow the user to generate plots, histograms, distribution charts, and generate a link association graph it calls "the web."</FONT></TD><TD></TD></TR><TR> <TD COLSPAN=3></TD></TR><TR> <TD COLSPAN=3 HEIGHT=1></TD></TR></TABLE><A NAME='{611}'/><TABLE BORDER=0 CELLSPACING=0 CELLPADDING=0><TR> <TD ROWSPAN=5></TD> <TD COLSPAN=3 HEIGHT=12></TD> <TD ROWSPAN=5></TD></TR><TR> <TD COLSPAN=3></TD></TR><TR><TD></TD> <TD><FONT FACE='Times New Roman, Times, Serif' SIZE=3>The modeling nodes allow the user to perform several operations including classification, segmentation, and clustering. Classification models can be constructed either via standard regression or a back-propagation neural network. Segmentation can be done via the C5.0 or ID3 machine-learning algorithms. The clustering is done with the Kohonen (SOM) neural network and the standard statistical nearest neighbor method. Several Output nodes are included to explore the results of the modeling processes as well as to generate C code for use by production systems.</FONT></TD><TD></TD></TR><TR> <TD COLSPAN=3></TD></TR><TR> <TD COLSPAN=3 HEIGHT=1></TD></TR></TABLE><A NAME='{612}'/><TABLE BORDER=0 CELLSPACING=0 CELLPADDING=0><TR> <TD ROWSPAN=5></TD> <TD COLSPAN=3 HEIGHT=12></TD> <TD ROWSPAN=5></TD></TR><TR> <TD COLSPAN=3></TD></TR><TR><TD></TD> <TD><FONT FACE='Times New Roman, Times, Serif' SIZE=3>To build a model the user simply selects and links the various Records, Field, Modeling, Graph, and Output nodes. Through this linking process procedures are created labeled "streams" by Clementine. These streams control data preparation, selection, partitioning, model building, testing, evaluation, and deployment. The stream pane is the primary work area, and the palettes across the bottom of the main panel contain the nodes and the "nuggets" that</FONT><FONT FACE='Times New Roman, Times, Serif' SIZE=3 COLOR=#FFFF00><!-- continue --></FONT></TD><TD></TD></TR><TR> <TD COLSPAN=3></TD></TR><TR> <TD COLSPAN=3 HEIGHT=1></TD></TR></TABLE><A NAME='{613}'/></FORM></P></TD></TR></TABLE><P><FONT SIZE=0 COLOR=WHITE></CENTER><A NAME="bottom"> </A><!-- netLibrary.com Copyright Notice --> </BODY></HTML>⌨️ 快捷键说明
