In our sample data set of 1472 observations with seven fields as inputs/outputs, the NGO ran for over six hours before it converged on an answer. This process is clearly computationally intensive, but the effectiveness of genetic algorithms combinatorial search capabilities with neural networks is truly great. During a run, the NGO provides you the ability to view the status of what is happening, view the evolving population, see the configurations and the statistics of the top ten networks. You can also observe learning curves and watch the neural outputs match your desired data for the network being trained and view and/or print reports on the specifics of the system setup and the resulting top networks. After several hours NGO found that being from a ZIP code with a high percentage of "Successful Suburbanite" consumer class was the most important attribute for predicting online sales.</FONT></TD><TD></TD></TR><TR> <TD COLSPAN=3></TD></TR><TR> <TD COLSPAN=3 HEIGHT=1></TD></TR></TABLE><A NAME='{5ED}'/><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><B><I>WizWhy</I></B></FONT></TD><TD></TD></TR><TR> <TD COLSPAN=3></TD></TR><TR> <TD COLSPAN=3 HEIGHT=1></TD></TR></TABLE><A NAME='{5EE}'/><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>WizWhy is a data mining tool originally developed and marketed in Israel. It uses a proprietary algorithm to generate IF/THEN rules and predictions. This algorithm is very extensive, meaning that the more data samples you have the longer it takes to generate rules. Another minor concern about WizWhy is that it generates a very large number of rules, which luckily, the user is able to reduce at the end of the data mining analysis. The interface is fairly straightforward, prompting you</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='{5EF}'/><TABLE CELLPADDING=0 CELLSPACING=0 BORDER=0 WIDTH='100%'><TR><TD HEIGHT=12></TD></TR><TR><TD><TABLE CELLSPACING=0 BGCOLOR=#C0C0C0 BORDER=1 BORDERCOLOR=#000000 WIDTH=626 CELLPADDING=5><TR><TD WIDTH=626 VALIGN=TOP><TABLE BORDER=0 CELLSPACING=0 CELLPADDING=0 WIDTH='100%'><TR><TD ALIGN=CENTER><FONT FACE='Times New Roman, Times, Serif' SIZE=2><B>WizWhy</B></FONT></TD></TR></TABLE></TD></TR><TR><TD WIDTH=626 VALIGN=TOP><FONT FACE='Times New Roman, Times, Serif' SIZE=2><B>Best at:</B> Classification</FONT></TD></TR><TR><TD WIDTH=626 VALIGN=TOP><FONT FACE='Times New Roman, Times, Serif' SIZE=2><B>Cost Factor:</B> Yes</FONT></TD></TR><TR><TD WIDTH=626 VALIGN=TOP><FONT FACE='Times New Roman, Times, Serif' SIZE=2><B>Current Version:</B> 1.1</FONT></TD></TR><TR><TD WIDTH=626 VALIGN=TOP><FONT FACE='Times New Roman, Times, Serif' SIZE=2><B>Data Access:</B> ASCII/dBASE</FONT></TD></TR><TR><TD WIDTH=626 VALIGN=TOP><FONT FACE='Times New Roman, Times, Serif' SIZE=2><B>Data Preprocessing:</B> None</FONT></TD></TR><TR><TD WIDTH=626 VALIGN=TOP><FONT FACE='Times New Roman, Times, Serif' SIZE=2><B>Distinguishing Feature:</B> Provides rule probability, count, and significance level</FONT></TD></TR><TR><TD WIDTH=626 VALIGN=TOP><FONT FACE='Times New Roman, Times, Serif' SIZE=2><B>File Limitations:</B> None</FONT></TD></TR><TR><TD WIDTH=626 VALIGN=TOP><FONT FACE='Times New Roman, Times, Serif' SIZE=2><B>Installed Base:</B> 100</FONT></TD></TR><TR><TD WIDTH=626 VALIGN=TOP><FONT FACE='Times New Roman, Times, Serif' SIZE=2><B>Memory Required:</B> 640 K</FONT></TD></TR><TR><TD WIDTH=626 VALIGN=TOP><FONT FACE='Times New Roman, Times, Serif' SIZE=2><B>Parallel Processing Support:</B> No</FONT></TD></TR><TR><TD WIDTH=626 VALIGN=TOP><FONT FACE='Times New Roman, Times, Serif' SIZE=2><B>Pricing:</B> $5,000</FONT></TD></TR><TR><TD WIDTH=626 VALIGN=TOP><FONT FACE='Times New Roman, Times, Serif' SIZE=2><B>Solution Format:</B> IF/THEN rules</FONT></TD></TR><TR><TD WIDTH=626 VALIGN=TOP><FONT FACE='Times New Roman, Times, Serif' SIZE=2><B>Space Required:</B> 1.5 MB</FONT></TD></TR><TR><TD WIDTH=626 VALIGN=TOP><FONT FACE='Times New Roman, Times, Serif' SIZE=2><B>Training/Consulting:</B> Yes</FONT></TD></TR><TR><TD WIDTH=626 VALIGN=TOP><FONT FACE='Times New Roman, Times, Serif' SIZE=2><B>Technology Paradigm:</B> Proprietary Algorithm</FONT></TD></TR></TABLE></TD></TR></TABLE><BR><A NAME='{5F0}'/></FORM></P></TD></TR></TABLE><P><FONT SIZE=0 COLOR=WHITE></CENTER><A NAME="bottom"> </A><!-- netLibrary.com Copyright Notice --> </BODY></HTML>?? 快捷鍵說明
