However, a small to medium site that does not require daily analysis will find WizWhy to be an excellent tool for generating rules with probability rates, record counts, and significance measurements. Note also that it has the ability to generate IF/THEN as well as IF/THEN NOT rules, and is able to tell you the probability of the rules and the number of instances as they appear on your training data set.</FONT></TD><TD></TD></TR><TR> <TD COLSPAN=3></TD></TR><TR> <TD COLSPAN=3 HEIGHT=1></TD></TR></TABLE><A NAME='{5F9}'/><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>An important point to consider in the evaluation and selection of data mining tools is that these products and their results can be linked in order to obtain a hybrid solution. For example, you may want to use a decision-tree tool like KnowledgeSEEKER or WizWhy to segment and identify the key variables in your data set, especially if you are dealing with a large number of data fields. Then using the more compressed data set, with a reduced number of variables, you can use a neural network tool like NGO for classification—which with its embedded genetic algorithm can further optimize the accuracy of the final models for your website.
