Just as physical retailers are using these data mining technologies to assist them in the design of their stores and the management of their inventory, so can web teams use GAs and nets to assist them in mining for the most effective website design for e-commerce. For example, what banners or offers and incentives should be paired up for each of your various product lines? What is the most revenue-effective sequence to arrange your pages? Which offers tend to maximize clickthroughs or ad views, or what product combinations tend to be optimized for improved sales?</FONT></TD><TD></TD></TR><TR> <TD COLSPAN=3></TD></TR><TR> <TD COLSPAN=3 HEIGHT=1></TD></TR></TABLE><A NAME='{AFA}'/><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>As we have said from the beginning of the book, data mining technology is about perception and learning, which is what neural networks and genetic algorithms are designed to emulate. This evolutionary type of computing technologies can assist the designer and administrator of a website in optimizing their virtual storefront to ensure they are getting their biggest bang for their buck. Through the use of these data mining tools you can leverage the pattern recognition capabilities of the network to maximize your marketing and retailing efforts on the Web, with the GA being used to optimize the effectiveness of the network.</FONT><FONT FACE='Times New Roman, Times, Serif' SIZE=3 COLOR=#FFFF00><!-- break --></FONT></TD><TD></TD></TR><TR> <TD COLSPAN=3></TD></TR><TR> <TD COLSPAN=3 HEIGHT=1></TD></TR></TABLE><A NAME='{AFB}'/></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
