It presents the data in a spreadsheet format, which after a model is created adds a column with the predicted results. Changes to the data can be made in the spreadsheet environment, so that a graph can easily be created. 4Thought can import fixed and delimited ASCII, Excel, Lotus, and SPSS formats. It is also ODBC compliant and can link to Excel, Btrieve, dBase, and XDB. An ample number of functions are provided for data transformation, which is especially good since it is a neural network tool. It has a wizard-like feature called Autolog, which applies a logarithm to those columns that have a distribution that looks more like a log-normal distribution than a normal distribution. During the construction of a model, dynamic feedback is provided allowing for the user to see how the training and testing are progressing. Once the model is built, a predicted value column is created in the spreadsheet. If new input values are typed in a blank row at the end of the spreadsheet, a new predicted value is automatically computed. In addition, the neural network weights can be exported as a macro function to Excel, Lotus, and SPSS. Several graphs are available for pre- and post-modeling and the comparison between the inputs and the generated outputs.</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='{5B6}'/></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
