		      *** RELEASE NOTES ***


	File:              README.TXT
	
	Product:           Neural Connection
	
	Version:           1.0


			*** SUMMARY ***

This README file applies to release 1.0 of Neural Connection 
for MS Windows 3.1x.

Neural Connection contains modules for data access, pre-processing and 
display, together with three network models, the Multi-Layer Perceptron,
the Radial Basis function and the Kohonen Network, and three 
linear models, the Closest Class Mean Classifier, Regression and
Principal Component Analysis.

It also contains modules designed for the analysis of time varying data. 
In this release, the modules include a time series window for 
single or multi-step forecasting and a time series plot for displaying
the results in a visual format.
 
											
		*** SUPPLIED DATASETS ***

This release contains a simple NetAgent Script, called NET.AGT which
will load a general problem and guide you through the steps to 
building a topology.


		*** KNOWN PROBLEMS ***

1.  Weight variables in SPSS .SAV files are not supported.

2.  Split variables in SPSS .SAV files are not supported.

3.  Frequency variables in SPSS .SAV files are not supported.

4.  Date type variables in SPSS .SAV files are not fully supported.

5.  When pasting large amounts of data into Neural Connection
    some values may be displayed in the Spreadsheet as having the
    value zero. By paging down a couple of pages and back up again
    the correct values are displayed.
    
6.  Neural Connection only supports version 5.0 Excel files,
    versions 2.1, 3.0 and 4.0 are not supported.
    
7.  When reading a SPSS .SAV file that has become corrupt or is
    invalid the following system message will appear : ZC/BI/xx,
    where xx is a two character code.
    
8.  All case elements which are missing are replaced with the mean
    average for that column and do not appear in the Invalid entries
    list.
    
9.  Files containing large values ( > 1.0E12 ) may cause a floating
    point application error in Neural Connection.
    
10. It is possible in Neural Connection to set field names to SPSS
    reserved words. This is inadvisable if you wish to use the 
    output from Neural Connection in SPSS.

11. Neural Connection does not support Windows NT 3.xx. It will run
    and perform most of the functionality but some of the dialogs
    for various tools are not operational.

12. If the automatic execution of the agent script file, when executing
    neural connection from SPSS, is required to be removed, a new
    file called "SPSS.AGT" must be created to replace the existing one.
    This file should at the very least, initialise a spreadsheet so that
    the data from SPSS can be loaded.
    
13. In handling the missing values in SPSS data (.sav) file, 
    Neural Connection now replaces both user defined missing and 
    system missing values with the mean of valid cases in that 
    variable. Similarly, in handling record delimited data (.csv
    or .txt) file and  field count data (.nna) file, Neural 
    Connection now replaces any missing value with the mean of 
    valid cases in that variable. 

14. Specifying the dimension of Kohonen Layer to either less than 
    1 or greater than 2 in the Kohoen Network tool dialog may 
    cause system errors.

15. Specifying the parameter of Guassion function in the Radial 
    Basis Function layer to 0 in the Radial Basis Function tool 
    dialog may cause mathematical violation error message.  

16. When Principal Component tool is used, it is assumed that all 
    variables are continuous. For categorical (i.e., symbolic) 
    variable, a number of dummy variables such that each of which 
    corresponds to a level of the variable will be created and 
    used as continuous variables. To avoid using categorical 
    variable in the Principal Component tool, use a Filter tool 
    to unselect the categorical variable (if any) before using 
    the Principal Component tool.   

17. If the data set is too big that the text output tool fails
    to write the output on screen, please uncheck  the "Output 
    to Screen" button and check the "Output to File" button in 
    the Format of Dialog of the Text Output tool. User can obtain 
    the full output via the file you specified in the "Output 
    to File" square button. 

18. Simulator tool is supposed to be used for continuous 
    variable. Choosing categorical (i.e., symbolic) variable 
    may cause system error. 

19. Neural Connection may fail to save file in a disk which 
    does not have enough space. User may not be warned by any 
    messsage. 

20. It is known that the Alt-Tab for switching between Windows 
    Applications does not work in the current version of Neural 
    Connection.
