关于自组织神经网络的一种新结构程序,并包含了其它几种神经网络的程序比较

10.03.1997: Version 1.3 released.

These are the most important changes from v1.0 to v1.3:

09.03.1997: Proofred the manual.
08.03.1997: Changed the order of the models (model menu
            and manual).
07.03.1997: GNG: added two variables (alpha, beta).
06.03.1997: Tuned the code (20% faster).
05.03.1997: Cleaned up the code/deleted DEBUG statements.
04.03.1997: Updated the manual.
03.03.1997: Added a new button 'Random Init'.
02.03.1997: Made some improvements concerning LBG.

28.02.1997: Version 1.2 released.
26.02.1997: Version 1.1 skipped for PR reasons :-).

24.02.1997: Added description of the model specific options to
            the manual.
24.02.1997: Improved the variable learning rate for Hard
            Competitive Learning.
21.02.1997: Changed eta to epsilon.
20.02.1997: First draft of the manual for v1.1.
18.02.1997: Updated the manual.
17.02.1997: Made some screendumps for the manual.
30.10.1996: Some improvements and a bugfix concerning the error
            values. 
28.10.1996: New method Self-organizing map (SOM).
23.10.1996: Redesigned the user interface. I have made minor
            changes only. The next major version 2.0 will have
            a complete new interface. 
22.10.1996: Added a close button to the error graph.
21.10.1996: In the method Growing Grid a percentage counter appears
            in the fine-tuning phase. At 100% the calculation stops.
17.10.1996: Added a new button 'White'. It switches the background
            of the drawing area to white. This is useful for making
            hardcopies of the screen.
17.10.1996: New distribution UNIT.
16.10.1996: Fixed a bug: Now the Voronoi diagram/Delaunay
            triangulation is also available for Growing Grid.
15.10.1996: New method Growing Grid.
14.10.1996: Added a new class GridNodeGNG to gain a grid covering
            the nodes. 
09.10.1996: Added a new menu for speed. Now it is possible to switch
            to an individual speed depending on the machine and/or
            browser. (On some machines there was no interaction
            possible with the default value. On the other hand, why
            longer waiting than necessary?) 
04.10.1996: Added an error graph. (The source of this class was
            written by Christian Kurzke and Ningsui Chen. I have
            only made minor changes to this class. Many thanks to
            Christian Kurzke and Ningsui Chen for this nice
            graph class.)
30.09.1996: Added a new frame in a separate window for the error
            graph (new class GraphGNG).
30.09.1996: New checkboxes to turn the nodes/edges on and off.
26.09.1996: Fixed again all known bugs.
25.09.1996: Finished the discrete distribution (mainly for LBG).
24.09.1996: Default no sound.
20.09.1996: Fixed all known bugs (Can you find some unknown?).
19.09.1996: Prepared for new distribution (a discrete one with 500
            fixed signals).
10.09.1996: New method LBG (some minor bugs are known, but not
            concerning the method).
03.09.1996: Renamed class PanelGNG to a more convenient name
            (ComputeGNG).
02.09.1996: Split the source file DemoGNG.java. Now each class has
            its own file.
01.09.1996: Inserted more comments.
30.08.1996: Cleaned up the code to compute the Voronoi
            diagram/Delaunay triangulation.
07.08.1996: Added Delaunay triangulation (press checkbutton
            Delaunay)!
06.08.1996: Now you can display Voronoi diagrams for each method
            (press checkbutton Voronoi)!


21.06.1996: Version 1.0 released.
