- Example: artmap.xxx ARTMAP letters network

-
- Problem description:
- ====================
-
- The ARTMAP letters network shows the supervised classification of
- input patterns by an ARTMAP network. The ARTMAP network consits of two
- ART1 networks combined by a MAP-field. The input patterns are similar
- to the patterns of the 'letters' pattern file, except that these
- patterns are in 'complement coding' notation, i.e. there exists an
- original 5x7 input matrix representing capital letters and its
- inverse, combined into (5*7)+(5*7) = 70-dimensional vector. The
- desired output is coded by the last 5 elements of each input pattern,
- giving a 75-dimensional input pattern alltogether. (for
- implementation reasons this desired output is given here as an
- additional component of the input).
-
- See the SNNS user manual for a more detailed description of the ARTMAP
- implementation in SNNS.
-
-
- Pattern-Files: artmap.pat
- ==============
-
- The pattern-file letters.pat contains 26 binary input patterns with values
- of 0 and 1 representing capital letters in a 5x7 input matrix.
-
-
- Network-Files: artmap.net
- ==============
-
- This network file contains a trained ARTMAP network for the letter
- classification task described above. The standard configuration file
- for this network is artmap.cfg (one 2D display only).
-
- You may generate your own ARTMAP network with the BIGNET tool from the
- Info-Panel of SNNS. This automatically generates all units and the
- necessary connections.
-
- Because the unit types and link structure are highly specialized in
- ARTMAP we strongly urge you only to use this tool to generate ARTMAP
- networks in SNNS.

- Hints:
- ======
-
- Read the chapter about ARTMAP in the SNNS manual very carefully!
-
- Note that ARTMAP needs a special network initialization function
- (REMOTE panel: OPTIONS select init function: ARTMAP_Weights).
- Note that there exist two different ARTMAP update functions:
- (REMOTE panel: OPTIONS select update function: ARTMAP_Synchronous
- or ARTMAP_Stable)
- Note that ARTMAP needs a special learning function:
- (REMOTE panel: OPTIONS select learning function: ARTMAP)
- These should already be set when loading the example ARTMAP network.
-
-
- There exists additional documentation in form of the diploma
- thesis of Kai-Uwe Herrmann (in German), available via anon. ftp
- from our public ftp server ftp.informatik.uni-stuttgart.de under
- /pub/SNNS/NN-papers-german/herrmann_kaiuwe_DA.ps.Z
