CHREST: AVOW Diagrams
A customised version of CHREST which learns chunks from AVOW diagrams.
CHREST is a symbolic cognitive architecture, and AVOW diagrams are a representational system for understanding electric circuits.
The project resulted in two directly-related publications:
- P.C.R. Lane, P.C-H. Cheng and F. Gobet, 'CHREST+: Investigating how humans learn to solve problems with diagrams,' AISB Quarterly, 103:24-30, 2000.
- P.C.R. Lane, P.C-H. Cheng and F. Gobet, 'Learning perceptual chunks for problem decomposition', in Proceedings of the Twenty-Third Annual Conference of the Cognitive Science Society, pp. 528-33, 2001.
Code
The implementation was initially written around 1998-2001 in MCL Lisp, with a graphical-user interface.
I have rewritten the code to be an ASDF-installable package with tests. Currently, the former tests still pass, but there is no graphical-user interface.
To install, download the latest release and make the code available to the asdf system.
- Depends on
- alexandria and LTk
The API documentation is currently scanty, but what there is means it is best built using baruch - or read here.
