Welcome to catlearn project!

Computational modelling of formal psychological theories.

catlearn logo

Catlearn is a framework and archive for distributed collaboration in formal modeling of categorization and learning in psychology. It provides an archival record of:

  1. Canonical Independently Replicated Phenomena (i.e. key datasets),
  2. formal models
  3. simulations.
It supplements, rather than supplants, journal article publication.

CRG = Catlearn Research Group

Invite us to give a talk or workshop?

The Catlearn Research Group are keen to talk about the catlearn project to any interested party (academic or non-academic). Why not invite us to give a talk or run a workshop where you are? We do not charge an appearance fee, but would prefer it if you were able to reimburse our travel expenses, including accommodation.

The Catlearn Research Group are based in the United Kingdom, at Plymouth University [map]
