A Discrete Model for Color Naming

G. Menegaz, A. Le Troter, J. Sequeira, J. M. Boi
2006 EURASIP Journal on Advances in Signal Processing  
In this paper, we propose a discrete model for computational color categorization and naming.  ...  The discrete model consists of a three-dimensional Delaunay triangulation of the CIELAB color space which associates each OSA-UCS sample to a vertex of a 3D tetrahedron.  ...  ACKNOWLEDGMENT We thank Professor Hubert Ripoll for his hints and stimulating discussion.  ...

Subsequently, a third factor was added to the model, i.e., naming of discrete digits.  ...  The model prediction was higher (from ca. 37 to 52% of the explained variance) when we included the naming of discrete digits variable, which had a suppressive effect on pseudo-word reading.  ...  Claudio Barbaranelli, Kim Nimon and Silvia Primativo for their advice and help with the statistical analyses, Maria Pontillo for help in data collection, and Claire Montagna for the linguistic revision  ...

Communicating artificial neural networks develop efficient color-naming systems

Rahma Chaabouni, Eugene Kharitonov, Emmanuel Dupoux, Marco Baroni
2021 Proceedings of the National Academy of Sciences of the United States of America  
Like human languages, emergent systems show a preference for relatively low-complexity solutions, even at the cost of imperfect communication.  ...  The observed variation among emergent color-naming systems is explained by different degrees of discriminative need, of the sort that might also characterize different human communities.  ...  We thank Emmanuel Chemla, Thomas Brochhagen, Roger Levy, Louise McNally, Rachid Riad, Noga Zaslavsky, the PNAS reviewers, and, especially, Gemma Boleda and Diane Bouchacourt for feedback.  ...

Additive Factors Do Not Imply Discrete Processing Stages: A Worked Example Using Models of the Stroop Task

Tom Stafford, Kevin N. Gurney
2011 Frontiers in Psychology  
Further, our modeling work suggests that information binding may be a more important architectural property for producing additive factors than discrete stages.  ...  We present computational modeling work, using an existing Parallel Distributed Processing model of the Stroop task (Cohen et al., 1990 ) and a standard model of decision making (Ratcliff, 1978) .  ...  spell out the names of colors.  ...
