Categorical models for local names

Ian Stark
1996 LISP and Symbolic Computation  
This paper describes the construction of categorical models for the nu-calculus, a language that combines higher-order functions with dynamically created names.  ...  Categorical monads, in the style of Moggi, are used to build denotational models for the nu-calculus.  ...  Acknowledgements Andy Pitts and Eugenio Moggi gave much advice on the methods used here, and Bob Tennent explained how they relate to his models of Algol-like languages.  ...

Evolutionary models of color categorization I Population categorization systems based on normal and dichromat observers

Kimberly A. Jameson, Natalia L. Komarova
2009 Optical Society of America. Journal A: Optics, Image Science, and Vision  
The evolution of color categorization is investigated using artificial agent population categorization games, by modeling observer types using Farnsworth-Munsell 100 Hue Test performance to capture human  ...  In particular, it is found that dichromats' local confusion regions tend to repel color category boundaries and that global confusion pairs attract category boundaries.  ...  ACKNOWLEDGMENTS The authors thank Louis Narens and Ragnar Steingrimsson for helpful suggestions.  ...

Evolutionary models of color categorization based on Realistic observer models and Population heterogeneity

K. A. Jameson, N. L. Komarova
2010 Journal of Vision  
Consequences for evolved categorization solutions include that confusion patterns of a small fraction of color deficient agents break symmetries in population categorization solutions, and confine category  ...  variation across different forms of deficient agents systematically impacts category size and number; with stimulus pairs from dichromat global confusion axes tend to attract color boundaries, whereas local  ...  The authors thank Louis Naren and Ragnar Steingrimsson for helpful suggestions, and David Bimler for providing the Bimler, Jacobs & Kirkland [23] data.  ...

Categorical colour geometry

Lewis D. Griffin, Dimitris Mylonas, Panos Athanasopoulos
2019 PLoS ONE  
Data on the colour categories of English speakers was collected using online crowd sourcing - 1,000 subjects produced 20,000 unconstrained names for 600 colour stimuli.  ...  In this categorical metric the distance between two close colours is determined by the difference in the distribution of names that the subject population applied to them.  ...  In 5 we use the dataset to constrain a continuous model of naming across colour space. In 6 we compute the categorical metric from that model.  ...

Foraging in Semantic Fields: How We Search Through Memory

Thomas T. Hills, Peter M. Todd, Michael N. Jones
2015 Topics in Cognitive Science  
Thus, our results support a search process that does not use categorical information, but for which patch boundaries shift with each recall and local search is well described by a random walk in semantic  ...  When searching for concepts in memory-as in the verbal fluency task of naming all the animals one can think of-people appear to explore internal mental representations in much the same way that animals  ...  To test this, we fit models that added an additional local cue to the previous categorical and associative model versions, namely the item I tÀ2 , produced just before I tÀ1 (as long as it was also in  ...

Scene Categorization with Classified Codebook Model

Xu YANG, De XU, Songhe FENG, Yingjun TANG, Shuoyan LIU
2011 IEICE transactions on information and systems  
This paper presents an efficient yet powerful codebook model, named classified codebook model, to categorize natural scene category.  ...  The significant feature in our model is that it is beneficial for scene categorization, especially at small codebook size, while saving much computation complexity for quantization.  ...  Particularly, for the model of BCM, vector quantization maps each local feature x to one visual word by nearest neighbor matching, namely, VQ(x, V) = v j ⇔ dist(x, v j ) < dist(x, v i ) ( 1 ) where i ∈  ...

Color naming and categorization depend on distinct functional brain networks [article]

Katarzyna Siuda-Krzywicka, Christoph Witzel, Paolo Bartolomeo, Laurent Cohen
2020 bioRxiv   pre-print
Naming a color can be understood as an act of categorization, i.e. identifying it as a member of a category of colors that are referred to by the same name.  ...  But are naming and categorization equivalent cognitive processes, and consequently rely on the same neural substrates?  ...  We defined separate models for naming and categorization RTs.  ...

An agent-based approach for predictions based on multi-dimensional complex data☆

2006 Information Sciences  
This paper presents an agent-based approach to the identification of prediction models for continuous values from multi-dimensional data, both numerical and categorical.  ...  At the micro-level, each agent tries to build a local linear model with multi-linear regression by competing with others; then at the macro-level all surviving agents build the global model by introducing  ...  The "vendor name" attribute was treated as categorical data, with the others as numerical data. We used Root-Mean-Square Error (RM SE) to evaluate the performance of the prediction models.  ...

Dynamic search and working memory in social recall

Thomas T. Hills, Thorsten Pachur
2012 Journal of Experimental Psychology. Learning, Memory and Cognition  
On the basis of these data, we tested various computational models of memory search regarding their ability to account for the patterns in which participants recalled from social memory.  ...  Do the search mechanisms involve dynamic local-to-global transitions similar to semantic search, and are these transitions governed by the general control of attention, associated with working memory span  ...  Models Incorporating Different Global and Local Representations, and Different Switching Criteria (Associative or Categorical)Note.  ...
