Connectionist neural networks are useful geometric models of categorization.
Our design and analysis allow us to distinguish between different sources of complexity and theoretical models of categorization.
Modern machine learning methods and psychological models of categorization are remarkably similar, partly because these two fields share a common history in artificial neural networks and reinforcement learning.
Neurobiological models of categorization have suggested that the caudate nucleus, together with interconnected cortical and subcortical structures, contributes to the maintenance and switching of rules that guide categorization (Maddox and Ashby, 2004; Ashby and Ennis, 2006).
The CPDB rodent carcinogenic database was used for development of models for categorization of carcinogenic potency.
Further, so that comparisons can be made between the Centre's work, its relationship to national policies and programmes and relevance to global trends, the Centre should consider adopting a more globally accepted model of research categorization such as those described in Donald Stoke's Pasteur's Quadrant [ 11] or Buxton and Hanney's Payback Framework [ 12].
Tumors were categorized histologically using the recommendations of the Mouse Models of Human Cancers Consortium categorization scheme [ 17- 19] and the specific nomenclature applying to certain models [ 22] or tumor types [ 21, 23] when applicable.
The results were considered in relation to the following models of unsupervised categorization: DIVA, the rational model, the simplicity model, SUSTAIN, an Unsupervised version of the Generalized Context Model (UGCM), and a simple geometric model based on similarity.
Additive, recessive, and dominant models of allele categorization were tested.
The second is a clinical definition of inhalational melioidosis, which has value for preparedness planning for deliberate B. pseudomallei release, design of experimental models, and categorization of routes of infection for naturally acquired melioidosis.
