A Temporal Extension to the ParsimoniousCovering
نویسنده
چکیده
In this work we propose a temporal extension to the Parsimonious Covering Theory (PCT). PCT provides a theoretical foundation for the diagnostic reasoning process as an abductive reasoning based associations between causes with their consequences. Our temporal extension of PCT allows one to associate to a disease a temporal evolution of its symptoms. The elimination of temporally inconsistent hypotheses minimizes one of the greatest problems of PCT: the solution for a particular diagnsotic problem may include a large number of alternative hypotheses. Furthermore , the inclusion of temporal aspects to an extension of PCT that includes probabilistic information also eliminates the problems of incorrectly rejecting hypotheses if a necessary symptom has not yet occurred.

A Fuzzy Temporal / Categorical Extension to the ParsimoniousCovering
This paper proposes a way of incorporating fuzzy temporal reasoning within diagnostic reasoning. Disorders are described as an evolving set of necessary and possible manifestations. The expected duration of each manifestation and the interval of time expected to occur between the beginning of any two manifestations are modeled by fuzzy sets. The patient information about the beginning and durat...
متن کاملAssessment of Spatial and Temporal Variability of Extreme Precipitation Indices (North and West of Iran)
The frequency of precipitation extreme event can cause flood or change the drought period. Accurate understanding of these changes is necessary to take action to reduce these effects. In this research, temporal and spatial changes of 14 precipitation indices for eight synoptic stations in the North and West of the country were investigated. For this purpose, after reconstructing the daily preci...

Abstract Introduction: Arachnoid cysts are developmental cystic lesions which may be found as an incidental finding on neuroimaging or present with symptoms of headache, seizure and neurologic deficit. Presentation with seizure is more common with larger sizes and temporal location. Presentation with TLE is rare, and fenestration of cysts had variable results for seizure control. Here in, we r...
متن کاملTemporal and spatial study of water use productivity of strategic crops in regional scale (Case study: Hamedan province)
Water use productivity is one of the most important factors in scientific agriculture. It is equal to 0. 7 kg of production per cubic meter of irrigation water (Kg/m3) in Iran which is very low in comparison with advanced countries (1 to 2 Kg/m3). Current research studies temporal and spatialchanges of water use productivity in Hamedan province in Iran using Geographic Information System (GIS),...
متن کامل4D PET: Beyond conventional dynamic PET imaging
In this paper, we review novel techniques in the emerging field of spatiotemporal 4D PET imaging. We will discuss existing limitations in conventional dynamic PET imaging which involves independent reconstruction of dynamic PET datasets. Various approaches that seek to attempt some or all of these limitations are reviewed in this work, including techniques that util...
