چکیده

In this paper we describe a. framework for model-based diagnosis of dynamic systems, which extends previous work in this field by using and expressing temporal uncertainty in the form of qualitative interval relations a la Allen. Based on a logical framework ex­ tended by qualitative and quantitative tem­ poral constraints we show how to describe behavioral models (both consistencyand abductive-based), discuss how to use abstract observations and show how abstract tempo­ ral diagnoses are computed . This yields an expressive framework, which allows the rep­ resentation of complex temporal behavior al­ lowing us to represent temporal uncertainty. Due to its abstraction capabilities computa­ tion is made independent of the number of observations and time points in a temporal setting. An example of hepatitis diagnosis is used throughout the paper.

Qualitative and Quantitative Probabilistic Temporal Reasoning - for Industrial Applications

Many real-world domains, such as industrial diagnosis, require an adequate representation that combines uncertainty and time. Research in this field involves the development of new knowledge representation and inference mechanisms to deal with uncertainty and time. Current temporal probabilistic models become too complex when used for real world applications. In this paper, we propose a model, ...

Temporal Matching under Uncertainty

Temporal matching is the problem of matching observations to predeened temporal patterns or templates. This problem arises in many applications including medical and model-based diagnosis, plan-recognition, and temporal databases. This work examines the sources of uncertainty in temporal matching and presents a probabilistic technique to perform temporal matching under uncertainty. This techniq...

Abstract temporal diagnosis in medical domains

Most current model-based diagnosis formalisms and algorithms are defined only for static systems, which is often inadequate for medical reasoning. In this paper we describe a model-based framework plus algorithms for diagnosing time-dependent systems where we can define qualitative temporal scenarios. Complex temporal behavior is described within a logical framework extended by qualitative temp...

Preventing the frequency of infectious diseases in vulnerable groups - by anticipating the role of actors in implementing the decision-making model in conditions of uncertainty Pandemic experience Covid-19

Background: The purpose of this study is to prevent the prevalence of infectious diseases in vulnerable groups by anticipating the role of actors in implementing decision-making models in conditions of uncertainty in medical universities. Methods: This research is an applied research by combining qualitative and quantitative methods based on the foundation data theory (Grand Theory). To determ...
