چکیده

Abstract A novel solution to the smoothing problem for multi-object dynamical systems is proposed and evaluated. The of interest contain an unknown varying number objects that are partially observed under noisy corrupted observations. In order account lack information about different aspects this type complex system, alternative representation uncertainty based on possibility theory considered. It shown how analogues usual concepts such as Markov chains hidden models (HMMs) can be introduced in context. particular, considered statistical model multiple formulated a hierarchical consisting conditionally independent HMMs. This structure leveraged propose efficient method context chain Monte Carlo (MCMC) by relying approximate corresponding filtering problem, similar fashion particle MCMC. approach outperform existing algorithms range scenarios.

Computational Aspects of Resilient Data Extraction

Automatic data extraction from semistructured sources such as HTML pages is rapidly growing into a problem of significant importance, spurred by the growing popularity of the so called ”shopbots” that enable end users to compare prices of goods and other services at various web sites without having to manually browse and fill out forms at each one of these sites. The main problem one has to con...

Statistical Data Processing under Interval Uncertainty: Algorithms and Computational Complexity

Why indirect measurements? In many real-life situations, we are interested in the value of a physical quantity y that is difficult or impossible to measure directly. Examples of such quantities are the distance to a star and the amount of oil in a given well. Since we cannot measure y directly, a natural idea is to measure y indirectly. Specifically, we find some easier-to-measure quantities x1...

Fuzzy Techniques for Modelling Uncertainty in Medical Data and Knowledge

Fuzzy techniques may be used to represent uncertainty in both data and knowledge, and fuzzy inference systems (FISs) may be used to reason with such uncertain data and knowledge. In this paper, definitions are first provided for conventional type-1 fuzzy sets, more complex type-2 fuzzy sets and the recently introduced non-stationary fuzzy sets. Two medical applications in which such fuzzy sets ...
