Many recent object recognition systems use a small number of pairings of data and model features to compute the 3D transformation from a model coordinate frame into the sensor coordinate system. In the case of perfect image data, these systems seem to work well. With uncertain image data, however, the performance of such methods is less well understood. In this paper, we examine the eeects of t...

Decisions in the environmental and in particular the climate domain are burdened with uncertainty. Here, we focus on uncertainties faced by individuals when making decisions about environmental behavior, and we use the statistical sampling framework to develop a classification of different sources of uncertainty they encounter. We then map these sources to different public policy strategies aim...

We describe an efficient method for path planning in environments for which prior maps are plagued with uncertainty. Our approach processes the map to determine key areas whose uncertainty is crucial to the planning task. It then incorporates the uncertainty associated with these areas using the recently developed PAO* algorithm to produce a fast, robust solution to the original planning task. ...

This paper describes the use of a set inversion algorithm to solve the problem of mobile robot localization. The method is based on the formalism of interval analysis. In this formalism, an imprecise number is represented by an interval which contains it in a guaranteed way. This enables to naturally manage the imprecision linked to the mobile robot configuration. Indeed, we show that imprecisi...

In the English clinical and biomedical text domains, negation and certainty usage are two well-studied phenomena. However, few studies have made an in-depth characterization of uncertainties expressed in a clinical setting, and compared this between different annotation efforts. This preliminary, qualitative study attempts to 1) create a clinical uncertainty and negation taxonomy, 2) develop a ...

Land cover plays a significant role in the earth system science, which reflects the influence of human activities and environmental changes (Sellers et al., 1997; IGBP, 1990; Aspinall et al, 2004). In China, Many land use/cover maps can be used in recent years derived from remote sensing observation. These data will be whether or how combined effectively to produce better land cover map that is...

This papers provides two contributions to the problem of Simultaneous Localization and Mapping (SLAM): First we discuss properties of the problem itself and of the intended semantics of an uncertain map representation, with the main idea of “representing certainty of relations despite the uncertainty of positions”. We propose some requirements an ideal solution of SLAM should have concerning un...
