The combination of evidence in Dempster-Shafer theory is compared with the combination of evidence in probabilistic logic. Sufficient conditions are stated for these two methods to agree. It is then shown that these conditions are minimal in the sense that disagreement can occur when any one of them is removed. An example is given in which the traditional assumption of conditional independence ...

In this note, we argue that the axiomatic requirement of range to the measure of aggregated total uncertainty (ATU) in Dempster-Shafer theory is not reasonable.

In the paper λ-method Mitrinovi´c-Vasi´c is applied aiming to improve Fink's inequality, and Shafer's inequality for arcus sinus function is observed. In monography [1, p. 247] Shafer's inequality is stated: (1) 3x 2 + √ 1 − x 2 ≤ asin x (0 ≤ x ≤ 1). The equality holds only for x = 0. In paper [2] Fink has proved the inequality: (2) asin x ≤ πx 2 + √ 1 − x 2 (0 ≤ x ≤ 1). The equality holds at b...

Natural human activities involve using and manipulating objects, often several at a time, simultaneously and continuously. For example, changing lanes while driving requires using a steering wheel and pedals, all while observing the road and making sure that lanes are clear. Not only are we recognizing these objects, but we know what to do with them (i.e., we can perceive object affordances). W...

In pattern analysis, information regarding an object can often be drawn from its surround­ ings. This paper presents a method for handling uncertainty when using context of symbols and texts for analyzing technical drawings. The method is based on Dempster-Shafer theory and possibility theory. 1 Introduction In several pattern analysis problems it is interesting to look at the context in which ...
