Abstract. In this contribution a dual representation of spatio-temporal phenomena whose observation is affected by uncertainty is proposed in the context of fuzzy set and possibility theory. The concept of fuzzy time validity of a snapshot of a dynamic phenomenon is introduced as well

be equivalent as Z-representations. For instance, the integral representation of W (PU(n)) is not equivalent to that of W (SU(n)). LetW (G) ∗ denote the dual representation ofW (G). Then we seeW (PU(n)) = W (SU(n)) ∗ [11]. Turning to the rings of invariants, for the cohomology of classifying spaces BG

To use a symbolic object such as a model, map, or picture, one must achieve dual representation; that is, one must mentally represent both the symbol itself and its relation to its referent. The studies reported here confirm predictions derived from this concept. As hypothesized, dual

Abstract: We provide primal and dual representations for the tracking error in the official monetary aggregates published by the Federal Reserve System from the standpoint of monetary aggregation theory. We show that the tracking error will be zero if either all asset stocks or their prices change

and phonological representations that capture better the relevant structure among the written and spoken forms of words. In a number of simulation experiments, networks using the new representations learn to read both regular and exception words, including low-frequency exception words, and yet are still able

It is well known that any non-binary CSP can be reformulated as a binary CSP. In this paper we show that the same translation methods can be applied in the soft constraints framework. We observe that any non-binary soft constraint CSP can be reformulated as a problem with only binary and unary constraints. Interestingly, the translation leads to binary constraints that are hard (define conditions of mandatory satisfaction) and unary constraints that are soft (define a preference criterion among the set of solutions). We elaborate our observation in the semiringbased framework.

MatrixExplorer is a network visualization system that uses two representations: node-link diagrams and matrices. Its design comes from a list of requirements formalized after several interviews and a participatory design session conducted with social science researchers. Although matrices

A constructivist neural network is presented that models impaired inectional processing in German agrammatic aphasia. The model is based on a single mechanism and develops two types of representation through a constructivist learning process. The model accounts for data that has been taken
