A multi-phone unit specification for unit selection speech synthesis is introduced and tested with regard to its qualitative aspects by means of a listening experiment. This different concept of unit definition aims to prevent spectral discontinuities at highly critical points of concatenation and to allow for a faster creation of speech corpora, as well as a speed-up of cost calculation and un...

In the last years, a lot a research have been done in the field of inverse lighting (and, in a neighbouring domain: inverse rendering – or relighting). However the proposed tools for inverse lighting are not intuitive or are too limited. Our aim is to present a framework for a declarative specification of the lighting of a scene. The concepts and properties relevant to a qualitative description...

A high-level ASM specification of Condor, a system providing powerful methods for managing beliefs induced by general conditionals, is refined to qualitative conditional logics, leading to an ASM implementation. The semantics of this logic are given by ordinal conditional functions (OCFs) ordering worlds according to their plausibility. OCFs are used to represent the epistemic state of an agent...

The state-of-the art of psychological knowledge about the personality types is distilled to provide a basis for the specification of fuzzy agents with dynamic personality for the simulation of human behavior. The thirty facets, clustered in five traits (or, factors) to determine the personality types are outlined. Three concise representations of the primary characteristics of human personality...

Probabilistic expert systems based on Bayesian networks (BNs) require initial specification both a qualitative graphical structure and quantitative assessment of conditional probability tables. This paper considers statistical batch learning of the probability tables on the basis of incomplete data and expert knowledge. The EM algorithm with a generalized conjugate gradient acceleration method ...

Constraint programming holds many promises for model driven software development (MDSD). Up to now, constraints have only started to appear in MDSD modeling languages, but have not been properly reflected in model transformation. This paper introduces constraint programming in model transformation, shows how constraint programming integrates with QVT Relations as a pathway to wide spread use of...
