qYaditionally, constraint satisfaction problems (CSPs) are characterized using a finite set of constraints expressed within a common, shared constraint language. When reasoning across time, however, it is possible to express both temporal and state-based constraints represented within multiple constraint languages. Qualitative simulation provides an instance of this class of CSP in which, tradi...

Traditionally, constraint satisfaction problems (CSPs) are characterized using a nite set of constraints expressed within a common, shared constraint language. When reasoning across time, however, it is possible to express both temporal and state{based constraints represented within multiple constraint languages.

This is the second in a series of four papers on understanding and doing qualitative research [Frankel & Devers (2000) Qualitative research: a consumer's guide, Education for Health, 13, 113-123; Devers & Frankel (2000) Study design in qualitative research--2: sampling and data collection strategies, Education for Health, 13, 263-271]. Here, we focus on problems of study design, including quest...

We present further empirical and qualitative results for both image and video description. For the image description task, we explore averaging weight vectors before transfer, illustrate errors made by the model when no unpaired text data is used during training and provide descriptions generated by DCC for a large variety of novel object categories in ImageNet. For the video description task, ...

We present the description logic PN-ALCK NF for reasoning about actions with sensing under qualitative and probabilistic uncertainty, which is an extension of the description logic ALCK NF by actions with nondeterministic and probabilistic effects. We define a formal semantics of PN-ALCK NF in terms of deterministic, nondeterministic, and probabilistic transitions between epistemic states, whic...

The TEXRET-System, a texture retrieval system based on soft-computing technologies is being developed at University of Chile. One of its main features is that texture queries using human-like or qualitative description of textures are allowed. This human-like description of the textures was the subject of a psychological study that is described in this article. To our knowledge this is one the ...

Qualitative models provide the domain knowledge for qualitative reasoning systems, and the automatic generation of such models is an important knowledge acquisition task . Qualitative Simulation is a key qualitativ e reasoning technique . It is proposed that simulation systems like Kuipers ' QSIM [Kuipers 86] contain a powerful description language, based as they are on qualitativ e mathematics...

Most sensor based systems employ a large variety of sensors to obtain information. How the information obtained from different sensing devices is combined to form a description of the system is the sensor fusion problem. Most statistical sensor fusion systems use differential equations to inter-relate the values of sensor observations and system parameters . In this paper, we investigate model-...
