In the case of binary state reliability system, importance measures of components consisting a system, such as structural importance measure, Birnbaum importance measure, criticality importance measures and some other importance measures, have been proposed and used effectively for practical risk and safety problems. When we want to judge which component or factor should be maintained first to ...

Speckle noise (salt and pepper) is inherent to synthetic aperture radar (SAR), which causes a usual noise-like granular aspect and complicates the image classification. In SAR image analysis, the spatial information might be a particular benefit for denoising and mapping classes characterized by a statistical distribution of the pixel intensities from a complex and heterogeneous spectral respon...

We investigate the use of multi-stream HMMs in the automatic recognition of audio-visual speech. Multi-stream HMMs allow the modeling of asynchrony between the audio and visual state sequences at a variety of levels (phone, syllable, word, etc.) and are equivalent to product, or composite, HMMs. In this paper, we consider such models synchronized at the phone boundary level, allowing various de...

Differential evolution (DE) research for multi-objective optimization can be divided into proposals that either consider DE as a stand-alone algorithm, or see DE as an algorithmic component that can be coupled with other algorithm components from the general evolutionary multiobjective optimization (EMO) literature. Contributions of the latter type have shown that DE components can greatly impr...

This paper is concerned with the architectural design and development of a spoken dialogue platform for robots. The platform adopts modular software architecture and event driven communication paradigm which makes speech enabled hardware devices and software components configurable and reusable. The platform is able to integrate heterogeneous dialogue components (such as speech recognizer, natu...
