The purpose of this paper is to discribe a direct design approach using a GA(Genetic Algorithm) to a HSTF(Hicarchical Structure Transversal Filter). A direct design approach of the HSTF is not easy because of highly nonlinear problem. So far. we took a two phase approach. However, this approach cannot give an accurate specification of the filter. We applied a GA into a direct design of the HSTF and...
We have proposed an efficient approach to manage a dialog system using a weighted finite-state transducer (WFST) in which users?? concept and system??s action tags are input and output of the transducer, respectively. A WFST for dialog management was automatically created using a corpus annotated with inter-change format (IF) consisting of dialog acts and argument which is an interlingua for machine...
We are proceeding with the development of a multi-processor version of a traffic simulator. Windows multi-display feature resembles our system in the point that multi-displays are used. So we made performance comparison between them. Finally we verified our multi-processor version is almost two times faster than Windows multi-display feature in the case of two displays.
Todaypsilas access network is migrating towards broadband IP, fixed/mobile convergence and service convergence. Thus, the next generation access network (NGAN) requires a converged optical/wireless access network infrastructure, other than the existing architecture that connect to the cellular, broadband wireless, and optical access networks separately, which complicate the network and increase the...
