We propose a multi‐strategic concept‐spotting approach for robust spoken language understanding of conversational Korean in a hostile recognition environment such as in‐car navigation and telebanking services. Our concept‐spotting method adopts a partial semantic understanding strategy within a given specific domain since the method tries to directly extract pre‐defined meaning representation slot values from spoken language inputs. In spite of partial understanding, we can efficiently acquire the necessary information to compose interesting applications because the meaning representation slots are properly designed for specific domain‐oriented understanding tasks. We also propose a multi‐strategic method based on this concept‐spotting approach such as a voting method. We present experiments conducted to verify the feasibility of these methods using a variety of spoken Korean data. 相似文献

We consider disturbed linear 2D-systems of Fornasini–Marchesini type in the continuous time case. These systems are also named
Goursat-type systems. Conditions for unique solvability of the disturbed optimal control problem with a quadratic cost functional
are obtained. The disturbed or worst case optimal control guarantees to minimize the cost functional for any unknown disturbance
input. In a second part then we consider a disturbance attenuation by boundary controls, i.e., by using the Goursat-data as
control functions. In the 2D-case this results in two control functions acting independently on the system. We study a cooperative
and a non-cooperative situation. In the cooperative situation we again obtain a disturbed optimal control problem and get
conditions for existence and uniqueness of such a disturbed optimal control problem. If the action of the agents is non-cooperative
we assume that it is agreed that they act on an open-loop Nash/worst-case equilibrium strategy. Sufficient conditions for
the existence of such an equilibrium are obtained.

In this paper, the single machine sequencing problem with maximum lateness criterion is discussed. The parameters of the problem are imprecise and they are specified as intervals. The maximal regret criterion is applied to calculate the optimal sequence. A polynomial algorithm for the studied problem is constructed. 相似文献

We present a numerical study concerning the defocusing mechanism of isochronous resonance island chains in the presence of two permanent robust tori. The process is initialized and concluded through bifurcations of fixed points located on the robust tori. Our approach is based on a Hamiltonian system derived from the resonant normal form. Choosing a convenient parameter in this system, we are able to depict a comprehensive analysis of the dynamics of the problem. 相似文献

We discuss an approach for solving the Bilinear Matrix Inequality (BMI) based on its connections with certain problems defined
over matrix cones. These problems are, among others, the cone generalization of the linear programming (LP) and the linear
complementarity problem (LCP) (referred to as the Cone-LP and the Cone-LCP, respectively). Specifically, we show that solving
a given BMI is equivalent to examining the solution set of a suitably constructed Cone-LP or Cone-LCP. This approach facilitates
our understanding of the geometry of the BMI and opens up new avenues for the development of the computational procedures
for its solution.

We show that for even quasi-concave objective functions the worst-case distribution, with respect to a family of unimodal
distributions, of a stochastic programming problem is a uniform distribution. This extends the so-called ``Uniformity Principle'
of Barmish and Lagoa (1997) where the objective function is the indicator function of a convex symmetric set. 相似文献

Stability radii for linear time-varying differential-algebraic equations with respect to dynamic perturbations 总被引:1,自引:0,他引:1
Nguyen Huu Du 《Journal of Differential Equations》2006,230(2):579-599
This paper is concerned with the robust stability for linear time-varying differential-algebraic equations. We consider the systems under the effect of uncertain dynamic perturbations. A formula of the structured stability radius is obtained. The result is an extension of a previous result for time-varying ordinary differential equations proven by Birgit Jacob [B. Jacob, A formula for the stability radius of time-varying systems, J. Differential Equations 142 (1998) 167-187]. 相似文献
