This paper proposes a robust global linearization filter design for a nonlinear stochastic system with exogenous disturbance. The nonlinear dynamic system is modeled by Itocirc-type stochastic differential equations. For a general nonlinear stochastic system with exogenous disturbance, the robust <i>H</i> <sub>infin</sub> filter can be obtained by solving a(More)
We investigate an <i>H</i><sub>&#x221E;</sub> robust observer-based stabilization design problem for linear stochastic partial differential systems (LSPDSs) under spatio-temporal disturbances and sensor measurement noises. A general theoretical <i>H</i><sub>&#x221E;</sub> robust observer-based stabilization method is introduced at the beginning for LSPDSs(More)
This study addresses a robust <i>H</i><sub>&#x221E;</sub> filtering design problem for linear stochastic partial differential systems (LSPDSs) with external disturbance and measurement noise in the spatio-temporal domain. For LSPDSs, the robust <i>H</i><sub>&#x221E;</sub> filter design via a set of sensor measurements needs to solve a complex Hamilton(More)
This paper discusses the nonlinear stochastic H<sub>2</sub>/H<sub>&#x0221E;</sub> output feedback control design with state-dependent noise. Our results extend the linear stochastic H<sub>2</sub>/H<sub>&#x0221E;</sub> control to the nonlinear output feedback case. First, based on stochastic Nash game theory, an observer-based nonlinear stochastic(More)
PageRank has been the signature unsupervised ranking model for ranking node importance in a graph. One potential drawback of PageRank is that its computation depends only on input graph structures, not considering external information such as the attributes of nodes. This work proposes AttriRank, an unsupervised ranking model that considers not only graph(More)
This study addresses a robust <i>H</i><sub>&#x221E;</sub> filter design problem for nonlinear stochastic partial differential systems (NSPDSs) with random external disturbance and measurement noise in the spatiotemporal domain. For NSPDSs, a robust <i>H</i><sub>&#x221E;</sub> filter design through a set of sensor measurements needs to solve a complex(More)
In this study, in order to generate a sequence of desired quantum states (or quantum bits) for quantum communication and computation, it is more appealing to formulate a quantum control system as a bilinear state reference tracking system. An optimal tracking control is proposed to achieve the state-tracking by solving a Hamilton-Jacobi equation (HJE). In(More)
We investigate an unsupervised generative approach for network embedding. A multi-task Siamese neural network structure is formulated to connect embedding vectors and our objective to preserve the global node ranking and local proximity of nodes. We provide deeper analysis to connect the proposed proximity objective to link prediction and community(More)
