  • Chang, Allan; Amir, Eyal (2005-11)
    We present new algorithms for learning a logical model of actions' effects and preconditions in partially observable domains. The algorithms maintain a logical representation of the set of possible action models after each ...

  • Vardhan, Abhay; Viswanathan, Mahesh (2005-08)
    We present a new model checking algorithm for verifying computation tree logic (CTL) properties. Our technique is based on using language inference to learn the fixpoints necessary for checking a CTL formula instead of ...

  • Cai, Deng; He, Xiaofei; Han, Jiawei (2006-04)
    Most of the existing learning algorithms take vectors as their input data. A function is then learned in such a vector space for classification, clustering, or dimensionality reduction. However, in some situations, there ...

  • Amir, Eyal; Russell, Stuart (2005-05)
    Filtering denotes any method whereby an agent updates its belief state - its knowledge of the state of the world - from a sequence of actions and observations. In logical filtering, the belief state is a logical formula ...

  • Pellizzoni, Rodolfo; Caccamo, Marco (2006-03)
    Resource reclaiming schemes are applied in reservation-based real-time uniprocessor systems to support efficient reclaiming and sharing of computational resources left unused by early completing tasks, improving the response ...

  • Agarwal, Shivani; Roth, Dan (2003-12)
    We develop an approach for automatically learning the optimal feature transformation for a given classification problem. The approach is based on extending the principle of risk minimization (RM), commonly used for learning ...

  • Conner, William G.; Nahrstedt, Klara (2008-07)
    As Internet telephony systems continue to replace existing Public Switched Telephone Network systems, proxy servers running the Session Initiation Protocol (SIP) will continue to grow in importance for Voice-over-IP ...

  • Pae, Sung-il (2005-05)
    We study random number generation using a biased source motivated by previous works on this topic, mainly, von Neumman (1951), Elias (1972), Knuth and Yao (1976) and Peres (1992). We study the problem in two cases: first, ...

  • Cheng, Peng (2005-08)
    Kinodynamic and nonholonomic planning problems have differential constraints which restrict admissible velocities and accelerations of robotic systems. Since these differential constraints are ignored in the path planning ...

  • Bunde, David Pattison (2006-07)
    We present algorithms and hardness results for three resource allocation problems. The first is an abstract admission control problem where the system receives a series of requests and wants to satisfy as many as possible, ...

  • Cai, Deng; He, Xiaofei; Han, Jiawei (2007-05)
    Spectral methods have recently emerged as a powerful tool for dimensionality reduction and manifold learning. These methods use information contained in the eigenvectors of a data affinity (\ie, item-item similarity) matrix ...

  • Cai, Deng; He, Xiaofei; Han, Jiawei (2007-05)
    Linear Discriminant Analysis (LDA) has been a popular method for extracting features which preserve class separability. The projection functions of LDA are commonly obtained by maximizing the between class covariance and ...

  • Xue, Yuan; Cui, Yi; Nahrstedt, Klara (2005-06)
    Energy efficient routing is a critical problem in multihop wireless networks due to the severe power constraint of wireless nodes. Despite its importance and many research efforts towards it, a distributed routing algorithm ...

  • VanderZee, Evan; Hirani, Anil N.; Guoy, Damrong; Ramos, Edgar (2008-02)
    Well-centered meshes (meshes composed of well-centered simplices) have the advantage of having nice orthogonal dual meshes (the dual Voronoi diagram), which is useful for certain numerical algorithms that require or prefer ...

  • Lim, Hyuk; Kung, Lu-Chuan; Hou, Jennifer C.; Luo, Haiyun (2005-08)
    With the technical advances in ubiquitous computing and wireless networking, there has been an increasing need to capture the context information (such as the location) and to figure it into applications. In this paper, ...
