    A Cyber-Physical System (CPS) integrates physical devices (i.e., sensors) with cyber (i.e., informational) components to form a context sensitive system that responds intelligently to dynamic changes in real-world situations. Such a system has wide applications in the scenarios of traffic control, battlefield surveillance, environmental monitoring, and so on. A core element of CPS is the collectio... View full abstract»

    The ubiquity of smartphones together with their ever-growing computing, networking, and sensing powers have been changing the landscape of people's daily life. Among others, activity recognition, which takes the raw sensor reading as inputs and predicts a user's motion activity, has become an active research area in recent years. It is the core building block in many high-impact applications, rang... View full abstract»

  • Efficient view-based 3-D object retrieval via hypergraph learning

    Publication Year: 2014, Page(s):250 - 256
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (2085 KB)

    View-based 3-D object retrieval has become an emerging topic in recent years, especially with the fast development of visual content acquisition devices, such as mobile phones with cameras. Extensive research efforts have been dedicated to this task, while it is still difficult to measure the relevance between two objects with multiple views. In recent years, learning-based methods have been inves... View full abstract»

  • Semiparametric preference learning

    Publication Year: 2014, Page(s):257 - 264
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (1465 KB)

    Unlike traditional supervised learning problems, preference learning learns from data available in the form of pairwise preference relations between instances. Existing preference learning methods are either parametric or nonparametric in nature. We propose in this paper a semiparametric preference learning model, abbreviated as SPPL, with the aim of combining the strengths of the parametric and n... View full abstract»

    A current trend for online social networks is to turn mobile. Mobile social networks directly reflect our real social life, and therefore are an important source to analyze and understand the underlying dynamics of human behaviors (activities). In this paper, we study the problem of activity prediction in mobile social networks. We present a series of observations in two real mobile social network... View full abstract»

  • An integrated workflow for proteome-wide off-target identification and polypharmacology drug design

    Publication Year: 2014, Page(s):275 - 284
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (686 KB)

    Polypharmacology, which focuses on designing drugs to target multiple receptors, has emerged as a new paradigm in drug discovery. To rationally design multi-target drugs, it is fundamental to understand protein-ligand interactions on a proteome scale. We have developed a Proteome-wide Off-target Pipeline (POP) that integrates ligand binding site analysis, protein-ligand docking, the statistical an... View full abstract»

    Multiple-Instance Learning (MIL) is used to predict the unlabeled bags' label by learning the labeled positive training bags and negative training bags. Each bag is made up of several unlabeled instances. A bag is labeled positive if at least one of its instances is positive, otherwise negative. Existing multiple-instance learning methods with instance selection ignore the representative degree of... View full abstract»

    A hybrid collaborative filtering algorithm based on the user preferences and item features is proposed. A thorough investigation of Collaborative Filtering (CF) techniques preceded the development of this algorithm. The proposed algorithm improved the user-item similarity approach by extracting the item feature and applying various item features' weight to the item to confirm different item featur...

    With rapid urbanization, subway systems are widely acknowledged as one of the best solutions to urban transportation problems. The operators or managers of subway systems should pay more attention to passenger's perceptions of service quality to maintain its competitive position. Taking the traffic state, efficiency, and environmental impact into consideration, the concept of generalized comfort i... View full abstract»

  • The extended linear-drift model of memristor and its piecewise linear approximation

    Publication Year: 2014, Page(s):307 - 313

    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (3746 KB)

    Memristor is introduced as the fourth basic circuit element. Memristor exhibits great potential for numerous applications, such as emulating synapse, while the mathematical model of the memristor is still an open subject. In the linear-drift model, the boundary condition of the device is not considered. This paper proposes an extended linear-drift model of the memristor. The extended linear-drift ...

    In this paper, we propose a new algorithm to establish the data association between a camera and a 2-D LIght Detection And Ranging sensor (LIDAR). In contrast to the previous works, where data association is established by calibrating the intrinsic parameters of the camera and the extrinsic parameters of the camera and the LIDAR, we formulate the map between laser points and pixels as a 2-D homogr...
