  • A collaborative filtering algorithm and evaluation metric that accurately model the user experience

    Creator:
    McLaughlin, Matthew
    Abstract:
    "Collaborative filtering algorithms’ performances have been evaluated using a variety of metrics. These metrics, such as Mean Absolute Error and Precision, have often ignored recommendations for which they do not have data. Ignoring these recommendations has provided numbers which do not accurately represent the user experience. Qualitatively we have seen...

  • Contributions to Collaborative Filtering Research

    Creator:
    Nong, Shuzhen
    Abstract:
    In this report, I first introduce three areas of interest to collaborative filtering researchers, namely: (a) how to solve the sparsity and scalability problems in recommendation systems; (b) how to rapidly develop and test collaborative filtering algorithms; and (c) how to apply collaborative filtering to unbounded numeric preference data. In...

  • Applying Deep Learning in Street View Imagery for Environmental Health Research

    Creator:
    Zhang, Yifang
    Abstract:
    Urban green space is associated with multiple physical and mental health outcomes. Several benefits of green space, such as stress reduction and attention restoration, are dependent on visual perception of green space exposures. However, traditional green space exposure measures do not capture street-level exposures. In this project, we apply deep...

  • Modeling architecture from photographs : an implementation of the Façade system

    Creator:
    Heath, Zach
    Abstract:
    The Façade photometric modeling system, developed by Paul E Debevec at Berkley, is capable of transforming a sparse set of camera images of an architectural scene into a photorealistic 3D model. Users define a rough model out of primitive building blocks and mark where a portion of the edges of...

  • Scoring Shape Characters of Monocot Leaves

    Creator:
    Zhou, Yao
    Abstract:
    Biologists regularly collect images of leaves for their further studies. One such biological study of leaves is scoring the phenomic characters of leaves for the construction of the Tree of Life (ToL), i.e. the evolutionary lineage of taxa in botany. There is an opportunity for computer vision to help biologists...

  • Structured network coding

    Creator:
    Saireddy, Balaji
    Abstract:
    Network coding is a transmission paradigm that is known to achieve better network throughput in certain multicast topologies; however, the practicality of network coding has been questioned due to its high computational complexity. One of the drawbacks of using network coding is the long decoding times, this is mainly due...

  • Natural language date-time parsing in Chandler™

    Creator:
    Chhajed, Darshana
    Abstract:
    The increasing need to share and synchronize personal information, such as schedules, tasks and events, amongst users has lead to the development of inter-personal information management software like ChandlerTM. Chandler is being developed in Python at the Open Source Applications Foundation, San Francisco. Before I started working on the project...

  • Interactive Methods for Authoring Behaviors of Multiple Agents

    Creator:
    Iyer, Vikram
    Abstract:
    Virtual environments and simulations are being used increasingly to both visualize and understand data as well as to create scenarios for training and analysis purposes. In this paper, we are interested in the use of simulation and visualization of interactive virtual agents to create realistic motions for training scenarios. We...
