  • Java implementation of a MathML rendering engine

    Creator:
    Dragunov, Anton N.
    Abstract:
    Current approaches to presentation of mathematics (on paper or in electronic format have usability drawbacks that make learning and appreciation of mathematics challenging and often frustrating. In a framework of a big research project of identifying new approaches to communicating mathematical ideas in a highly usable and effective manner, we...

  • Implementing a comparative anatomy information system for the foundational model of anatomy and the mouse anatomy ontology

    Creator:
    Diatchka, Kremena S.
    Abstract:
    This thesis describes the implementation of an interface for querying established correspondences between anatomical structures across species. I was the main developer of this query engine, called the Comparative Anatomy Information System. My work involved developing methods to query the knowledge base, perform the specified comparison, display the anatomical hierarchies...

  • SPEAR : Superlative Plagiarism Explorer And Reporter

    Creator:
    Pavithran, Siddharth
    Abstract:
    In this project, we have investigated three different techniques for plagiarism detection and have compared its effectiveness against that of an unaided human grader. The techniques investigated were word frequency analysis, sentence inclusion analysis and sub string inclusion analysis. We found that a combination of word frequency analysis and sub...

  • 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...

  • 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...

  • Collaborative filtering with probability and collaborative filtering with privacy

    Creator:
    Yang, Min
    Abstract:
    "Collaborative filtering has seen considerable success in the areas regarding information overload and e-commerce, while the current developed systems are flawed in several respects. Two approaches, the distribution-based algorithm and the blurring profile solution, are proposed to address several outstanding issues. The main findings of this research include: • The...

  • How to Render Mathematical Symbols in Java

    Creator:
    Sun, Yuemei
    Abstract:
    Current math software provides limited interactivity and dynamics when conveying math ideas. We are developing prototype Java toolkits to display math-embedded documents in a more dynamic and interactive way. The core task of current project is to create a Java implementation of a MathML (in which a math expression is...

  • Contributions to a Java recommender system

    Creator:
    Wang, Yun
    Abstract:
    Identifying the most relevant items in an e-commerce site is becoming more and more difficult nowadays because of the heavy overload of information. A Java Recommender System that uses Collaborative Filtering techniques has been developed to reduce such information overload and even personalize the information to the individual’s preference. The...

  • Designing and understanding information retrieval systems using collaborative filtering in an academic library environment

    Creator:
    Jung, Seikyung
    Abstract:
    Accessing information on the Web has become ingrained into our daily lives, and we seek information from many different sources, including conference and journal publications, personal web pages, and others. Increasingly, web-based information retrieval systems such as web-based search engines, library on-line catalog systems, and subscription-based federated search systems are...

  • Agile Bipedal Locomotion via Hierarchical Control by Incorporating Physical Principles, Learning, and Optimization

    Creator:
    Green, Kevin
    Abstract:
    Robotic Bipedal locomotion holds the potential for efficient, robust traversal of difficult terrain. The difficulty lies in the dynamics of locomotion which complicate control and motion planning. Bipedal locomotion dynamics are dimensionally large problems, extremely nonlinear, and operate on the limits of actuator capabilities, which limit the performance of generic...
