  • Cluster ensembles for high dimensional clustering : an empirical study

    Creator:
    Oregon State University. Dept. of Computer Science, Fern, Xiaoli Z., and Brodley, Carla E.
    Abstract:
    This paper studies cluster ensembles for high dimensional data clustering. We examine three different approaches to constructing cluster ensembles. To address high dimensionality, we focus on ensemble construction methods that build on two popular dimension reduction techniques, random projection and principal component analysis (PCA). We present evidence showing that ensembles...

  • Test case prioritization

    Creator:
    Malishevsky, Alexey Grigorievich
    Abstract:
    Regression testing is an expensive software engineering activity intended to provide confidence that modifications to a software system have not introduced faults. Test case prioritization techniques help to reduce regression testing cost by ordering test cases in a way that better achieves testing objectives. In this thesis, we are interested...

  • Base inclinations in natural and synthetic DNAs

    Creator:
    Chou, Ping-Jung
    Abstract:
    A sophisticated computer program is developed to analyze flow linear dichroism data on nucleic acids for individual base inclinations. Measured absorption and linear dichroism data for synthetic AT and GC polymers and natural DNAs are analyzed. The reliability of the program is tested on data for the synthetic polymers, and...

  • Assessing the need for transformation of response variables

    Creator:
    Oregon State University. Forest Research Laboratory, Sabin, Thomas E., and Stafford, Susan G.
    Abstract:
    Violations of one or more of the assumptions made In analysis of variance (ANOVA) or linear regression analysis may lead to erroneous results. Often data will not conform to the assumptions implicit in the analyses, but transforming the data to a different scale may lead to an appropriate model. Before...

  • A graphic user interface for monophonic music analysis

    Creator:
    Matos G., Soraya J.
    Abstract:
    A Graphic User Interface is developed to determine the existence of a particular sequence of piano notes within a monophonic sound waveform. Such waveforms are recorded within the Graphic User Interface and then passed to the monophonic analysis engine. The first phase of analysis segments the PCM sound data to...

  • Solving polynomial equations from 2000 B.C. through 20th century

    Creator:
    Farea, Hussain A.
    Abstract:
    This paper is divided into two parts. The first part traces (in details providing proofs and examples) the history of the solutions of polynomial equations(of the first, second, third, and fourth degree) by radicals from Babylonian times (2000 B.C.) through 20th century. Also it is shown that there is no...
