  • single Instance Storage in windows 2000
    Conference on USENIX Windows Systems Symposium, 2000
    Co-Authors: William J Bolosky, Scott Corbin, David Allen Goebel, John R Douceur
    Abstract:

    Certain applications, such as Windows 2000's Remote Install service, can result in a set of files in which many different files have the same content. Using a traditional file system to store these files separately results in excessive use of disk and main memory file cache space. Using hard or symbolic links would eliminate the excess resource requirements, but changes the semantics of having separate files, in that updates to one "copy" of a file would be visible to users of another "copy." We describe the Single Instance Store (SIS), a component within Windows® 2000 that implements links with the semantics of copies for files stored on a Windows 2000 NTFS volume. SIS uses copy-on-close to implements the copy semantics of its links. SIS is structured as a file system filter driver that implements links and a user level service that detects duplicate files and reports them to the filter for conversion into links. Because SIS links are semantically identical to separate files, SIS creates them automatically when it detects files with duplicate contents. This paper describes the design and implementation of SIS in detail, briefly presents measurements of a remote install server showing a 58% disk space savings by using SIS, and discusses other possible uses of SIS.

  • an efficient Instance selection algorithm for k nearest neighbor regression
    Neurocomputing, 2017
    Co-Authors: Yunsheng Song, Jiye Liang, Xingwang Zhao
    Abstract:

    The k-Nearest Neighbor algorithm(kNN) is an algorithm that is very simple to understand for classification or regression. It is also a lazy algorithm that does not use the training data points to do any generalization, in other words, it keeps all the training data during the testing phase. Thus, the population size becomes a major concern for kNN, since large population size may result in slow execution speed and large memory requirements. To solve this problem, many efforts have been devoted, but mainly focused on kNN classification. And now we propose an algorithm to decrease the size of the training set for kNN regression(DISKR). In this algorithm, we firstly remove the outlier Instances that impact the performance of regressor, and then sorts the left Instances by the difference on output among Instances and their nearest neighbors. Finally, the left Instances with little contribution measured by the training error are successively deleted following the rule. The proposed algorithm is compared with five state-of-the-art algorithms on 19 datasets, and experiment results show it could get the similar prediction ability but have the lowest Instance Storage ratio.
