Patents by Inventor Didier E. Zwierski

Didier E. Zwierski has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 5583951
    Abstract: A method is proposed for determining approximations of eigenvectors of a covariance matrix associated with signal data on the basis of the Principal Component Transform. Successive iterations on estimates enhance the development into the direction of the principal component considered. The method is applicable to the Singular Value Decomposition of data matrices. The operations to be performed are similar to those required in a neural net for adapting the synaptic coefficients, Apparatus are proposed for performing the method.
    Type: Grant
    Filed: August 31, 1994
    Date of Patent: December 10, 1996
    Assignee: U.S. Philips Corporation
    Inventors: Jacques A. Sirat, Didier E. Zwierski
