Title:
DATA INDEX DIMENSION REDUCTION METHOD, AND DATA SEARCH METHOD AND DEVICE USING SAME
Document Type and Number:
WIPO Patent Application WO/2011/155288
Kind Code:
A1
Abstract:
Disclosed is a new method of reducing indices of feature quantities to be compared, comprising the steps of deriving a Gaussian kernel matrix for a first index corresponding to a feature quantity for standardization that is included in a standard database; normalizing the Gaussian kernel matrix; deriving an anisotropic transition kernel matrix from the normalized Gaussian kernel matrix; and deriving a transformation matrix (F) from an eigenvalue problem of the anisotropic transition kernel matrix.
