Description: a fast retrieval algorithm for English texts is proposed. First of all, the English texts are mapped into frequency matrixes of order 26 and the dimensions of texts representation space are reduced through Singular Value Decomposition. Second, it fuses the features of the first singular value component and the second one, and then gets the complex feature vectors which reflect not only the statistic frequency but also the sequential structure of letters.
- [svd] - Based on the SVD algorithm matlab source
- [CLAPACK3-Windows] - LAPACK is written in Fortran90 and provi
