Abstract

Systems and methods to compress MQDF data are disclosed herein. A plurality of eigenvectors is identified. Each eigenvector in the plurality of eigenvectors can correspond to a pattern to be recognized. Each eigenvector in the plurality of eigenvectors can be split into sub-vectors. The sub-vectors can then be grouped into one or more groups according to a location of the sub-vectors within each of the eigenvectors. Each group can be associated with location data of the sub-vectors in the group. At least one group can be compressed according to a codebook. The codebook can be identifiable via the location data.
