  • Method, electronic device and storage medium for data projection
    Patent number: 11853387
    Abstract: A data sparse projection method, includes: randomly initializing a high-dimensional sparse two-dimensional matrix (S1); fixing the high-dimensional sparse two-dimensional matrix, and calculating an optimal output variable by using the high-dimensional sparse two-dimensional matrix (S2); fixing the optimal output variable, and calculating an optimal high-dimensional sparse two-dimensional matrix by using the optimal output variable (S3); and cyclically fixing the high-dimensional sparse two-dimensional matrix and the output variable until the optimal output variable is no longer increased when the high-dimensional sparse two-dimensional matrix is fixed (S4).
