sparse approximationの例文

• He is known for work on sparse approximation, numerical linear algebra, and random matrix theory.
• The problem of finding an optimal sparse coding R with a given dictionary \ mathbf { D } is known as sparse approximation ( or sometimes just sparse coding problem ).
• Shearlets are to date the only directional representation system which provides sparse approximation of anisotropic features while providing a unified treatment of the continuum and digital realm in the sense of allowing faithful implementation.
• He made contributions in the areas of optimal filter banks, nonlinear phase extensions of discrete Walsh-Hadamard transform and discrete Fourier transform, principal component analysis of first-order autoregressive process, sparse approximation, financial signal processing and quantitative finance.
