Nonuniform sampling has many applications in signal processing. Explicit form expression is derived for nonuniform discrete Fourier transform (NDFT) in this paper. Numerical results verify its correctness. The proposed result provides an accurate form solution of the problem for the first time.
In this paper a simple infinity norm based neural network algorithm for estimation of the principal component is developed. It seems to be especially useful in applications with changing environment, where the learning process has to be repeated in online manner. Theoretical analysis shows the weight vector converges to the principal eigenvector asymptotically. In comparison with the existing algorithms,...
