The variants of randomized Kaczmarz (RK) and randomized Gauss-Seidel (RGS) are distinct iterative algorithms for ridge regression. Theoretical convergence rates for these two algorithms were provided by a simple side-by-side analysis in recent work.

An interval Pade-type approximation is introduced and then Routh-Pade-type method (IRPTM) is presented to model reduction in interval systems. The denominator in reduced model is obtained from the stable Routh table, and its numerator is constructed

In this paper, an improved gradient iterative (GI) algorithm for solving the Lyapunov matrix equations is studied. Convergence of the improved method for any initial value is proved with some conditions. Compared with the GI algorithm, the improved a

A new function-valued partial Pade-type approximation was introduced in the polynomial space, and an explicit determinant formula was derived by means of some orthogonal polynomials. This method can be applied to estimating surplus eigenvalues of the

In tins paper, a new event detection pitch detector based on the dyadic wavelet transform was constructed by selecting an optimal scale. The proposed pitch detector is accurate, robust to noise and computationally simple. Experiments show the superio

In this paper, a practical Werner-type continued fraction method for solving matrix valued rational interpolation problem is provided by using a generalized inverse of matrices. In order to reduce the continued fraction form to rational function form

The generalized inverse function-valued Pade approximant was defined to solve the integral equations. However, it is difficult to compute the approximants by some high-order determinant formulas. In this paper, to simplify computation of the function

Based on rational Bezier curves given by Ron Goldman, a new fractional rational Bezier curve was first defined in terms of fractional Bernstein bases. Moreover, some basic properties were dicussed and a theorem connected to Poisson curves was obtaine
