Superfast 1-Norm Estimation
Soo Go, Victor Y. Pan
A matrix algorithm is said to be superfast (that is, runs at sublinear cost) if it involves much fewer scalars and flops than the input matrix has entries. Such algorithms have bee…

Robust Parameter Estimation for Rational Ordinary Differential Equations
Oren Bassik, Yosef Berman, Soo Go +6
We present a new approach for estimating parameters in rational ODE models from given (measured) time series data. In typical existing approaches, an initial guess for the paramete…

Fast Approximation of Polynomial Zeros and Matrix Eigenvalues
Victor Y. Pan, Soo Go, Qi Luan +1
We approximate the d complex zeros of a univariate polynomial p(x) of a degree d or those zeros that lie in a fixed region of interest on the complex plane such as a disc or a squa…
