Hwang, Chii-Ruey
Retired Research Fellow
Dr. Hwang's research interest is Probability theory. He investigates stochastic system with Markovian structure or arisen from real life applications. Accelerating convergence of Markov processes by anti-symmetric perturbations to a common underlying equilibrium, variance reduction in calculation of expectations, optimal updating schemes are among the main topics. The analysis of the spectral gap of anti-symmetric perturbations of Laplacian and a probabilistic approach for
the convergence rate of non-reversible processes are some of the related problems. The empirical invariances from the stock market as well as the corresponding stochastic structures are also his interests.
