A metric between probability distributions on finite sets of different cardinalities and applications to order reduction

M Vidyasagar - IEEE Transactions on Automatic Control, 2012 - ieeexplore.ieee.org
In this paper we define a metric distance between probability distributions on two distinct
finite sets of possibly different cardinalities. The metric is defined in terms of a joint …

Model reduction of Markov chains via low-rank approximation

K Deng, D Huang - 2012 American Control Conference (ACC), 2012 - ieeexplore.ieee.org
