In this paper we address the problem of understanding the success of algorithms that organize patches according to graph-based metrics. Algorithms that analyze patches extracted from images or time se...
A relation between dimension of the harmonic measure，entropy and drift for a random walk on a hyperbolic space
harmonic measure entropy drift hyperbolic space
2009/3/19
We establish in this paper an exact formula which links the dimension of the harmonic measure, the asymptotic entropy and the rate of escape for a random walk on a discrete subgroup of the isometry gr...
