Deterministic or stochastic trend
Web1 day ago · In particular, when fitting deterministic models to estimate the rate of spread, we do not account for the stochastic nature of epidemics and that, given the same system, some outbreaks may lead to epidemics and some may not. Typically, an observed epidemic that we wish to control is a major outbreak. WebMar 29, 2024 · In this article, we provide new practical and theoretical developments for the landing algorithm. First, the method is extended to the Stiefel manifold, the set of rectangular orthogonal matrices. We also consider stochastic and variance reduction algorithms when the cost function is an average of many functions.

The reader is referred to the classical work by Stanley and Kato [25] for a full description of the method. In the following, a two-scale formulation is proposed and justified. Finally, the stochastic element in introduced to the ...
