摘要

En 中文
The continuous time Bayesian network (CTBN) is a model capable of describing the probability distribution over a set of variables as it changes in time. The model relies on a directed graph structure to describe direct dependencies between variables, thereby simplifying the underlying parameters that describe the initial distribution and transition behavior. Although this approach can be effective in managing complexity, the size of the model can still be intractable if one variable depends directly on many other variables. To address this issue, we present two methods for imposing additional structure on the model that are capable of capturing regularities in the data that cannot be represented using the CTBN graph structure alone. We demonstrate how these methods can reduce model complexity and compare the representational capabilities of both approaches. (C) 2019 Elsevier Inc. All rights reserved.
