ing social networks  and cardiogenic heart failure . A continuous time Bayesian network (CTBN) is a graphical mod-el whose nodes are associated with random variables and whose state evolves continuously over time. As a consequence the evolu-tion of each variable depends on the state of its parents in the graph.

A continuous time Bayesian network model for cardiogenic heart failure E. Gatti D. Luciani F. Stella Published online: 8 December 2011 Springer Science+Business Media, LLC 2011 Abstract Continuous time Bayesian networks are used to diagnose cardiogenic heart failure and to anticipate its likely evolution. The proposed model overcomes

The continuous time Bayesian network (CTBN) is a probabilistic graphical model that enables reasoning about complex, interdependent, and continuous-time subsystems. The model uses nodes to denote subsystems and arcs to denote conditional

Sensitivity Analysis of Continuous Time Bayesian Network
Formally, a continuous time Bayesian network Cover X consists of two components. The ﬁrst is an initial distribution denoted P0 X over X, which can be speciﬁed as a Bayesian network B. This distribution P0 X is used for determining the probability distributions for the initial states of the process. The second is a continuous-time

Evidence at the initial time (t= 0) is incorporated by setting evidence in Band performing Bayesian network inference. The continuous-time transition

types of shock: septic and cardiogenic. Septic shock is the most common, and it is caused by infection. The second most frequent form of shock is the cardiogenic shock and it is a result of a heart failure. The multiscale nature of the ShockOmics database allows to search for attributes that are related to mortality induced by these two types
Learning Parameters of Hybrid Time Bayesian Networks
Example 1 Consider the clinical condition of heart failure (Gatti et al., 2012). Heart failure is said to be cardiogenic when the cardiac muscle is the organ from which the circulatory failure is triggered. The strength of the heart muscle is represented by its pump (PP). Cardiogenic heart failure may be caused by acute myocardial infarction (AMI).
Using Continuous-Time Bayesian Networks for Standards-Based
Let X be a set of continuous-time Markov processes, X 1;:::;X n, each of which can take on a discrete set of values. A continuous time Bayesian network, N, over X consists of two components. First, an initial distribution P0 X, which can be speciﬁed as a Bayesian network Bover X. Second, a continuous transition model, speciﬁed as a directed

The selection for variables for the multivariate Cox proportional hazards models was conducted using the Bayesian model averaging (BMA) method [8,9].
