Piecewise Linear Approximations of Nonlinear Deterministic Conditionals in Continuous Bayesian Networks
نویسندگان
چکیده
To enable inference in continuous Bayesian networks containing nonlinear deterministic conditional distributions, Cobb and Shenoy (2005) have proposed approximating nonlinear deterministic functions by piecewise linear ones. In this paper, we describe two principles and a heuristic for finding piecewise linear approximations of nonlinear functions. We illustrate our approach for some commonly used oneand two-dimensional nonlinear deterministic functions.

Inference in Hybrid Bayesian Networks with Nonlinear Deterministic Conditionals
To enable inference in hybrid Bayesian networks containing nonlinear deterministic conditional distributions using mixtures of polynomials or mixtures of truncated exponentials, Cobb and Shenoy in 2005 propose approximating nonlinear deterministic functions by piecewise linear ones. In this paper, we describe a method for finding piecewise linear approximations of nonlinear functions based on t...
متن کاملModeling Nonlinear Deterministic Relationships in Bayesian Networks
In a Bayesian network with continuous variables containing a variable(s) that is a conditionally deterministic function of its continuous parents, the joint density function for the variables in the network does not exist. Conditional linear Gaussian distributions can handle such cases when the deterministic function is linear and the continuous variables have a multi-variate normal distributio...

متن کاملMixtures of Polynomials in Hybrid Bayesian Networks with Deterministic Variables
The main goal of this paper is to describe inference in hybrid Bayesian networks (BNs) using mixtures of polynomials (MOP) approximations of probability density functions (PDFs). Hybrid BNs contain a mix of discrete, continuous, and conditionally deterministic random variables. The conditionals for continuous variables are typically described by conditional PDFs. A major hurdle in making infere...
