  • Because exact inference in Bayesian networks is known to be extraordinarily inefficient (in the worst case NP-hard), U-DIRECTOR exploits recent advances in approximate Bayesian inference via stochastic sampling. The accuracy of these methods depends on the number of samples used. Moreover, stochastic sampling methods typically have an “anytime” property which is particularly attractive for real-time applications. … a performance analysis was conducted to measure the network update time using an exact Bayesian inference algorithm (Clustering [17]) and two approximate Bayesian inference algorithms (EPIS-BN [36] and Likelihood weighting [31]).
