First-Order Bayes-Ball

چکیده
Efficient probabilistic inference is key to the success of statistical relational learning. One issue that increases the cost of inference is the presence of irrelevant random variables. The Bayes-ball algorithm can identify the requisite variables in a propositional Bayesian network and thus ignore irrelevant variables. This paper presents a lifted version of Bayes-ball, which works directly on the first-order level, and shows how this algorithm applies to (lifted) inference in directed first-order probabilistic models.

Adaptation to Embodied Dynamics: Evidence from Bayes’ Ball
In recent years researchers have begun to recognize the remarkable intelligence of even routine interactive behavior— the extent to which humans adapt to and exploit the low-level dynamics of cognitive processes, perception, and motor control without conscious deliberation. We developed an experiment known as Bayes’ Ball, in which subjects must estimate short time intervals (< 1000 ms) in order...

متن کاملA New Algorithm for Generating Situation-Specific Bayesian Networks Using Bayes-Ball Method
Multi-Entity Bayesian Network (MEBN) is an expressive first-order probabilistic logic that represents the domain using parameterized fragments of Bayesian networks. Probabilistic-OWL (PR-OWL) uses MEBN to add uncertainty support to OWL, the main language of the Semantic Web. The reasoning in MEBN is made by the construction of a Situation-Specific Bayesian Network (SSBN), a minimal Bayesian net...

Description R package for design of experiments for association studies for detection of linkage disequilibrium. Uses an existing deterministic power calculation for detection of linkage disequilibrium between a bi-allelic QTL and a bi-allelic marker, together with the Spiegelhalter and Smith Bayes factor to generate designs with power to detect effects with a given Bayes factor.
متن کاملInvestigating the Dynamics of a Ball-Spring Autobalancer in a Rotor with Non-Linear Bearings
Although the traditional automatic ball balancer (ABB) has numerous advantages, it has two major deficiencies, i.e., it has a limited balance stable region and it increases the vibration amplitude of the rotor at transient state. These deficiencies limit the applicability of ABBs. In this regard, a new type of ABB called “the Ball-spring autobalancer” has been proposed to resolve the mentioned ...
