چکیده

Probabilistic logical models have proven to be very successful at modelling uncertain, complex relational data. Most current formalisms and implementations focus on modelling domains that only have discrete variables. Yet many real-world problems are hybrid and have both discrete and continuous variables. In this paper we focus on the Logical Bayesian Network (LBN) formalism. This paper discusses our work in progress in developing hybrid LBNs, which offer support for both discrete and continuous variables. We provide a brief sketch for basic parameter learning and inference algorithms for them.

Learning Directed Probabilistic Logical Models Using Ordering-Search

There is an increasing interest in upgrading Bayesian networks to the relational case, resulting in so-called directed probabilistic logical models. In this paper we discuss how to learn non-recursive directed probabilistic logical models from relational data. This problem has already been tackled before by upgrading the structure-search algorithm for learning Bayesian networks. In this paper w...

Instantiation to Support the Integration of Logical and Probabilistic Knowledge

Integrating the expressive power of first-order logic with the ability of probabilistic reasoning of Bayesian networks has attracted the interest of many researchers for decades. We present an approach to integration that translates logical knowledge into Bayesian networks and uses Bayesian network composition to build a uniform representation that supports both logical and probabilistic reason...

Solving Stochastic Pert Networks Exactly Using Hybrid Bayesian Networks

In this paper, we describe how a stochastic PERT network can be formulated as a Bayesian network. We approximate such PERT Bayesian network by mixtures of Gaussians hybrid Bayesian networks. Since there exists algorithms for solving mixtures of Gaussians hybrid Bayesian networks exactly, we can use these algorithms to make inferences in PERT Bayesian networks.

Construction cost estimation of spherical storage tanks: artificial neural networks and hybrid regression—GA algorithms

One of the most important processes in the early stages of construction projects is to estimate the cost involved. This process involves a wide range of uncertainties, which make it a challenging task. Because of unknown issues, using the experience of the experts or looking for similar cases are the conventional methods to deal with cost estimation. The current study presents data-driven metho...

Target Identification with Dynamic Hybrid Bayesian Networks

The continuous growth of data has created a demand for better data fusion algorithms. In this study we have used a method called Bayesian networks to answer the demand. The reason why Bayesian networks are used in wide range of applications is that modelling with Bayesian networks offers easy and straightforward representation for combining a priori knowledge with the observations. Another reas...
