Where We Stand at Probabilistic Reasoning

چکیده
Bayes-Nets are a suitable means for probabilistic inference. Such nets are very restricted concerning the communication language with the user, however. MinREnt-inference in a conditional environment is a powerful counterpart to this concept. Here conditional expressions of high complexity instead of mere potential tables in a directed acyclic graph, permit rich communication between system and user. This is true as well for knowledge acquisition as for query and response. For any such step of probabilistic reasoning, processed information is measurable in the information theoretical unit [bit]. The expert-system-shell SPIRIT is a professional tool for such inference and allows realworld (decision-)models with umpteen variables and hundreds

Load-Frequency Control: a GA based Bayesian Networks Multi-agent System
Bayesian Networks (BN) provides a robust probabilistic method of reasoning under uncertainty. They have been successfully applied in a variety of real-world tasks but they have received little attention in the area of load-frequency control (LFC). In practice, LFC systems use proportional-integral controllers. However since these controllers are designed using a linear model, the nonlinearities...
متن کاملA COMMON FRAMEWORK FOR LATTICE-VALUED, PROBABILISTIC AND APPROACH UNIFORM (CONVERGENCE) SPACES
We develop a general framework for various lattice-valued, probabilistic and approach uniform convergence spaces. To this end, we use the concept of $s$-stratified $LM$-filter, where $L$ and $M$ are suitable frames. A stratified $LMN$-uniform convergence tower is then a family of structures indexed by a quantale $N$. For different choices of $L,M$ and $N$ we obtain the lattice-valued, probabili...
متن کاملEvidence - based CAM: Where does it stand?
In the past 10 years evidence - based medicine (EBM) has developed well in all aspects of allopathic medicine giving a new dimension to patient care including cost reduction and attention to medical ethics. With the public and medical community return to complementary and alternative medicine (CAM) in the last two decades there has been a call for evidence - based CAM … in the same way that all...
متن کاملReasoning Algebraically About Probabilistic Loops
Back and von Wright have developed algebraic laws for reasoning about loops in the refinement calculus. We extend their work to reasoning about probabilistic loops in the probabilistic refinement calculus. We apply our algebraic reasoning to derive transformation rules for probabilistic action systems. In particular we focus on developing data refinement rules for probabilistic action systems. ...
