A note about redundancy in influence diagrams

Enrico Fagiuoli, Marco Zaffalon
1998 International Journal of Approximate Reasoning  
In this note, we initially observe that an influence diagram can have some arcs that are not necessary for a complete description of the model.  ...  Furthermore, it allows a redundant influence diagram to be transformed into another ID, that can be used to compute the optimal policy in an equivalent but more efficient way. /E  ...  ., 1 we define the set FDi = (t E Tt(Di) t _k v in Gi~, A redundant influence diagram.  ...

Human-Robot Analogy − How Physiology Shapes Human and Robot Motion

Veljko Potkonjak, Vladimir Petrović, Kosta Jovanović, Dragan Kostić
2013 Advances in Artificial Life, ECAL 2013  
One notes that humans do not resolve the redundancy on the level of consciousness, except in some specific examples (like obstacle avoidance), but rather on a lower level of decision-making -the human  ...  This tendency increases interest in human-robot analogy, and the present work is a part of this stream.  ...  Note that capabilities of the kinematic redundancy will be utilized only -actuator redundancy is out of scope of this paper.  ...

Assurance of complex pressure control system operability in high-temperature media

K S Terasmes, E A Petrovsky, K A Bashmur, S V Tynchenko, V V Bukhtoyarov, N A Shepeta
2019 Journal of Physics, Conference Series  
The authors considered the ways for improving reliability of pressure control systems operated in severe conditions by redundancy of the sensing element of the valve with a system equipped with a metal  ...  For the purpose of control and overpressure protection in pipeline systems of power industry and pressure vessels, indirect-action valves consisting of a main valve and a pilot valve are often used.  ...  PV faults in a result of breakage of a spring-type sensing element amount to about 3% and are distributed among several items of the diagram.  ...

Quantifying Redundant Information in Predicting a Target Random Variable [article]

Virgil Griffith, Tracey Ho
2015 arXiv   pre-print
This paper considers the problem of defining a measure of redundant information that quantifies how much common information two or more random variables specify about a target random variable.  ...  We discussed desired properties of such a measure, and propose new measures with some desirable properties.  ...  For example, in the PI-diagram for n = 2 (Figure 1): {1} denotes the unique information about Y that only X 1 carries (likewise {2} denotes the information only X 2 carries); {1, 2} denotes the redundant  ...

Nonnegative Decomposition of Multivariate Information [article]

Paul L. Williams, Randall D. Beer
2010 arXiv   pre-print
Finally, we use this redundancy lattice to propose a definition of partial information atoms that exhaustively decompose the Shannon information in a multivariate system in terms of the redundancy between  ...  We begin with a new definition of redundancy as the minimum information that any source provides about each possible outcome of the variable, averaged over all possible outcomes.  ...  Beggs, A.

Efficient State-Diagram Construction Methods for Software Pipelining [chapter]

Chihong Zhang, Ramaswamy Govindarajan, Sean Ryan, Guang R. Gao
1999 Lecture Notes in Computer Science  
The heuristic method uses a surprisingly simple check which is formally shown to completely eliminate redundancy in the state diagram.  ...  The second method is a heuristic approach which exploits the structure of state diagram construction to eliminate redundancy at the earliest opportunity in an aggressive fashion.  ...  In Section 5 we study empirically how many non-redundant paths does RP miss in the state diagram and whether they have any influence on the constructed software pipelined schedule.  ...

What Causally Insensitive Events Tell us About Overdetermination

Sara Bernstein
2014 Philosophia  
The normal procedure for classifying a case of redundant causation involves looking to see which processes "run to completion". 10 Consider the following case: Diagram 2: Early Preemption In this diagram  ...  But note that the law at work in a case of trumping is an unconvincing stand-in for a natural law or laws. No natural law decides, ex post facto, which physical process is the cause of an outcome.  ...
