A self-agency bias in preschoolers' causal inferences

Tamar Kushnir, Henry M. Wellman, Susan A. Gelman
2009 Developmental Psychology  
When initial independent effects were probabilistic, and thus subsequent simultaneous actions were causally ambiguous, children showed a self-agency bias.  ...  These results demonstrate that children's own experience of action influences their causal learning, and suggest possible benefits in uncertain and ambiguous everyday learning contexts.  ...  Acknowledgments This research was supported by a fellowship from the McDonnell Collaborative Initiative on Causal Learning and an NICHD post-doctoral fellowship to T.K.  ...

Comment On Hausman & Woodward On The Causal Markov Condition

Daniel Steel
2006 British Journal for the Philosophy of Science  
Hausman & Woodward present an argument for the Causal Markov Condition (CMC) on the basis of a principle they dub "modularity" ([1999, 2004]).  ...  In addition, I show that their argument is invalid and trace this invalidity to two features of modularity, namely, that it is stated in terms of pairwise independence and "arrowbreaking" interventions  ...  Acknowledgments I would like to thank Dan Hausman for gracious, in depth correspondence regarding an earlier draft of this essay and two anonymous referees for helpful comments.  ...

Experiences with Modelling Issues in Building Probabilistic Networks [chapter]

Linda C. van der Gaag, Eveline M. Helsper
2002 Lecture Notes in Computer Science  
Since many of these issues pertain not only to our application but are likely to emerge for other applications as well, we feel that sharing them will contribute to engineering probabilistic networks in  ...  As we have developed a large probabilistic network for a complex medical domain, we have encountered and resolved numerous non-trivial modelling issues.  ...  We are grateful to Babs Taal and Berthe Aleman from the Netherlands Cancer Institute, Antoni van Leeuwenhoekhuis, who provided the domain knowledge for the construction of the oesophagus network.  ...

A diagnostic method that uses causal knowledge and linear programming in the application of Bayes' formula

Gregory F. Cooper
1986 Computer Methods and Programs in Biomedicine  
This paper discusses a method for using causal knowledge to structure findings according to their probabilistic dependencies.  ...  One assumption that is often made in the application of the formula is that the findings in a case are conditionally independent.  ...  A fundamentally important aspect of a causal representation is that it can greatly limit the number of possible probabilistic influences on any process or state.  ...

Probabilistic causal models of multimorbidity concepts

Martijn Lappenschaar, Arjen Hommersom, Peter J F Lucas
2012 AMIA Annual Symposium Proceedings  
In this paper, we employ causal Bayesian networks to define and analyze a novel framework that can be used to model a spectrum of aspects related to multimorbidity.  ...  ., the presence of multiple diseases within one person, is a significant health-care problem for western societies: diagnosis, prognosis and treatment in the presence of of multiple diseases can be complex  ...  Concretely, if we have an arc C → E, then we say C causally positively influences E if: P (e | do(c)) > P (e | do(c)) Negative causal influences can be defined similarly.  ...

Causal Graphs and Biological Mechanisms [chapter]

Alexander Gebharter, Marie I. Kaiser
2013 Explanation in the Special Sciences  
In this paper we argue that the formal framework of causal graph theory is well-suited to provide us with models of biological mechanisms that incorporate quantitative and probabilistic information.  ...  Although this adequately characterizes how mechanisms are represented in biology textbooks, contemporary biological research practice shows the need for quantitative, probabilistic models of mechanisms  ...  Acknowledgements We would like to thank the members of the research group "Causation and Explanation", the participants of the colloquia at the University of Cologne and at the University of Düsseldorf  ...

A Backwards View for Assessment [article]

Ross D. Shachter, David Heckerman
2013 arXiv   pre-print
Much artificial intelligence research focuses on the problem of deducing the validity of unobservable propositions or hypotheses from observable evidence.!  ...  Many of the knowledge representation techniques designed for this problem encode the relationship between evidence and hypothesis in a directed manner.  ...  This type of conditional independence is an important simplifying assumption for the construction and assessment of models of uncertainty. , /"'""' • � , In the influence diagram we always require that  ...

Causality and Unification: How Causality Unifies Statistical Regularities

Gerhard Schurz
2015 THEORIA : an International Journal for Theory, History and Fundations of Science  
It is demonstrated that not the core of TC but extended versions of TC have empirical content, by means of which they can generate independently testable predictions.  ...  The core axioms of the theory of causal nets (TC) are justified because they give the best if not the only unifying explanation of two statistical phenomena: screening off and linking up.  ...  Acknowledgements This work has been supported by the CRC 991 of the DFG.  ...

A Dynamic Interaction Between Machine Learning and the Philosophy of Science

Jon Williamson
2004 Minds and Machines  
I discuss the nature of this interaction and give a case study highlighting interactions between research on Bayesian networks in machine learning and research on causality and probability in the philosophy  ...  of science.  ...  The causal Markov condition says that a cause is probabilistically independent of any of its noneffects conditional on its direct causes.  ...

Qualitative Propagation and Scenario-based Explanation of Probabilistic Reasoning [article]

Max Henrion, Marek J. Druzdzel
2013 arXiv   pre-print
Comparing a few of the most probable scenarios provides an approximate way to explain the results of probabilistic reasoning. Both schemes employ causal as well as probabilistic knowledge.  ...  The other, Scenario-based reasoning, involves the generation of alternative causal "stories" accounting for the evidence.  ...  The condition it embodies is sometimes called causal independence, namely that the probability that each present cause is sufficient to produce the effect is independent of the presence or sufficiency  ...

Bayesian network modelling through qualitative patterns

Peter J.F. Lucas
2005 Artificial Intelligence  
In the paper, we deploy both causal independence and QPNs in developing and analysing a collection of qualitative, causal interaction patterns, called QC patterns.  ...  A notion that has been suggested in the literature to facilitate Bayesian-network development is causal independence.  ...  Preliminaries To start, the basic theory of Bayesian networks, causal independence and qualitative probabilistic networks are reviewed.  ...
