Learning Bayesian Networks with Restricted Causal Interactions [article]

Julian R. Neil, Chris S. Wallace, Kevin B. Korb
2013 arXiv   pre-print
We describe an alternative interpretation, and use a Minimum Message Length (MML) (Wallace, 1987) metric for structure learning of networks exhibiting causal independence, which we term first-order networks  ...  While log-linear models in this context are not new (Whittaker, 1990; Buntine, 1991; Neal, 1992; Heckerman and Meek, 1997), for structure learning they are generally subsumed under a naive Bayes model.  ...  We also tracked a discrepancy in the posterior estimates of the FON and dual network to a difference in parameter prior and estimation, which we intend to address in further work.  ...

Seeing Versus Doing: Two Modes of Accessing Causal Knowledge

Michael R. Waldmann, York Hagmayer
2005 Journal of Experimental Psychology. Learning, Memory and Cognition  
The predictions reflect sensitivity both to the structure of the causal models and to the size of their parameters.  ...  We present four learning experiments with deterministic and probabilistic data showing that people indeed make different predictions from causal models, whose parameters were learned in a purely observational  ...  In this sense, causal-model theory is primarily a parameter estimation learning theory.  ...

Playing against Nature: causal discovery for decision making under uncertainty [article]

M. Gonzalez-Soto, L.E. Sucar, H.J. Escalante
2018 arXiv   pre-print
We show that the model achieves a performance similar to the classic Q-learning while it also acquires a causal model of the environment.  ...  As proof of concept, we present an implementation of this causal decision making model and apply it in a simple scenario.  ...  We are grateful to the National Institute of Astrophysics Optics and Electronics (INAOE) and to Mrs. Graciela Soto for their generous funding in order to attend ICML 2018.  ...

Observing and Intervening: Rational and Heuristic Models of Causal Decision Making

Bjorn Meder, Tobias Gerstenberg, York Hagmayer, Michael R. Waldmann
2010 Open Psychology Journal  
A Bayesian approach of rational causal inference, which aims to infer the structure and its parameters from the available data, provides the benchmark model.  ...  Recently, a number of rational theories have been put forward which provide a coherent formal framework for modeling different types of causal inferences, such as prediction, diagnosis, and action planning  ...  Within the causal Bayes nets framework, a variety of learning algorithms have been developed to infer causal structures and parameter values [12] .  ...

Causal Discovery in Physical Systems from Videos [article]

Yunzhu Li, Antonio Torralba, Animashree Anandkumar, Dieter Fox, Animesh Garg
2020 arXiv   pre-print
The causal structure assumed by the model also allows it to make counterfactual predictions and extrapolate to systems of unseen interaction graphs or graphs of various sizes.  ...  In particular, our goal is to discover the structural dependencies among environmental and object variables: inferring the type and strength of interactions that have a causal effect on the behavior of  ...  This entails jointly performing model class estimation, parameter inference and thereby building a predictive model for new latent structures at test time in a meta-learning framework.  ...
