Abstract: This talk discusses a Bayesian network, a probability distribution factorized along on a diamond DAG (four nodes). At the highest layer we use noisy Boolean functions (of two variables). When the Fourier series of these noisy Boolean functions are used in the algorithm for counterfactuals (Pearl) we obtain easy explicit formulae for computing counterfactual probabilities.

Causality and causal inference have been/are of interest, e.g., for cognitive science, genetic epidemiology, philosophy and AI. Philosophers have discussed the general nature of (probabilistic) causality. At the end of this talk one definition of a probabilistic cause is applied on the counterfactual probabilities of the diamond DAG.
