An Independence of Causal Interactions Model for Opposing Inuences
Paul P. Maaskant, Marek J. Drużdżel · 2008
We introduce the DeMorgan gate, an Independence of Causal Interactions (ICI) model that is capable of modeling opposing inuences, i.e., a mixture of positive and negative inuences of parents on a child. The model is a noisy version of a conjunctive normal form of Boolean functions and is an extension and a combination of the popular NoisyOR and Noisy-AND models, preserving their intuitive semantics. We report the results of a simple experiment testing the usefulness of the proposed model for elicitation of conditional probability distributions.
