First-Order Extension of the FLP Stable Model
... 1 (u, v, w)) can be equivalently rewritten without second-order variables as ¬(p ↔ q) ∧ (r ↔ p ∨ q). Though rule arrows (←) are treated like usual implications in the FOL-representation of Π, they are distinguished in the definition of Π4 (u) because of the presence of ’B∧’ in (7). If we modify Π4 ( ...

Recognizing solid objects by alignment with an image
... point, for m model points and n image points there are (~)(~)3! possible different alignments, resulting from pairing each triple of model points with each triple of image points. Thus for point features the worst-case number of hypotheses is O(m3n3). The implementation that we describe below relies ...

I We show that the IAMB algorithm [3] for Markov Blanket discovery also optimises this model, using a sparsity prior. I Finally we extend IAMB to include a domain ...
