Epistemic Learning from Imprecise Annotation

This work introduces epistemic learning from credal supervision, a framework that uses convex sets of plausible labelling distributions as supervision and learns sets of predictive distributions, and shows how credal labels can be obtained through a simple relaxation of existing probabilistic labels, reducing commitmen...

QuadraSHAP: $\epsilon$-Exact Shapley Values for Product Games in Logarithmic Parallel Time

QuadraSHAP is introduced, a method for $\epsilon$-exact Shapley computation in product games, cooperative games whose coalition values factorize across players, and extends to weighted sums of product games, supporting baseline and empirical interventional attribution across a broad class of models.
