Tighter Variational Representations of f-Divergences via Restriction to Probability Measures
Avraham Ruderman, Mark Reid, Dario Garcia-Garcia +1
We show that the variational representations for f-divergences currently used in the literature can be tightened. This has implications to a number of methods recently proposed bas…
The Convexity and Design of Composite Multiclass Losses
Mark Reid, Robert Williamson, Peng Sun
We consider composite loss functions for multiclass prediction comprising a proper (i.e., Fisher-consistent) loss over probability distributions and an inverse link function. We es…
Crowd & Prejudice: An Impossibility Theorem for Crowd Labelling without a Gold Standard
Nicolás Della Penna, Mark D. Reid
A common use of crowd sourcing is to obtain labels for a dataset. Several algorithms have been proposed to identify uninformative members of the crowd so that their labels can be d…
