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…
Conditional Random Fields and Support Vector Machines: A Hybrid Approach
Qinfeng Shi, Mark D. Reid, Tiberio Caetano
We propose a novel hybrid loss for multiclass and structured prediction problems that is a convex combination of log loss for Conditional Random Fields (CRFs) and a multiclass hing…
