Existence of Stein kernels under a spectral gap, and discrepancy bounds
TA Courtade, M Fathi, A Pananjady - 2019 - projecteuclid.org
We establish existence of Stein kernels for probability measures on $\mathbb{R}^{d}$ satisfying
a Poincaré inequality, and obtain bounds on the Stein discrepancy of such measures. …

Justification of logarithmic loss via the benefit of side information
We consider a natural measure of relevance: the reduction in optimal prediction risk in the
presence of side information. For any given loss function, this relevance measure captures the …
