Maximum likelihood estimation for the -exponential family
Xiwei Tian, Ting-Kam Leonard Wong, Jiaowen Yang +1
The -exponential family generalizes the standard exponential family via a generalized convex duality motivated by optimal transport. It is the constant-curvature analogue of the…

Logarithmic divergences: geometry and interpretation of curvature
Ting-Kam Leonard Wong, Jiaowen Yang
We study the logarithmic -divergence which extrapolates the Bregman divergence and corresponds to solutions to novel optimal transport problems. We show that this logarith…
