Incorporating Unlabeled Data into Distributionally Robust Learning

no code implementations16 Dec 2019 Charlie Frogner, Sebastian Claici, Edward Chien, Justin Solomon

We examine the performance of this new formulation on 14 real datasets and find that it often yields effective classifiers with nontrivial performance guarantees in situations where conventional DRL produces neither.

Learning Embeddings into Entropic Wasserstein Spaces

2 code implementations8 May 2019 Charlie Frogner, Farzaneh Mirzazadeh, Justin Solomon

Euclidean embeddings of data are fundamentally limited in their ability to capture latent semantic structures, which need not conform to Euclidean spatial assumptions.

Learning Entropic Wasserstein Embeddings

no code implementations ICLR 2019 Charlie Frogner, Farzaneh Mirzazadeh, Justin Solomon

Despite their prevalence, Euclidean embeddings of data are fundamentally limited in their ability to capture latent semantic structures, which need not conform to Euclidean spatial assumptions.

Approximate inference with Wasserstein gradient flows

no code implementations12 Jun 2018 Charlie Frogner, Tomaso Poggio

We present a novel approximate inference method for diffusion processes, based on the Wasserstein gradient flow formulation of the diffusion.
