Scalable Unbalanced Sobolev Transport for Measures on a Graph

Tam Le, Truyen Nguyen, Kenji Fukumizu

Optimal transport (OT) is a popular and powerful tool for comparing probability measures. However, OT suffers a few drawbacks: (i) input measures required to have the same mass, (i…

Dynamic Flows on Curved Space Generated by Labeled Data

Xinru Hua, Truyen Nguyen, Tam Le +2

The scarcity of labeled data is a long-standing challenge for many machine learning tasks. We propose our gradient flow method to leverage the existing dataset (i.e., source) to ge…

Sobolev Transport: A Scalable Metric for Probability Measures with Graph Metrics

Tam Le, Truyen Nguyen, Dinh Phung +1

Optimal transport (OT) is a popular measure to compare probability distributions. However, OT suffers a few drawbacks such as (i) a high complexity for computation, (ii) indefinite…

Adversarial Regression with Doubly Non-negative Weighting Matrices

Tam Le, Truyen Nguyen, Makoto Yamada +2

Many machine learning tasks that involve predicting an output response can be solved by training a weighted regression model. Unfortunately, the predictive power of this type of mo…

Entropy Partial Transport with Tree Metrics: Theory and Practice

Tam Le, Truyen Nguyen

Optimal transport (OT) theory provides powerful tools to compare probability measures. However, OT is limited to nonnegative measures having the same mass, and suffers serious draw…

On the Convergence of Gradient Descent in GANs: MMD GAN As a Gradient Flow

Youssef Mroueh, Truyen Nguyen

We consider the maximum mean discrepancy () GAN problem and propose a parametric kernelized gradient flow that mimics the min-max game in gradient regularized $\mathr…
