Parameter Inference of Time Series by Delay Embeddings and Learning Differentiable Operators

no code implementations11 Mar 2022 Alex Tong Lin, Adrian S. Wong, Robert Martin, Stanley J. Osher, Daniel Eckhardt

We provide a method to identify system parameters of dynamical systems, called ID-ODE -- Inference by Differentiation and Observing Delay Embeddings.

Wasserstein Proximal of GANs

no code implementations ICLR 2019 Alex Tong Lin, Wuchen Li, Stanley Osher, Guido Montufar

We introduce a new method for training generative adversarial networks by applying the Wasserstein-2 metric proximal on the generators.

Wasserstein-based Projections with Applications to Inverse Problems

2 code implementations5 Aug 2020 Howard Heaton, Samy Wu Fung, Alex Tong Lin, Stanley Osher, Wotao Yin

To bridge this gap, we present a new algorithm that takes samples from the manifold of true data as input and outputs an approximation of the projection operator onto this manifold.

Alternating the Population and Control Neural Networks to Solve High-Dimensional Stochastic Mean-Field Games

1 code implementation24 Feb 2020 Alex Tong Lin, Samy Wu Fung, Wuchen Li, Levon Nurbekyan, Stanley J. Osher

By phrasing the problem in this manner, solving the MFG can be interpreted as a special case of training a generative adversarial network (GAN).

Wasserstein Diffusion Tikhonov Regularization

no code implementations15 Sep 2019 Alex Tong Lin, Yonatan Dukler, Wuchen Li, Guido Montufar

We propose regularization strategies for learning discriminative models that are robust to in-class variations of the input data.

Decentralized Multi-Agents by Imitation of a Centralized Controller

no code implementations6 Feb 2019 Alex Tong Lin, Mark J. Debord, Katia Estabridis, Gary Hewer, Guido Montufar, Stanley Osher

In order to obtain multi-agents that act in a decentralized manner, we introduce a novel algorithm under the popular framework of centralized training, but decentralized execution.
