Composite Sorting

no code implementations12 Mar 2023 Job Boerma, Aleh Tsyvinski, Ruodu Wang, Zhenyuan Zhang

This paper introduces a labor market model with concave mismatch costs, which arise when firms mitigate the cost of mismatch.

Simultaneous Optimal Transport

no code implementations10 Jan 2022 Ruodu Wang, Zhenyuan Zhang

We propose a general framework of mass transport between vector-valued measures, which will be called simultaneous optimal transport (SOT).

FedDTG:Federated Data-Free Knowledge Distillation via Three-Player Generative Adversarial Networks

no code implementations10 Jan 2022 Lingzhi Gao, Zhenyuan Zhang, Chao Wu

While existing federated learning approaches primarily focus on aggregating local models to construct a global model, in realistic settings, some clients may be reluctant to share their private models due to the inclusion of privacy-sensitive information.

Sparse-softmax: A Simpler and Faster Alternative Softmax Transformation

no code implementations23 Dec 2021 Shaoshi Sun, Zhenyuan Zhang, BoCheng Huang, Pengbin Lei, Jianlin Su, Shengfeng Pan, Jiarun Cao

The softmax function is widely used in artificial neural networks for the multiclass classification problems, where the softmax transformation enforces the output to be positive and sum to one, and the corresponding loss function allows to use maximum likelihood principle to optimize the model.

A limit theorem for Bernoulli convolutions and the $Φ$-variation of functions in the Takagi class

no code implementations4 Feb 2021 Xiyue Han, Alexander Schied, Zhenyuan Zhang

We consider a probabilistic approach to compute the Wiener--Young $\Phi$-variation of fractal functions in the Takagi class.

TAMPC: A Controller for Escaping Traps in Novel Environments

1 code implementation23 Oct 2020 Sheng Zhong, Zhenyuan Zhang, Nima Fazeli, Dmitry Berenson

We propose an approach to online model adaptation and control in the challenging case of hybrid and discontinuous dynamics where actions may lead to difficult-to-escape "trap" states, under a given controller.
