Characteristic Learning for Provable One Step Generation

1 code implementation9 May 2024 Zhao Ding, Chenguang Duan, Yuling Jiao, Ruoxuan Li, Jerry Zhijian Yang, Pingwen Zhang

We propose the characteristic generator, a novel one-step generative model that combines the efficiency of sampling in Generative Adversarial Networks (GANs) with the stable performance of flow-based models.

Deep Conditional Generative Learning: Model and Error Analysis

1 code implementation2 Feb 2024 Jinyuan Chang, Zhao Ding, Yuling Jiao, Ruoxuan Li, Jerry Zhijian Yang

We introduce an Ordinary Differential Equation (ODE) based deep generative method for learning a conditional distribution, named the Conditional Follmer Flow.

Semi-Supervised Deep Sobolev Regression: Estimation, Variable Selection and Beyond

no code implementations9 Jan 2024 Zhao Ding, Chenguang Duan, Yuling Jiao, Jerry Zhijian Yang

We propose SDORE, a semi-supervised deep Sobolev regressor, for the nonparametric estimation of the underlying regression function and its gradient.

Offline Reinforcement Learning with Imbalanced Datasets

no code implementations6 Jul 2023 Li Jiang, Sijie Chen, JieLin Qiu, Haoran Xu, Wai Kin Chan, Zhao Ding

The prevalent use of benchmarks in current offline reinforcement learning (RL) research has led to a neglect of the imbalance of real-world dataset distributions in the development of models.
