Adaptive Liquidity Provision in Uniswap V3 with Deep Reinforcement Learning

no code implementations18 Sep 2023 Haochen Zhang, Xi Chen, Lin F. Yang

The DRL policy aims to optimize trading fees earned by LPs against associated costs, such as gas fees and hedging expenses, which is referred to as loss-versus-rebalancing (LVR).

Resilient Distribution System Restoration with Communication Recovery by Drone Small Cells

no code implementations31 Mar 2022 Haochen Zhang, Chen Chen, Shunbo Lei, Zhaohong Bie

Distribution system (DS) restoration after natural disasters often faces the challenge of communication failures to feeder automation (FA) facilities, resulting in prolonged load pick-up process.

Unsupervised Real-World Super-Resolution: A Domain Adaptation Perspective

no code implementations ICCV 2021 Wei Wang, Haochen Zhang, Zehuan Yuan, Changhu Wang

A popular attempts towards the challenge is unpaired generative adversarial networks, which generate "real" LR counterparts from real HR images using image-to-image translation and then perform super-resolution from "real" LR->SR.

Learning by Passing Tests, with Application to Neural Architecture Search

no code implementations30 Nov 2020 Xuefeng Du, Haochen Zhang, Pengtao Xie

We propose a multi-level optimization framework to formulate LPT, where the tester learns to create difficult and meaningful tests and the learner learns to pass these tests.

Is There Tradeoff between Spatial and Temporal in Video Super-Resolution?

no code implementations13 Mar 2020 Haochen Zhang, Dong Liu, Zhiwei Xiong

Recent advances of deep learning lead to great success of image and video super-resolution (SR) methods that are based on convolutional neural networks (CNN).

On The Classification-Distortion-Perception Tradeoff

no code implementations NeurIPS 2019 Dong Liu, Haochen Zhang, Zhiwei Xiong

In this paper, we extend the previous perception-distortion tradeoff to the case of classification-distortion-perception (CDP) tradeoff, where we introduced the classification error rate of the restored signal in addition to distortion and perceptual difference.
