InstructBrush: Learning Attention-based Instruction Optimization for Image Editing

no code implementations27 Mar 2024 Ruoyu Zhao, Qingnan Fan, Fei Kou, Shuai Qin, Hong Gu, Wei Wu, Pengcheng Xu, Mingrui Zhu, Nannan Wang, Xinbo Gao

Two key techniques are introduced into InstructBrush, Attention-based Instruction Optimization and Transformation-oriented Instruction Initialization, to address the limitations of the previous method in terms of inversion effects and instruction generalization.

Molecular De Novo Design through Transformer-based Reinforcement Learning

no code implementations9 Oct 2023 Pengcheng Xu, Tao Feng, Tianfan Fu, Siddhartha Laghuvarapu, Jimeng Sun

In contrast to the traditional RNN-based models, our proposed method exhibits superior performance in generating compounds predicted to be active against various biological targets, capturing long-term dependencies in the molecular structure sequence.

Class Overwhelms: Mutual Conditional Blended-Target Domain Adaptation

1 code implementation3 Feb 2023 Pengcheng Xu, Boyu Wang, Charles Ling

We demonstrate that domain labels are not directly necessary for BTDA if categorical distributions of various domains are sufficiently aligned even facing the imbalance of domains and the label distribution shift of classes.

When Source-Free Domain Adaptation Meets Learning with Noisy Labels

no code implementations31 Jan 2023 Li Yi, Gezheng Xu, Pengcheng Xu, Jiaqi Li, Ruizhi Pu, Charles Ling, A. Ian McLeod, Boyu Wang

We also prove that such a difference makes existing LLN methods that rely on their distribution assumptions unable to address the label noise in SFDA.

Predicting Li-ion Battery Cycle Life with LSTM RNN

no code implementations8 Jul 2022 Pengcheng Xu, Yunfeng Lu

Efficient and accurate remaining useful life prediction is a key factor for reliable and safe usage of lithium-ion batteries.

HASCO: Towards Agile HArdware and Software CO-design for Tensor Computation

1 code implementation4 May 2021 Qingcheng Xiao, Size Zheng, Bingzhe Wu, Pengcheng Xu, Xuehai Qian, Yun Liang

Second, the overall design space composed of HW/SW partitioning, hardware optimization, and software optimization is huge.

Coordinated Cyber-Attack Detection Model of Cyber-Physical Power System Based on the Operating State Data Link

no code implementations27 Feb 2021 Lei Wang, Pengcheng Xu, Zhaoyang Qu, Xiaoyong Bo, Yunchang Dong, Zhenming Zhang, Yang Li

Existing coordinated cyber-attack detection methods have low detection accuracy and efficiency and poor generalization ability due to difficulties dealing with unbalanced attack data samples, high data dimensionality, and noisy data sets.

Wasserstein Distance Based Domain Adaptation for Object Detection

no code implementations18 Sep 2019 Pengcheng Xu, Prudhvi Gurram, Gene Whipps, Rama Chellappa

Prior approaches utilize adversarial training based on cross entropy between the source and target domain distributions to learn a shared feature mapping that minimizes the domain gap.

A Directed Acyclic Graph Approach to Online Log Parsing

no code implementations12 Jun 2018 Pinjia He, Jieming Zhu, Pengcheng Xu, Zibin Zheng, Michael R. Lyu

A typical log-based system reliability management procedure is to first parse log messages because of their unstructured format; and apply data mining techniques on the parsed logs to obtain critical system behavior information.
