UniArk: Improving Generalisation and Consistency for Factual Knowledge Extraction through Debiasing

1 code implementation1 Apr 2024 Yijun Yang, Jie He, Pinzhen Chen, Víctor Gutiérrez-Basulto, Jeff Z. Pan

We hypothesize that simultaneously debiasing these objectives can be the key to generalisation over unseen prompts.

Genuine Knowledge from Practice: Diffusion Test-Time Adaptation for Video Adverse Weather Removal

no code implementations12 Mar 2024 Yijun Yang, Hongtao Wu, Angelica I. Aviles-Rivero, Yulun Zhang, Jing Qin, Lei Zhu

Although ViWS-Net is proposed to remove adverse weather conditions in videos with a single set of pre-trained weights, it is seriously blinded by seen weather at train-time and degenerates when coming to unseen weather during test-time.

GuardT2I: Defending Text-to-Image Models from Adversarial Prompts

no code implementations3 Mar 2024 Yijun Yang, Ruiyuan Gao, Xiao Yang, Jianyuan Zhong, Qiang Xu

Recent advancements in Text-to-Image (T2I) models have raised significant safety concerns about their potential misuse for generating inappropriate or Not-Safe-For-Work (NSFW) contents, despite existing countermeasures such as NSFW classifiers or model fine-tuning for inappropriate concept removal.

Vivim: a Video Vision Mamba for Medical Video Object Segmentation

1 code implementation25 Jan 2024 Yijun Yang, Zhaohu Xing, Chunwang Huang, Lei Zhu

Traditional convolutional neural networks have a limited receptive field while transformer-based networks are mediocre in constructing long-term dependency from the perspective of computational complexity.

SegMamba: Long-range Sequential Modeling Mamba For 3D Medical Image Segmentation

1 code implementation24 Jan 2024 Zhaohu Xing, Tian Ye, Yijun Yang, Guang Liu, Lei Zhu

Our SegMamba, in contrast to Transformer-based methods, excels in whole volume feature modeling from a state space model standpoint, maintaining superior processing speed, even with volume features at a resolution of {$64\times 64\times 64$}.

MMA-Diffusion: MultiModal Attack on Diffusion Models

2 code implementations29 Nov 2023 Yijun Yang, Ruiyuan Gao, Xiaosen Wang, Tsung-Yi Ho, Nan Xu, Qiang Xu

In recent years, Text-to-Image (T2I) models have seen remarkable advancements, gaining widespread adoption.

Embodied Multi-Modal Agent trained by an LLM from a Parallel TextWorld

1 code implementation28 Nov 2023 Yijun Yang, Tianyi Zhou, Kanxue Li, Dapeng Tao, Lusong Li, Li Shen, Xiaodong He, Jing Jiang, Yuhui Shi

While large language models (LLMs) excel in a simulated world of texts, they struggle to interact with the more realistic world without perceptions of other modalities such as visual or audio signals.

Video Adverse-Weather-Component Suppression Network via Weather Messenger and Adversarial Backpropagation

1 code implementation ICCV 2023 Yijun Yang, Angelica I. Aviles-Rivero, Huazhu Fu, Ye Liu, Weiming Wang, Lei Zhu

In this work, we propose the first framework for restoring videos from all adverse weather conditions by developing a video adverse-weather-component suppression network (ViWS-Net).

Continual Task Allocation in Meta-Policy Network via Sparse Prompting

1 code implementation29 May 2023 Yijun Yang, Tianyi Zhou, Jing Jiang, Guodong Long, Yuhui Shi

We address it by "Continual Task Allocation via Sparse Prompting (CoTASP)", which learns over-complete dictionaries to produce sparse masks as prompts extracting a sub-network for each task from a meta-policy network.

DiffMIC: Dual-Guidance Diffusion Network for Medical Image Classification

1 code implementation19 Mar 2023 Yijun Yang, Huazhu Fu, Angelica I. Aviles-Rivero, Carola-Bibiane Schönlieb, Lei Zhu

However, while a substantial amount of diffusion-based research has focused on generative tasks, few studies have applied diffusion models to general medical image classification.

Pareto Policy Pool for Model-based Offline Reinforcement Learning

no code implementations ICLR 2022 Yijun Yang, Jing Jiang, Tianyi Zhou, Jie Ma, Yuhui Shi

Model-based offline RL instead trains an environment model using a dataset of pre-collected experiences so online RL methods can learn in an offline manner by solely interacting with the model.
