AIGCs Confuse AI Too: Investigating and Explaining Synthetic Image-induced Hallucinations in Large Vision-Language Models

no code implementations13 Mar 2024 YiFei Gao, Jiaqi Wang, Zhiyu Lin, Jitao Sang

Remarkably, our findings shed light on a consistent AIGC \textbf{hallucination bias}: the object hallucinations induced by synthetic images are characterized by a greater quantity and a more uniform position distribution, even these synthetic images do not manifest unrealistic or additional relevant visual features compared to natural images.

Causality is all you need

no code implementations21 Nov 2023 Ning Xu, YiFei Gao, Hongshuo Tian, Yongdong Zhang, An-An Liu

In this paper, we propose the Causal Graph Routing (CGR) framework, an integrated causal scheme relying entirely on the intervention mechanisms to reveal the cause-effect forces hidden in data.

Recently, with the emergence of numerous Large Language Models (LLMs), the implementation of AI has entered a new era.

Towards Black-box Adversarial Example Detection: A Data Reconstruction-based Method

no code implementations3 Jun 2023 YiFei Gao, Zhiyu Lin, Yunfan Yang, Jitao Sang

Black-box attack, which is a more realistic threat and has led to various black-box adversarial training-based defense methods, however, does not attract considerable attention in adversarial example detection.

Investigating and Explaining the Frequency Bias in Image Classification

1 code implementation6 May 2022 Zhiyu Lin, YiFei Gao, Jitao Sang

Specifically, our investigations verify that the spectral density of datasets mainly affects the learning priority, while the class consistency mainly affects the feature discrimination.
