Aligning Modalities in Vision Large Language Models via Preference Fine-tuning

1 code implementation18 Feb 2024 Yiyang Zhou, Chenhang Cui, Rafael Rafailov, Chelsea Finn, Huaxiu Yao

This procedure is not perfect and can cause the model to hallucinate - provide answers that do not accurately reflect the image, even when the core LLM is highly factual and the vision backbone has sufficiently complete representations.

How Many Unicorns Are in This Image? A Safety Evaluation Benchmark for Vision LLMs

1 code implementation27 Nov 2023 Haoqin Tu, Chenhang Cui, Zijun Wang, Yiyang Zhou, Bingchen Zhao, Junlin Han, Wangchunshu Zhou, Huaxiu Yao, Cihang Xie

Different from prior studies, we shift our focus from evaluating standard performance to introducing a comprehensive safety evaluation suite, covering both out-of-distribution (OOD) generalization and adversarial robustness.

Holistic Analysis of Hallucination in GPT-4V(ision): Bias and Interference Challenges

1 code implementation6 Nov 2023 Chenhang Cui, Yiyang Zhou, Xinyu Yang, Shirley Wu, Linjun Zhang, James Zou, Huaxiu Yao

To bridge this gap, we introduce a new benchmark, namely, the Bias and Interference Challenges in Visual Language Models (Bingo).

Bright Channel Prior Attention for Multispectral Pedestrian Detection

no code implementations22 May 2023 Chenhang Cui, Jinyu Xie, Yechenhao Yang

The method uses the V-channel of the HSV image of the thermal image as an attention map to trigger the unsupervised auto-encoder for visible light images, which gradually emphasizes pedestrian features across layers.

Deep Multi-View Subspace Clustering with Anchor Graph

1 code implementation11 May 2023 Chenhang Cui, Yazhou Ren, Jingyu Pu, Xiaorong Pu, Lifang He

To significantly reduce the complexity, we construct an anchor graph with small size for each view.
