Logical Closed Loop: Uncovering Object Hallucinations in Large Vision-Language Models

1 code implementation18 Feb 2024 Junfei Wu, Qiang Liu, Ding Wang, Jinghao Zhang, Shu Wu, Liang Wang, Tieniu Tan

In this work, we adopt the intuition that the LVLM tends to respond logically consistently for existent objects but inconsistently for hallucinated objects.

Making Data Work Count

no code implementations29 Nov 2023 Srravya Chandhiramowuli, Alex Taylor, Sara Heitlinger, Ding Wang

To examine this, we draw on sociological and socio-technical scholarship on quantification and develop the lens of a 'regime of counting' that makes explicit the specific counts, practices, actors and structures that underpin the pervasive counting in annotation.

An Adaptive GViT for Gas Mixture Identification and Concentration Estimation

no code implementations10 Mar 2023 Ding Wang, Wenwen Zhang

The gas identification and concentration estimation model called GCN-ViT(GViT) is proposed in this paper; we view the sensor data to be a one-way chain that has only been downscaled to retain the majority of the original in-formation.

Few Clean Instances Help Denoising Distant Supervision

1 code implementation COLING 2022 Yufang Liu, Ziyin Huang, Yijun Wang, Changzhi Sun, Man Lan, Yuanbin Wu, Xiaofeng Mou, Ding Wang

Existing distantly supervised relation extractors usually rely on noisy data for both model training and evaluation, which may lead to garbage-in-garbage-out systems.
