Picturing Ambiguity: A Visual Twist on the Winograd Schema Challenge

1 code implementation25 May 2024 Brendan Park, Madeline Janecek, Naser Ezzati-Jivan, Yifeng Li, Ali Emami

Utilizing GPT-4 for prompt generation and Diffusion Attentive Attribution Maps (DAAM) for heatmap analysis, we propose a novel evaluation framework that isolates the models' ability in pronoun disambiguation from other visual processing challenges.

Generative Category-Level Shape and Pose Estimation with Semantic Primitives

1 code implementation3 Oct 2022 Guanglin Li, Yifeng Li, Zhichao Ye, Qihang Zhang, Tao Kong, Zhaopeng Cui, Guofeng Zhang

Then, by using a SIM(3)-invariant shape descriptor, we gracefully decouple the shape and pose of an object, thus supporting latent shape optimization of target objects in arbitrary poses.

CAIBC: Capturing All-round Information Beyond Color for Text-based Person Retrieval

no code implementations13 Sep 2022 Zijie Wang, Aichun Zhu, Jingyi Xue, Xili Wan, Chao Liu, Tian Wang, Yifeng Li

Indeed, color information is an important decision-making accordance for retrieval, but the over-reliance on color would distract the model from other key clues (e. g. texture information, structural information, etc.
