GMValuator: Similarity-based Data Valuation for Generative Models

no code implementations21 Apr 2023 Jiaxi Yang, Wenglong Deng, Benlin Liu, Yangsibo Huang, James Zou, Xiaoxiao Li

Specifically, we introduce Generative Model Valuator (GMValuator), the first training-free and model-agnostic approach to provide data valuation for generation tasks.

TIFA: Accurate and Interpretable Text-to-Image Faithfulness Evaluation with Question Answering

1 code implementation ICCV 2023 Yushi Hu, Benlin Liu, Jungo Kasai, Yizhong Wang, Mari Ostendorf, Ranjay Krishna, Noah A Smith

We introduce TIFA (Text-to-Image Faithfulness evaluation with question Answering), an automatic evaluation metric that measures the faithfulness of a generated image to its text input via visual question answering (VQA).

Unleashing Text-to-Image Diffusion Models for Visual Perception

2 code implementations ICCV 2023 Wenliang Zhao, Yongming Rao, Zuyan Liu, Benlin Liu, Jie zhou, Jiwen Lu

In this paper, we propose VPD (Visual Perception with a pre-trained Diffusion model), a new framework that exploits the semantic information of a pre-trained text-to-image diffusion model in visual perception tasks.

RandomRooms: Unsupervised Pre-training from Synthetic Shapes and Randomized Layouts for 3D Object Detection

2 code implementations ICCV 2021 Yongming Rao, Benlin Liu, Yi Wei, Jiwen Lu, Cho-Jui Hsieh, Jie zhou

In particular, we propose to generate random layouts of a scene by making use of the objects in the synthetic CAD dataset and learn the 3D scene representation by applying object-level contrastive learning on two random scenes generated from the same set of synthetic objects.

DynamicViT: Efficient Vision Transformers with Dynamic Token Sparsification

1 code implementation NeurIPS 2021 Yongming Rao, Wenliang Zhao, Benlin Liu, Jiwen Lu, Jie zhou, Cho-Jui Hsieh

Based on this observation, we propose a dynamic token sparsification framework to prune redundant tokens progressively and dynamically based on the input.

Robust Object Detection via Instance-Level Temporal Cycle Confusion

1 code implementation ICCV 2021 Xin Wang, Thomas E. Huang, Benlin Liu, Fisher Yu, Xiaolong Wang, Joseph E. Gonzalez, Trevor Darrell

Building reliable object detectors that are robust to domain shifts, such as various changes in context, viewpoint, and object appearances, is critical for real-world applications.
