Learning Decomposable and Debiased Representations via Attribute-Centric Information Bottlenecks

no code implementations21 Mar 2024 Jinyung Hong, Eun Som Jeon, Changhoon Kim, Keun Hee Park, Utkarsh Nath, Yezhou Yang, Pavan Turaga, Theodore P. Pavlic

Biased attributes, spuriously correlated with target labels in a dataset, can problematically lead to neural networks that learn improper shortcuts for classifications and limit their capabilities for out-of-distribution (OOD) generalization.

ECLIPSE: A Resource-Efficient Text-to-Image Prior for Image Generations

no code implementations7 Dec 2023 Maitreya Patel, Changhoon Kim, Sheng Cheng, Chitta Baral, Yezhou Yang

The T2I prior model alone adds a billion parameters compared to the Latent Diffusion Models, which increases the computational and high-quality data requirements.

WOUAF: Weight Modulation for User Attribution and Fingerprinting in Text-to-Image Diffusion Models

no code implementations7 Jun 2023 Changhoon Kim, Kyle Min, Maitreya Patel, Sheng Cheng, Yezhou Yang

The rapid advancement of generative models, facilitating the creation of hyper-realistic images from textual descriptions, has concurrently escalated critical societal concerns such as misinformation.

Attributing Image Generative Models using Latent Fingerprints

1 code implementation17 Apr 2023 GuangYu Nie, Changhoon Kim, Yezhou Yang, Yi Ren

This paper investigates the use of latent semantic dimensions as fingerprints, from where we can analyze the effects of design variables, including the choice of fingerprinting dimensions, strength, and capacity, on the accuracy-quality tradeoff.

Decentralized Attribution of Generative Models

no code implementations ICLR 2021 Changhoon Kim, Yi Ren, Yezhou Yang

Growing applications of generative models have led to new threats such as malicious personation and digital copyright infringement.
