Direct Unlearning Optimization for Robust and Safe Text-to-Image Models

no code implementations17 Jul 2024 Yong-Hyun Park, Sangdoo Yun, Jin-Hwa Kim, Junho Kim, Geonhui Jang, Yonghyun Jeong, Junghyo Jo, Gayoung Lee

In this paper, we propose Direct Unlearning Optimization (DUO), a novel framework for removing Not Safe For Work (NSFW) content from T2I models while preserving their performance on unrelated topics.

Geometric Remove-and-Retrain (GOAR): Coordinate-Invariant eXplainable AI Assessment

no code implementations17 Jul 2024 Yong-Hyun Park, Junghoon Seo, Bomseok Park, Seongsu Lee, Junghyo Jo

Identifying the relevant input features that have a critical influence on the output results is indispensable for the development of explainable artificial intelligence (XAI).

Upsample Guidance: Scale Up Diffusion Models without Training

no code implementations2 Apr 2024 Juno Hwang, Yong-Hyun Park, Junghyo Jo

We demonstrate that upsample guidance can be applied to various models, such as pixel-space, latent space, and video diffusion models.

Resolution Chromatography of Diffusion Models

no code implementations7 Dec 2023 Juno Hwang, Yong-Hyun Park, Junghyo Jo

In this paper, we introduce "resolution chromatography" that indicates the signal generation rate of each resolution, which is very helpful concept to mathematically explain this coarse-to-fine behavior in generation process, to understand the role of noise schedule, and to design time-dependent modulation.

Understanding the Latent Space of Diffusion Models through the Lens of Riemannian Geometry

1 code implementation NeurIPS 2023 Yong-Hyun Park, Mingi Kwon, Jaewoong Choi, Junghyo Jo, Youngjung Uh

Remarkably, our discovered local latent basis enables image editing capabilities by moving $\mathbf{x}_t$, the latent space of DMs, along the basis vector at specific timesteps.

Unsupervised Discovery of Semantic Latent Directions in Diffusion Models

no code implementations24 Feb 2023 Yong-Hyun Park, Mingi Kwon, Junghyo Jo, Youngjung Uh

Despite the success of diffusion models (DMs), we still lack a thorough understanding of their latent space.
