A Mechanistic Study of Algorithmic Generalization in Diffusion Models on Modular Arithmetic

Joon Hyeok Kim, Yong-Hyun Park, Mattis Dalsætra Østby +1

Despite their empirical success, how diffusion models generalize remains poorly understood from a mechanistic perspective. In this work, we provide a controlled mechanistic account…

OmniGuide: Universal Spatial Guidance Fields for Enhancing Generalist Robot Policies

Yunzhou Song, Long Le, Yong-Hyun Park +7

Vision-language-action (VLA) models have shown great promise as generalist policies for a large range of relatively simple tasks. However, they demonstrate limited performance on m…

APPLE: Attribute-Preserving Pseudo-Labeling for Diffusion-Based Face Swapping

Jiwon Kang, Yeji Choi, JoungBin Lee +6

Face swapping aims to transfer the identity of a source face onto a target face while preserving target-specific attributes such as pose, expression, lighting, skin tone, and makeu…

DECOR:Decomposition and Projection of Text Embeddings for Text-to-Image Customization

Geonhui Jang, Jin-Hwa Kim, Yong-Hyun Park +3

Text-to-image (T2I) models can effectively capture the content or style of reference images to perform high-quality customization. A representative technique for this is fine-tunin…

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

Yong-Hyun Park, Junghoon Seo, Bomseok Park +2

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

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

Yong-Hyun Park, Mingi Kwon, Jaewoong Choi +2

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

Unsupervised Discovery of Semantic Latent Directions in Diffusion Models

Yong-Hyun Park, Mingi Kwon, Junghyo Jo +1

Despite the success of diffusion models (DMs), we still lack a thorough understanding of their latent space. While image editing with GANs builds upon latent space, DMs rely on edi…
