DreamMotion: Space-Time Self-Similarity Score Distillation for Zero-Shot Video Editing

no code implementations18 Mar 2024 Hyeonho Jeong, Jinho Chang, Geon Yeong Park, Jong Chul Ye

Text-driven diffusion-based video editing presents a unique challenge not encountered in image editing literature: establishing real-world motion.

DreamSampler: Unifying Diffusion Sampling and Score Distillation for Image Manipulation

no code implementations18 Mar 2024 Jeongsol Kim, Geon Yeong Park, Jong Chul Ye

Reverse sampling and score-distillation have emerged as main workhorses in recent years for image manipulation using latent diffusion models (LDMs).

Contrastive Denoising Score for Text-guided Latent Diffusion Image Editing

no code implementations30 Nov 2023 Hyelin Nam, Gihyun Kwon, Geon Yeong Park, Jong Chul Ye

A promising recent approach in this realm is Delta Denoising Score (DDS) - an image editing technique based on Score Distillation Sampling (SDS) framework that leverages the rich generative prior of text-to-image diffusion models.

Regularization by Texts for Latent Diffusion Inverse Solvers

no code implementations27 Nov 2023 Jeongsol Kim, Geon Yeong Park, Hyungjin Chung, Jong Chul Ye

The recent advent of diffusion models has led to significant progress in solving inverse problems, leveraging these models as effective generative priors.

Energy-Based Cross Attention for Bayesian Context Update in Text-to-Image Diffusion Models

1 code implementation NeurIPS 2023 Geon Yeong Park, Jeongsol Kim, Beomsu Kim, Sang Wan Lee, Jong Chul Ye

Despite the remarkable performance of text-to-image diffusion models in image generation tasks, recent studies have raised the issue that generated images sometimes cannot capture the intended semantic contents of the text prompts, which phenomenon is often called semantic misalignment.

Self-supervised debiasing using low rank regularization

no code implementations11 Oct 2022 Geon Yeong Park, Chanyong Jung, Sangmin Lee, Jong Chul Ye, Sang Wan Lee

Specifically, we first pretrain a biased encoder in a self-supervised manner with the rank regularization, serving as a semantic bottleneck to enforce the encoder to learn the spuriously correlated attributes.

Training Debiased Subnetworks with Contrastive Weight Pruning

1 code implementation CVPR 2023 Geon Yeong Park, Sangmin Lee, Sang Wan Lee, Jong Chul Ye

Neural networks are often biased to spuriously correlated features that provide misleading statistical evidence that does not generalize.

Information-theoretic regularization for Multi-source Domain Adaptation

no code implementations ICCV 2021 Geon Yeong Park, Sang Wan Lee

Here we adopt an information-theoretic approach to identify and resolve the potential adverse effect of the multiple domain discriminators on MDA: disintegration of domain-discriminative information, limited computational scalability, and a large variance in the gradient of the loss during training.

Reliably fast adversarial training via latent adversarial perturbation

no code implementations ICCV 2021 Geon Yeong Park, Sang Wan Lee

To overcome such limitations, we deviate from the existing input-space-based adversarial training regime and propose a single-step latent adversarial training method (SLAT), which leverages the gradients of latent representation as the latent adversarial perturbation.
