Model Already Knows the Best Noise: Bayesian Active Noise Selection via Attention in Video Diffusion Model

ICLR 2026poster

The choice of initial noise strongly affects quality and prompt alignment in video diffusion; different seeds for the same prompt can yield drastically different results. While recent methods use externally designed priors (e.g., frequency filtering or inter-frame smoothing), they often overlook int…

PLADIS: Pushing the Limits of Attention in Diffusion Models at Inference Time by Leveraging Sparsity

ICCV 2025poster

Diffusion models have shown impressive results in generating high-quality conditional samples using guidance techniques such as Classifier-Free Guidance (CFG). However, existing methods often require additional training or neural function evaluations (NFEs), making them incompatible with guidance-di…

OTSeg: Multi-prompt Sinkhorn Attention for Zero-Shot Semantic Segmentation

ECCV 2024poster

"The recent success of CLIP has demonstrated promising results in zero-shot semantic segmentation by transferring muiltimodal knowledge to pixel-level classification. However, leveraging pre-trained CLIP knowledge to closely align text embeddings with pixel embeddings still has limitations in existi…

Unpaired Image-to-Image Translation via Neural Schrödinger Bridge

ICLR 2024poster

Diffusion models are a powerful class of generative models which simulate stochastic differential equations (SDEs) to generate data from noise. While diffusion models have achieved remarkable progress, they have limitations in unpaired image-to-image (I2I) translation tasks due to the Gaussian prior…

Noise Distribution Adaptive Self-Supervised Image Denoising Using Tweedie Distribution and Score Matching

CVPR 2022poster

Tweedie distributions are a special case of exponential dispersion models, which are often used in classical statistics as distributions for generalized linear models. Here, we reveal that Tweedie distributions also play key roles in modern deep learning era, leading to a distribution independent se…

Noise2Score: Tweedie’s Approach to Self-Supervised Image Denoising without Clean Images

NeurIPS 2021poster

Recently, there has been extensive research interest in training deep networks to denoise images without clean reference. However, the representative approaches such as Noise2Noise, Noise2Void, Stein's unbiased risk estimator (SURE), etc. seem to differ from one another and it is difficult to fin…
