Diagnosing and Correcting Concept Omission in Multimodal Diffusion Transformers

ICML 2026poster

Multimodal Diffusion Transformers (MM-DiTs) have achieved remarkable progress in text-to-image generation, yet they frequently suffer from concept omission, where specified objects or attributes fail to emerge in the generated image. By performing linear probing on text tokens, we demonstrate that t…

HeSS: Head Sensitivity Score for Sparsity Redistribution in VGGT

CVPR 2026

Visual Geometry Grounded Transformer (VGGT) has advanced 3D vision, yet its global attention layers suffer from quadratic computational costs that hinder scalability. Several sparsification-based acceleration techniques have been proposed to alleviate this issue, but they often suffer from substanti

Causality-Aware Contrastive Learning for Robust Multivariate Time-Series Anomaly Detection

ICML 2025poster

Utilizing the complex inter-variable causal relationships within multivariate time-series provides a promising avenue toward more robust and reliable multivariate time-series anomaly detection (MTSAD) but remains an underexplored area of research. This paper proposes Causality-Aware contrastive lear…

Disentangled Motion Modeling for Video Frame Interpolation

AAAI 2025technical

Video Frame Interpolation (VFI) aims to synthesize intermediate frames between existing frames to enhance visual smoothness and quality. Beyond the conventional methods based on the reconstruction loss, recent works have employed generative models for improved perceptual quality. However, they requi…

Unsupervised Homography Estimation on Multimodal Image Pair via Alternating Optimization

NeurIPS 2024poster

Estimating the homography between two images is crucial for mid- or high-level vision tasks, such as image stitching and fusion. However, using supervised learning methods is often challenging or costly due to the difficulty of collecting ground-truth data. In response, unsupervised learning approac…

PUCA: Patch-Unshuffle and Channel Attention for Enhanced Self-Supervised Image Denoising

NeurIPS 2023poster

Although supervised image denoising networks have shown remarkable performance on synthesized noisy images, they often fail in practice due to the difference between real and synthesized noise. Since clean-noisy image pairs from the real world are extremely costly to gather, self-supervised learning…
