Scone: Bridging Composition and Distinction in Subject-Driven Image Generation via Unified Understanding-Generation Modeling

CVPR 2026

Subject-driven image generation has advanced from single- to multi-subject composition, while neglecting distinction, the ability to distinguish and generate the correct subject when inputs contain multiple candidates. This limitation restricts effectiveness in complex, realistic visual settings. We

Differential Coding for Training-Free ANN-to-SNN Conversion

ICML 2025poster

Spiking Neural Networks (SNNs) exhibit significant potential due to their low energy consumption. Converting Artificial Neural Networks (ANNs) to SNNs is an efficient way to achieve high-performance SNNs. However, many conversion methods are based on rate coding, which requires numerous spikes and l…

KnowCoder-X: Boosting Multilingual Information Extraction via Code

ACL 2025finding

Empirical evidence indicates that LLMs exhibit spontaneous cross-lingual alignment. However, although LLMs show promising cross-lingual alignment in Information Extraction (IE), a significant imbalance across languages persists, highlighting an underlying deficiency. To address this, we propose Know…

Pioneering Explainable Video Fact-Checking with a New Dataset and Multi-role Multimodal Model Approach

AAAI 2025technical

Existing video fact-checking datasets often lack detailed evidence and explanations, compromising the reliability and interpretability of fact-checking methods. To address these gaps, we developed a novel dataset featuring comprehensive annotations for each news item, including veracity labels, the…

SOTA: Spike-Navigated Optimal TrAnsport Saliency Region Detection in Composite-bias Videos

IJCAI 2025

Existing saliency detection methods struggle in real-world scenarios due to motion blur and occlusions. In contrast, spike cameras, with their high temporal resolution, significantly enhance visual saliency maps. However, the composite noise inherent to spike camera imaging introduces discontinuitie

Towards Event Extraction with Massive Types: LLM-based Collaborative Annotation and Partitioning Extraction

EMNLP 2025

Developing a general-purpose system that can extract events with massive types is a long-standing target in Event Extraction (EE). In doing so, the basic challenge comes from the absence of an efficient and effective annotation framework to construct the corresponding datasets. In this paper, we pro

Local Consistency Guidance: Personalized Stylization Method of Face Video (Student Abstract)

AAAI 2024technical

Face video stylization aims to convert real face videos into specified reference styles. While one-shot methods perform well in single-image stylization, ensuring continuity between frames and retaining the original facial expressions present challenges in video stylization. To address these issues,…

Background Disturbance Mitigation for Video Captioning Via Entity-Action Relocation

ICASSP 2023accepted

Video captioning aims to generate sentences to accurately describe the video content, in which video background plays the role of prompts. State-of-the-art methods tend to explore richer video representations adequately, fusing with language to improve caption quality, which has shown great success.…

Background-Weakening Consistency Regularization for Semi-Supervised Video Action Detection

ICASSP 2023accepted

Consistency-based techniques have produced state-of-the-art results in semi-supervised action detection. When the model false detects the dynamic information in the background as an action, spatio-temporal consistency calculations can hardly reflect this false detection result. We consider weakening…

Bat: Bi-Alignment Based On Transformation in Multi-Target Domain Adaptation for Semantic Segmentation

ICASSP 2023accepted

While enlightening progress has been made recently in single-target domain adaptive semantic segmentation (ST-DASS), the multi-peak distributed multi-target domain cannot be directly aligned well with the single-peak distributed source domain. As a result, it is impossible for existing methods to ha…

Neighborhood Information-Based Label Refinement for Person Re-Identification with Label Noise

ICASSP 2023accepted

The existing excellent person re-identification (Re-ID) model is still affected by the samples with the incorrect labels. It is difficult to accurately annotate person images in the real scene, resulting in label noise. To avoid fitting to the noisy labels, a common solution in Re-ID is to replace t…
