FineRef: Fine-Grained Error Reflection and Correction for Long-Form Generation with Citations

AAAI 2026technical

Generating with citations is crucial for trustworthy Large Language Models (LLMs), yet even advanced LLMs often produce mismatched or irrelevant citations. Existing methods over-optimize citation fidelity while overlooking relevance to the user query, which degrades answer quality and robustness in

Meerkat-VL: Implicit Risk Safety Alignment in Multimodal LLMs via Perceptual Reasoning and Self-Verification

ICML 2026poster

Multimodal LLMs (MLLMs) are increasingly deployed across diverse applications, but they pose significant safety concerns due to cross-modal interactions. To improve model safety awareness, existing methods rely on explicit-risk preference datasets and reinforcement learning guided by safety rewards.…

SDErasure: Concept-Specific Trajectory Shifting for Concept Erasure via Adaptive Diffusion Classifier

ICLR 2026poster

Concept erasure methods have proven effective in mitigating the potential for text‑to‑image diffusion models to produce harmful content. Nevertheless, prevailing methods based on post fine-tuning introduce substantial disruption to the original model’s parameter distribution and suffer from excessiv…

Seeing is Improving: Visual Feedback for Iterative Text Layout Refinement

CVPR 2026

Recent advances in Multimodal Large Language Models (MLLMs) have enabled automated generation of structured layouts from natural language descriptions. Existing methods typically follow a code-only paradigm that generates code to represent layouts, which are then rendered by graphic engines to produ

UFO: Chain-of-Evaluation for Omni-Condition Alignment in Multi-Modal Image Generation

ICML 2026poster

Multi-modal image generation, particularly subject-driven customization, has garnered growing attention in recent years. Despite the rapid advancement of generative models, their evaluation remains largely lagging. Existing methods, whether embedding-based or Multi-modal Large Language Model (MLLM)-…

GRIP: A Graph-Based Reasoning Instruction Producer

NeurIPS 2025poster

Large-scale, high-quality data is essential for advancing the reasoning capabilities of large language models (LLMs). As publicly available Internet data becomes increasingly scarce, synthetic data has emerged as a crucial research direction. However, existing data synthesis methods often suffer fro…

IGD: Instructional Graphic Design with Multimodal Layer Generation

ICCV 2025poster

Graphic design visually conveys information and data by creating and combining text, images and graphics. Two-stage methods that rely primarily on layout generation lack creativity and intelligence, making graphic design still labor-intensive. Existing diffusion-based methods generate non-editable g…

IterMeme: Expert-Guided Multimodal LLM for Interactive Meme Creation with Layout-Aware Generation

IJCAI 2025

Meme creation is a creative process that blends images and text. However, existing methods lack critical components, failing to support intent-driven caption-layout generation and personalized generation, making it difficult to generate high-quality memes. To address this limitation, we propose Iter

Mask^2DiT: Dual Mask-based Diffusion Transformer for Multi-Scene Long Video Generation

CVPR 2025poster

Sora has unveiled the immense potential of the Diffusion Transformer (DiT) architecture in single-scene video generation. However, the more challenging task of multi-scene video generation, which offers broader applications, remains relatively underexplored. To bridge this gap, we propose Mask^2DiT,…

DEADiff: An Efficient Stylization Diffusion Model with Disentangled Representations

CVPR 2024highlight

The diffusion-based text-to-image model harbors immense potential in transferring reference style. However current encoder-based approaches significantly impair the text controllability of text-to-image models while transferring styles. In this paper we introduce DEADiff to address this issue using…

DreamIdentity: Enhanced Editability for Efficient Face-Identity Preserved Image Generation

AAAI 2024technical

While large-scale pre-trained text-to-image models can synthesize diverse and high-quality human-centric images, an intractable problem is how to preserve the face identity and follow the text prompts simultaneously for conditioned input face images and texts. Despite existing encoder-based methods…

Crossing the Gap: Domain Generalization for Image Captioning

CVPR 2023poster

Existing image captioning methods are under the assumption that the training and testing data are from the same domain or that the data from the target domain (i.e., the domain that testing data lie in) are accessible. However, this assumption is invalid in real-world applications where the data fro…

ER-SAN: Enhanced-Adaptive Relation Self-Attention Network for Image Captioning

IJCAI 2022poster

Image captioning (IC), bringing vision to language, has drawn extensive attention. Precisely describing visual relations between image objects is a key challenge in IC. We argue that the visual relations, that is geometric positions (i.e., distance and size) and semantic interactions (i.e., actions…

From Two to One: A New Scene Text Recognizer With Visual Language Modeling Network

ICCV 2021poster

In this paper, we abandon the dominant complex language model and rethink the linguistic learning process in the scene text recognition. Different from previous methods considering the visual and linguistic information in two separate structures, we propose a Visual Language Modeling Network (Vision…

Read Like Humans: Autonomous, Bidirectional and Iterative Language Modeling for Scene Text Recognition

CVPR 2021poster

Linguistic knowledge is of great benefit to scene text recognition. However, how to effectively model linguistic rules in end-to-end deep networks remains a research challenge. In this paper, we argue that the limited capacity of language models comes from: 1) implicitly language modeling; 2) unidir…
