Meta-CoT: Enhancing Granularity and Generalization in Image Editing

CVPR 2026

Unified multi-modal understanding/generative models have shown improved image editing performance by incorporating fine-grained understanding into their Chain-of-Thought (CoT) process. However, a critical question remains underexplored: what forms of CoT and training strategy can jointly enhance bot

Re-Align: Structured Reasoning-guided Alignment for In-Context Image Generation and Editing

CVPR 2026

In-context image generation and editing (ICGE) enables users to specify visual concepts through interleaved image-text prompts, demanding precise understanding and faithful execution of user intent. Although recent unified multimodal models exhibit promising understanding capabilities, these strengt

TAG-MoE: Task-Aware Gating for Unified Generative Mixture-of-Experts

CVPR 2026

Unified image generation and editing models suffer from severe task interference in dense diffusion transformers architectures, where a shared parameter space must compromise between conflicting objectives (e.g., local editing v.s. subject-driven generation). While the sparse Mixture-of-Experts (MoE

MatRank: Text Re-ranking by Latent Preference Matrix

EMNLP 2022finding

Text ranking plays a key role in providing content that best answers user queries. It is usually divided into two sub-tasks to perform efficient information retrieval given a query: text retrieval and text re-ranking. Recent research on pretrained language models (PLM) has demonstrated efficiency an…

Tenrec: A Large-scale Multipurpose Benchmark Dataset for Recommender Systems

NeurIPS 2022accept

Existing benchmark datasets for recommender systems (RS) either are created at a small scale or involve very limited forms of user feedback. RS models evaluated on such datasets often lack practical values for large-scale real-world applications. In this paper, we describe Tenrec, a novel and publ…
