Dual-IPO: Dual-Iterative Preference Optimization for Text-to-Video Generation

ICLR 2026poster

Recent advances in video generation have enabled thrilling experiences in producing realistic videos driven by scalable diffusion transformers. However, they usually fail to produce satisfactory outputs that are aligned to users' authentic demands and preferences. In this work, we introduce Dual-Ite…

Uni-CoT: Towards Unified Chain-of-Thought Reasoning Across Text and Vision

ICLR 2026poster

Chain-of-Thought (CoT) reasoning has proven effective in enhancing Large Language Models (LLMs) on complex tasks by decomposing problems into step-wise solutions. However, extending CoT to multi-modal settings remains challenging, as it requires modeling transitions of visual states alongside textua…

An Empirical Study and Analysis of Text-to-Image Generation Using Large Language Model-Powered Textual Representation

ECCV 2024poster

"One critical prerequisite for faithful text-to-image generation is the accurate understanding of text inputs. Existing methods leverage the text encoder of the CLIP model to represent input prompts. However, the pre-trained CLIP model can merely encode English with a maximum token length of 77. Mor…

Contrastive Learning with High-Quality and Low-Quality Augmented Data for Query-Focused Summarization

ICASSP 2024accepted

Unlike general text summarization, Query-focused summarization (QFS) is severely limited by insufficient datasets, forcing previous research to transform datasets from other tasks into QFS format for data augmentation. However, this approach has resulted in two problems: the task and traintest gaps.…

Improving Copy-oriented Text Generation via EDU Copy Mechanism

COLING 2024main

Many text generation tasks are copy-oriented. For instance, nearly 30% content of news summaries is copied. The copy rate is even higher in Grammatical Error Correction (GEC). However, existing generative models generate texts through word-by-word decoding, which may lead to factual inconsistencies…

Diffusion Language Model with Query-Document Relevance for Query-Focused Summarization

EMNLP 2023long findings

Query-Focused Summarization (QFS) aims to generate summaries from source documents that can answer specific queries. Although the QFS task has gained increasing attention recently, its development is constrained by the fact that mainstream QFS models are BART variants, which are autoregressive and…
