QLIP: A Dynamic Quadtree Vision Prior Enhances MLLM Performance Without Retraining

ICLR 2026poster

Multimodal Large Language Models (MLLMs) encode images into visual tokens, aligning visual and textual signals within a shared latent space to facilitate cross-modal representation learning. The CLIP model is a widely adopted foundational vision language model whose vision encoder has played a criti…

MetaScientist: A Human-AI Synergistic Framework for Automated Mechanical Metamaterial Design

NAACL 2025system demonstrations

The discovery of novel mechanical metamaterials, whose properties are dominated by their engineered structures rather than chemical composition, is a knowledge-intensive and resource-demanding process. To accelerate the design of novel metamaterials, we present MetaScientist, a human-in-the-loop sys…

BLINK: Multimodal Large Language Models Can See but Not Perceive

ECCV 2024poster

"We introduce , a new benchmark for multimodal language models (LLMs) that focuses on core visual perception abilities not found in other evaluations. Most of the tasks can be solved by humans “within a blink” (, relative depth estimation, visual correspondence, forensics detection, and multi-view r…

Cognitive Overload: Jailbreaking Large Language Models with Overloaded Logical Thinking

NAACL 2024findings

While large language models (LLMs) have demonstrated increasing power, they have also called upon studies on their vulnerabilities. As representatives, jailbreak attacks can provoke harmful or unethical responses from LLMs, even after safety alignment. In this paper, we investigate a novel category…

Deceptive Semantic Shortcuts on Reasoning Chains: How Far Can Models Go without Hallucination?

NAACL 2024long

Despite the high performances of large language models (LLMs) across numerous benchmarks, recent research has unveiled their suffering from hallucinations and unfaithful reasoning. This work studies a type of hallucination induced by semantic associations. We investigate to what extent LLMs take sho…

Red Teaming Language Models for Processing Contradictory Dialogues

EMNLP 2024main

Most language models currently available are prone to self-contradiction during dialogues. To mitigate this issue, this study explores a novel contradictory dialogue processing task that aims to detect and modify contradictory statements in a conversation. This task is inspired by research on contex…

Affective and Dynamic Beam Search for Story Generation

EMNLP 2023long findings

Storytelling's captivating potential makes it a fascinating research area, with implications for entertainment, education, therapy, and cognitive studies. In this paper, we propose Affective Story Generator (AffGen) for generating interesting narratives. AffGen introduces `intriguing twists' in narr…

Does Your Model Classify Entities Reasonably? Diagnosing and Mitigating Spurious Correlations in Entity Typing

EMNLP 2022main

Entity typing aims at predicting one or more words that describe the type(s) of a specific mention in a sentence. Due to shortcuts from surface patterns to annotated entity labels and biased training, existing entity typing models are subject to the problem of spurious correlations. To comprehensive…

Unified Semantic Typing with Meaningful Label Inference

NAACL 2022long

Semantic typing aims at classifying tokens or spans of interest in a textual context into semantic categories such as relations, entity types, and event types. The inferred labels of semantic categories meaningfully interpret how machines understand components of text. In this paper, we present UniS…

COVID-19 Literature Knowledge Graph Construction and Drug Repurposing Report Generation

NAACL 2021system demonstrations

To combat COVID-19, both clinicians and scientists need to digest the vast amount of relevant biomedical knowledge in literature to understand the disease mechanism and the related biological functions. We have developed a novel and comprehensive knowledge discovery framework, COVID-KG to extract fi…
