Contextualized Visual Personalization in Vision-Language Models

ICML 2026poster

Despite recent progress in vision-language models (VLMs), existing approaches often fail to generate personalized responses based on the user's specific experiences, as they lack the ability to associate visual inputs with a user’s accumulated visual-textual context. We newly formalize this challeng…

Correcting Negative Bias in Large Language Models through Negative Attention Score Alignment

NAACL 2025long

A binary decision task, like yes-no questions or answer verification, reflects a significant real-world scenario such as where users look for confirmation about the correctness of their decisions on specific issues. In this work, we observe that language models exhibit a negative bias in the binary…

Does Your Voice Assistant Remember? Analyzing Conversational Context Recall and Utilization in Voice Interaction Models

ACL 2025finding

Recent advancements in multi-turn voice interaction models have improved user-model communication. However, while closed-source models effectively retain and recall past utterances, whether open-source models share this ability remains unexplored. To fill this gap, we systematically evaluate how wel…

Know "No" Better: A Data-Driven Approach for Enhancing Negation Awareness in CLIP

ICCV 2025poster

While CLIP has significantly advanced multimodal understanding by bridging vision and language, the inability to grasp negation -- such as failing to differentiate concepts like "parking" from "no parking" -- poses substantial challenges.By analyzing the data used in the public CLIP model's pre-trai…

Unleashing Multi-Hop Reasoning Potential in Large Language Models through Repetition of Misordered Context

NAACL 2025findings

Multi-hop reasoning, which requires multi-step reasoning based on the supporting documents within a given context, remains challenging for large language models (LLMs). LLMs often struggle to filter out irrelevant documents within the context, and their performance is sensitive to the absolute posit…

Controlled Text Generation for Black-box Language Models via Score-based Progressive Editor

ACL 2024long

Controlled text generation, aiming to ensure that language models produce text containing only the desired domain or corpus attributes, is immensely crucial in the practical application of language models. Existing methods, however, are inapplicable to black-box models or suffer a significant trade-…

Interactive Text-to-Image Retrieval with Large Language Models: A Plug-and-Play Approach

ACL 2024long

In this paper, we primarily address the issue of dialogue-form context query within the interactive text-to-image retrieval task. Our methodology, PlugIR, actively utilizes the general instruction-following capability of LLMs in two ways. First, by reformulating the dialogue-form context, we elimina…

Rare Tokens Degenerate All Tokens: Improving Neural Text Generation via Adaptive Gradient Gating for Rare Token Embeddings

ACL 2022long

Recent studies have determined that the learned token embeddings of large-scale neural language models are degenerated to be anisotropic with a narrow-cone shape. This phenomenon, called the representation degeneration problem, facilitates an increase in the overall similarity between token embeddin…
