Let Language Constrain Geometry: Vision–Language Models as Semantic and Spatial Critics for 3D Generation

ICML 2026poster

Text-to-3D generation has advanced rapidly, yet state-of-the-art models, encompassing both optimization-based and feed-forward architectures, still face two fundamental limitations. First, they struggle with coarse semantic alignment, often failing to capture fine-grained prompt details. Second, the…

Time-To-Inconsistency: A Survival Analysis of Large Language Model Robustness to Adversarial Attacks

ICLR 2026poster

Large Language Models (LLMs) have revolutionized conversational AI, yet their robustness in extended multi-turn dialogues remains poorly understood. Existing evaluation frameworks focus on static benchmarks and single-turn assessments, failing to capture the temporal dynamics of conversational degra…

CLIP is Almost All You Need: Towards Parameter-Efficient Scene Text Retrieval without OCR

CVPR 2025poster

Scene Text Retrieval (STR) seeks to identify all images containing a given query string. Existing methods typically rely on an explicit Optical Character Recognition (OCR) process of text spotting or localization, which is susceptible to complex pipelines and accumulated errors. To settle this, we r…

Firm or Fickle? Evaluating Large Language Models Consistency in Sequential Interactions

ACL 2025finding

Large Language Models (LLMs) have shown remarkable capabilities across various tasks, but their deployment in high-stake domains requires consistent and coherent behavior across multiple rounds of user interaction. This paper introduces a comprehensive framework for evaluating and improving LLM resp…

Towards Natural Language-Based Document Image Retrieval: New Dataset and Benchmark

CVPR 2025poster

Document image retrieval (DIR) aims to retrieve document images from a gallery according to a given query. Existing DIR methods are primarily based on image queries that retrieve documents within the same coarse semantic category, e.g., newspapers or receipts. However, these methods struggle to effe…
