Escaping Low-Rank Traps: Interpretable Visual Concept Learning via Implicit Vector Quantization

ICLR 2026poster

Concept Bottleneck Models (CBMs) achieve interpretability by interposing a human-understandable concept layer between perception and label prediction. The foundation of CBMs lies in the many-to-many mapping that translates high-dimensional visual features to a set of discrete concepts. However, we…

S2-UniSeg: Fast Universal Agglomerative Pooling for Scalable Segment Anything Without Supervision

AAAI 2026technical

Recent self-supervised image segmentation models have achieved promising performance on semantic segmentation and class-agnostic instance segmentation. However, their pretraining schedule is multi-stage, requiring a time-consuming pseudo-masks generation process between each training epoch. This

Minimizing Disparities between Real and Pseudo Queries for Unsupervised Visual Grounding

ICASSP 2025accepted

Visual grounding involves the identification and localization of image regions given textual descriptions. To reduce the manual labeling effort on region-text pairs, unsupervised visual grounding aims to generate pseudo bounding box and query pairs for training grounding models. However, there exist…

RoBGuard: Enhancing LLMs to Assess Risk of Bias in Clinical Trial Documents

COLING 2025main

Randomized Controlled Trials (RCTs) are rigorous clinical studies crucial for reliable decision-making, but their credibility can be compromised by bias. The Cochrane Risk of Bias tool (RoB 2) assesses this risk, yet manual assessments are time-consuming and labor-intensive. Previous approaches have…

Large Language Models are Complex Table Parsers

EMNLP 2023long main

With the Generative Pre-trained Transformer 3.5 (GPT-3.5) exhibiting remarkable reasoning and comprehension abilities in Natural Language Processing (NLP), most Question Answering (QA) research has primarily centered around general QA tasks based on GPT, neglecting the specific challenges posed by C…
