FailureAtlas: Mapping the Failure Landscape of T2I Models via Active Exploration

CVPR 2026

Static benchmark-driven evaluation has provided a valuable foundation for analyzing Text-to-Image (T2I) models.However, the fixed and predetermined prompt sets in benchmarks inherently limit diagnostic depth, making it difficult to uncover the full landscape of models' systematic failures or isolate

GRAPE: Let GRPO Supervise Query Rewriting by Ranking for Retrieval

ICML 2026poster

The CLIP model has established itself as a cornerstone of large-scale retrieval systems. However, its performance often degrades under distributional shifts such as multilingual, long-form, or multimodal queries. To avoid the prohibitive costs associated with retriever retraining or corpus re-embedd…

HiBug2: Efficient and Interpretable Error Slice Discovery for Comprehensive Model Debugging

ICLR 2025poster

Despite the significant success of deep learning models in computer vision, they often exhibit systematic failures on specific data subsets, known as error slices. Identifying and mitigating these error slices is crucial to enhancing model robustness and reliability in real-world scenarios. In this…

DIFFGUARD: Semantic Mismatch-Guided Out-of-Distribution Detection Using Pre-Trained Diffusion Models

ICCV 2023poster

Given a classifier, the inherent property of semantic Out-of-Distribution (OOD) samples is that their contents differ from all legal classes in terms of semantics, namely semantic mismatch. There is a recent work that directly applies it to OOD detection, which employs a conditional Generative Adver…

HumanSD: A Native Skeleton-Guided Diffusion Model for Human Image Generation

ICCV 2023oral

Controllable human image generation (HIG) has attracted significant attention from academia and industry for its numerous real-life applications. State-of-the-art solutions, such as ControlNet and T2I-Adapter, introduce an additional learnable branch on top of the frozen pre-trained stable diffusion…
