A Critical Analysis of Document Out-of-Distribution Detection

EMNLP 2023long findings

Large-scale pre-training is widely used in recent document understanding tasks. During deployment, one may expect that models should trigger a conservative fallback policy when encountering out-of-distribution (OOD) samples, which highlights the importance of OOD detection. However, most existing OO…

MGDoc: Pre-training with Multi-granular Hierarchy for Document Image Understanding

EMNLP 2022main

Document images are a ubiquitous source of data where the text is organized in a complex hierarchical structure ranging from fine granularity (e.g., words), medium granularity (e.g., regions such as paragraphs or figures), to coarse granularity (e.g., the whole page). The spatial hierarchical relati…

Cross-Domain Document Object Detection: Benchmark Suite and Method

CVPR 2020poster

Decomposing images of document pages into high-level semantic regions (e.g., figures, tables, paragraphs), document object detection (DOD) is fundamental for downstream tasks like intelligent document editing and understanding. DOD remains a challenging problem as document objects vary significantly…
