DEED: Dynamic Early Exit on Decoder for Accelerating Encoder-Decoder Transformer Models

NAACL 2024findings

Encoder-decoder transformer models have achieved great success on various vision-language (VL) and language tasks, but they suffer from high inference latency. Typically, the decoder takes up most of the latency because of the auto-regressive decoding. To accelerate the inference, we propose an appr…

DocKD: Knowledge Distillation from LLMs for Open-World Document Understanding Models

EMNLP 2024main

Visual document understanding (VDU) is a challenging task that involves understanding documents across various modalities (text and image) and layouts (forms, tables, etc.). This study aims to enhance generalizability of small VDU models by distilling knowledge from LLMs. We identify that directly p…

Enhancing Vision-Language Pre-training with Rich Supervisions

CVPR 2024highlight

We propose Strongly Supervised pre-training with ScreenShots (S4) - a novel pre-training paradigm for Vision-Language Models using data from large-scale web screenshot rendering. Using web screenshots unlocks a treasure trove of visual and textual cues that are not present in using image-text pairs.…

Multiple-Question Multiple-Answer Text-VQA

NAACL 2024industry

We present Multiple-Question Multiple-Answer (MQMA), a novel approach to do text-VQA in encoder-decoder transformer models. To the best of our knowledge, almost all previous approaches for text-VQA process a single question and its associated content to predict a single answer. However, in industry…

No Head Left Behind – Multi-Head Alignment Distillation for Transformers

AAAI 2024technical

Knowledge distillation aims at reducing model size without compromising much performance. Recent work has applied it to large vision-language (VL) Transformers, and has shown that attention maps in the multi-head attention modules of vision-language Transformers contain extensive intra-modal and cro…

DocTr: Document Transformer for Structured Information Extraction in Documents

ICCV 2023poster

We present a new formulation for structured information extraction (SIE) from visually rich documents. We address the limitations of existing IOB tagging and graph-based formulations, which are either overly reliant on the correct ordering of input text or struggle with decoding a complex graph. Ins…

PolyFormer: Referring Image Segmentation As Sequential Polygon Generation

CVPR 2023poster

In this work, instead of directly predicting the pixel-level segmentation masks, the problem of referring image segmentation is formulated as sequential polygon generation, and the predicted polygons can be later converted into segmentation masks. This is enabled by a new sequence-to-sequence framew…

End-to-End Piece-Wise Unwarping of Document Images

ICCV 2021poster

Document unwarping attempts to undo the physical deformation of the paper and recover a 'flatbed' scanned document-image for downstream tasks such as OCR. Current state-of-the-art relies on global unwarping of the document which is not robust to local deformation changes. Moreover, a global unwarpin…

LayoutTransformer: Layout Generation and Completion With Self-Attention

ICCV 2021poster

We address the problem of scene layout generation for diverse domains such as images, mobile applications, documents, and 3D objects. Most complex scenes, natural or human-designed, can be expressed as a meaningful arrangement of simpler compositional graphical primitives. Generating a new layout or…

Visual Relationship Detection Using Part-and-Sum Transformers With Composite Queries

ICCV 2021poster

Computer vision applications such as visual relationship detection and human object interaction can be formulated as a composite (structured) set detection problem in which both the parts (subject, object, and predicate) and the sum (triplet as a whole) are to be detected in a hierarchical fashion.…

VLAD3: Encoding Dynamics of Deep Features for Action Recognition

CVPR 2016poster

Previous approaches to action recognition with deep features tend to process video frames only within a small temporal region, and do not model long-range dynamic information explicitly. However, such information is important for the accurate recognition of actions, especially for the discrimination…
