简介

Donut-base-finetuned-docvqa 是由 Naver Clova 开发的一款端到端文档问答模型。它最大的特点是抛弃了传统的 OCR 预处理步骤,直接通过视觉编码器理解文档图像并生成文本答案,有效解决了 OCR 识别错误导致的信息丢失问题。对于需要从发票、表单或扫描件中快速提取特定信息的开发者来说,它提供了一种更简洁的 Pipeline。上手难度较低,适合作为文档自动化处理的轻量级方案,可与 LangChain 等框架结合构建本地知识库。

核心亮点

  • 端到端视觉理解,无需依赖第三方 OCR 引擎
  • 专注于文档问答,精准提取图像内关键信息
  • MIT 协议开源,部署灵活且商业化成本低
  • 简化处理流程,显著降低文档解析的链路复杂度

Donut (base-sized model, fine-tuned on DocVQA)

Donut model fine-tuned on DocVQA. It was introduced in the paper OCR-free Document Understanding Transformer by Geewok et al. and first released in this repository.

Disclaimer: The team releasing Donut did not write a model card for this model so this model card has been written by the Hugging Face team.

Model description

Donut consists of a vision encoder (Swin Transformer) and a text decoder (BART). Given an image, the encoder first encodes the image into a tensor of embeddings (of shape batch_size, seq_len, hidden_size), after which the decoder autoregressively generates text, conditioned on the encoding of the encoder.

Intended uses & limitations

This model is fine-tuned on DocVQA, a document visual question answering dataset.
