LayoutLM-Byne-v0.1
The new SOTA in page retrieval from visually-rich documents.

We're glad to introduce one of the first document page embedding models, LayoutLM-Byne-v0.1.
With the rise of multimodal LLMs, there is a growing adoption of applying models directly to a document without pre-processing it first, as was done before with RAG. This approach is significantly more robust than text-only RAG on a large subset of documents, especially visually rich ones.
On the other hand, there is a significant lack of research focused on extracting a relevant page from a PDF or a DOCX document. Most practitioners would parse the page into text and apply regular text embeddings to the text, losing much positional context in the process.
LayoutLM [1] is an excellent solution for the problems because, at its core, it is a regular BERT-alike model, but it is uniquely capable of embedding positional information about the text alongside the text itself.
We have fine-tuned the model on the DocVQA [2] dataset, showing the potential improvement upon the current SOTA [4]:
| Model | HR@3 | HR@5 | HR@10 |
|---|---|---|---|
| all-mpnet-base-v2 | 0.2500 | 0.2900 | 0.3600 |
| gte-base-en-v1.5 | 0.3454 | 0.3899 | 0.4554 |
| snowflake-arctic-embed-m-v1.5 | 0.3548 | 0.4042 | 0.4573 |
| LayoutLM-Byne (our model) | 0.3491 | 0.4269 | 0.5436 |
| Improvement over best competitor | -1.61% | +5.62% | +18.87% |
