LLama 2 LLM for PDF Invoice Data Extraction

Показать описание

I show how you can extract data from text PDF invoice using LLama2 LLM model running on a free Colab GPU instance. I specifically explain how you can improve data retrieval using carefully crafted prompts.

LLM will fail to extract the correct information if the invoice layout is too complex. The OCR won't be able to read the text in proper order. The document must be segmented before passing to llm. How can this be done?

Can you explain how to PDF is turned to text and where it is fed to the LLM? I could not figure that out from the notebook.

Great and informative video Andrej, thank you. Do think it would be feasible to use this method to extract product data from a csv (description, category) and to make llama recommend products based on a users prompt?

i am confused here, that like we use to prepare/annotate data for Donut, here it is not required, we can take any invoice and use the notebook and write script it will extract data?

Anyway to get all the extracted information in a json format

Nice video! I also wanted to know if we can make faster a LLM model. I integrated it with a OCR tools to extract text and informations but it is actually very slow

Nice video! I am looking for a solution to extract data from pdf/image for production. Can I assume using OCR + LLM is more accurate than using Donut for extracting data from pdf/image?

Hello Andrej, thank you for your videos! They are absolutely marvellous and quite helpful. I was curious to know whether this LLAMA model could work with scanned documents such as bank cheques, especially when the quality isn't always top-notch. If not, could you recommend a model similar to LLAMA for extracting information from bank cheques? I'm currently using the Doctr model, but I'm keen to enhance the quality of extraction for my bank cheques.

Thanks for this very helpful content. Can you please give me suggestions on prompt engineering for parsing invoices to extraxt both table items and other non- table entities?

swathys

so it will not work with images? only scanned pdfS?

getting error: RuntimeError: Unexpected floating ScalarType in at::autocast::prioritize

akhiljx

are there any videos on image invoices?

Awesome! I didn't managed to get it running. There seems to be an issue with pydantic.

Anyone else facing this issue?
