How to fine-tune Llama models for structured extraction of data from images

Extracting data from images can be a challenge, but with Llama models, it doesn't have to be. In this tutorial, you'll learn how to fine-tune Llama 11B Vision Instruct to improve performance for image-to-JSON data extraction. We will go over how to customize and evaluate Llama models for this specific use case while preserving existing knowledge.

You’ll learn how to:

•
Extract structured data from images using vision models
•
Achieve performance improvements with minimal adjustments
•
Prepare and split datasets for model training
•
Evaluate base model performance
•
Understand model training configurations and their components
•
Verify that specialized training doesn't negatively impact general performance
