Adapting Multimodal Large Language Models to Domains via Post-Training (EMNLP 2025)

This project adapts general Multimodal Large Language Models (MLLMs) to specific domains like science and industry to improve their real-world use. It focuses on three main areas:

1. Data Synthesis

We create a generate-then-filter pipeline using open-source models to make diverse visual tasks from domain-specific image-caption pairs.
This data works better than data made by hand or closed-source models (e.g., GPT-4V/o).

2. Training Pipeline

Instead of the usual two-step training (image-caption pairs first, then visual tasks), we use a single-stage training to handle more tasks for specific domains.

3. Task Evaluation

We test our method in high-impact domains like biomedicine, food, and remote sensing.
We train and evaluate MLLMs on domain-specific tasks to show how well they perform.
