Multimodal Chain-of-Thought Reasoning in Language Models

"Imagine learning a textbook without figures or tables."

Multimodal-CoT incorporates vision features in a decoupled training framework. The framework consists of two training stages: (i) rationale generation and (ii) answer inference. Both stages share the same model architecture but differ in the input and output.

Requirements

Install all required python dependencies:

pip install -r requirements.txt

Datasets

Download the dataset from the following repository:

https://github.com/lupantech/ScienceQA/tree/main/data

Download the extracted vision features from vision_features and unzip the files under vision_features

Instructions

Inference

Our trained models are available at models. To use our trained models, please put the them under the models folder.
