Comparing EvoVLM-JP w/ Existing VLMs

For details on the evaluation, please see Section 4.2 of the paper.

Model	JA-VG-VQA-500 (ROUGE-L ↑)	JA-VLM-Bench-In-the-Wild (ROUGE-L ↑)
LLaVA-1.6-Mistral-7B	14.32	41.10

EvoVLM-JP-v1-7B	19.70	51.25

• *1: Japanese Stable VLM cannot be evaluated using the JA-VG-VQA-500 dataset because this model has used this dataset for training.

Reproducing the Evaluation

1. Clone the Repo

git clone https://github.com/SakanaAI/evolutionary-model-merge.git
cd evolutionary-model-merge

2. Download fastext Model

We use fastext to detect language for evaluation. Please download lid.176.ftz from this link and place it in your current directory. If you place the file in a directory other than the current directory, specify the path to the file using the LID176FTZ_PATH environment variable.

3. Install Libraries

pip install -e .

We conducted our tests in the following environment: Python Version 3.10.12 and CUDA Version 12.3. We cannot guarantee that it will work in other environments.

4. Run

To launch evaluation, run the following script with a certain config. All configs used for the paper are in configs.

python evaluate.py --config_path {path-to-config}

Acknowledgement

We would like to thank the developers of the source models for their contributions and for making their work available. Our math evaluation code builds on the WizardMath repository, and we are grateful for their work.
