CODES Benchmark

🎉 Accepted to the ML4PS workshop @ NeurIPS 2024

Benchmark coupled ODE surrogate models on curated datasets with reproducible training, evaluation, and visualization pipelines. CODES helps you answer: Which surrogate architecture fits my data, accuracy target, and runtime budget?

What you get

• Baseline surrogates (MultiONet, FullyConnected, LatentNeuralODE, LatentPoly) with configurable hyperparameters
• Rich datasets spanning chemistry, astrophysics, and dynamical systems
• Optional studies for interpolation/extrapolation, sparse data regimes, uncertainty estimation, and batch scaling
• Automated reporting: accuracy tables, resource usage, gradient analyses, and dozens of diagnostic plots

Two-minute quickstart

uv (recommended)

git clone https://github.com/robin-janssen/CODES-Benchmark.git
cd CODES-Benchmark
uv sync                       # creates .venv from pyproject/uv.lock
source .venv/bin/activate
uv run python run_training.py --config configs/train_eval/config_minimal.yaml
uv run python run_eval.py --config configs/train_eval/config_minimal.yaml

pip alternative

git clone https://github.com/robin-janssen/CODES-Benchmark.git
cd CODES-Benchmark
python -m venv .venv && source .venv/bin/activate
pip install -e .
pip install -r requirements.txt
python run_training.py --config configs/train_eval/config_minimal.yaml
python run_eval.py --config configs/train_eval/config_minimal.yaml

Outputs land in trained/<training_id>, results/<training_id>, and plots/<training_id>. The configs/ folder contains ready-to-use templates (train_eval/config_minimal.yaml, config_full.yaml, etc.). Copy a file there and adjust datasets/surrogates/modalities before running the CLIs.

Documentation

• Main docs & tutorials
• API reference (Sphinx)
• Paper on arXiv

The GitHub Pages site now hosts the narrative guides, configuration reference, and interactive notebooks alongside the generated API docs.
