ViscNet is a machine learning model that can predict the temperature-dependency of viscosity of oxide liquids and the fragility index and the glass transition temperature.
Python 3.6-3.9 is required to run the code. The recommended procedure is to create a new virtual environment and install the necessary modules by running
pip install -r requirements.txt- models.py: class to build the models and function to train them.
- data.py: reads the data and splits it.
- train.py: train ViscNet, ViscNet-Huber, and ViscNet-VFT models.
- cross-validation.py: computes the cross-validation metrics.
- metrics.py: compute the metrics of the ViscNet, ViscNet-Huber, and ViscNet-VFT models.
- plots.py: generate the plots to check the performance of the models.
If you find bugs or have questions, please open an issue. PRs are most welcome.
