Python package to model and to perform topology optimization for graphene kirigami using deep learning. We use convolutional neural networks (similar to VGGNet architecure) for regression.

-
A python code to perform regression with TensorFlow is avalaible in
models/regression_CNN/tf_fgrid_dnn_validtrain.py
-
A jupyter notebook to generate atomic configurations for LAMMPS input file is avalaible in
generate_LAMMPS_input/generate_LAMMPS_configuration_input.ipynb
-
A simple jupyter notebook to perform predictions with scikit-learn package is avalaible in
models/simple/simple_machine_learning.ipynb
-
A simple jupyter notebook to convert coarse-grained dataset to fine-grid dataset is avalaible in
models/regression_CNN/convert_coarse_to_fine.ipynb
-
Raw dataset of coarse-grained grid can be found in
mddata
. This dataset generated using AIREBO potential with 1.7 mincutoff which is the default of CH.airebo.
This package is still under developement. More features (e.g., search algorithm with TensorFlow code) will be added soon.
