Introduction

Atomvision is a deep learning framework for atomistic image data.

Installation

First create a conda environment: Install miniconda environment from https://conda.io/miniconda.html Based on your system requirements, you'll get a file something like 'Miniconda3-latest-XYZ'.

Now,

bash Miniconda3-latest-Linux-x86_64.sh (for linux)
bash Miniconda3-latest-MacOSX-x86_64.sh (for Mac)

Download 32/64 bit python 3.6 miniconda exe and install (for windows) Now, let's make a conda environment, say "version", choose other name as you like::

conda create --name vision python=3.8
source activate vision

Now, let's install the package:

Method 1 (using setup.py):

git clone https://github.com/usnistgov/atomvision.git
cd atomvision
python setup.py develop

Method 2 (using pypi):

As an alternate method, AtomVision can also be installed using pip command as follows:

pip install atomvision

Examples

Generating STEM image with convolution approximation: graphene example

stem_conv.py --file_path atomvision/tests/POSCAR --output_path STEM.png

2D-Bravais lattice classification example

This example shows how to classify 2D-lattice (5 Bravais classes) for 2D-materials STM/STEM images.

We will use imagessample_data folder. It was generated with generate_stem.py script. There are two folders train_folder, test_folder with sub-folders 0,1,2,3,4,... for individual classes and they contain images for these classes.

train_classifier_cnn.py --model densenet --train_folder atomvision/sample_data/test_folder --test_folder atomvision/sample_data/test_folder --epochs 5 --batch_size 16

Generating a t-SNE plot

train_tsne.py --data_dir atomvision/sample_data/test_folder

Generative Adversarial Network

train_gan.py --dataset_path atomvision/sample_data/test_folder/0 --epochs 2

Autoencoder

train_autoencoder.py --train_folder atomvision/sample_data/test_folder --test_folder atomvision/sample_data/test_folder --epochs 10
