This repository was used to develop AsymMirai. The codebase itself is a fork of the MIT-licensed Mirai codebase (https://github.com/yala/Mirai). Because AsymMirai also relies on the Mirai backbone, most of the Mirai code is retained in this repository. See README_mirai.md for details on the parts of the codebase original to Mirai.
AsymMirai was primarily trained and evaluated on the EMory BrEast imaging Dataset (EMBED); as such, it assumes the information described in the EMBED documentation is available. This dataset is available upon request; instructions to gain access are available in the EMBED documentation.
This implementation assumes there exists a CSV file of the form shown in example_data_format.csv with the path to each image and metadata for a series of exams.
The jupyter notebook asymmetry_model/run_train.ipynb provides an example of the call to train AsymMirai.
The jupyter notebook asymmetry_model/run_train.ipynb provides an example of the code used to evaluate a trained AsymMirai. This code runs AsymMirai over each exam in the indicated CSV file, and records the risk score and prediction window location for each sample.
The jupyter notebook asymmetry_model/run_train.ipynb provides the code used to analyze AsymMirai, producing ROC curves.
