This is the repository for our paper titled "Motif-guided time series counterfactual explanations". This paper has been accepted at the Big Data Analytics and Knowledge Discovery 25th International Conference, DaWaK 2023
In this paper, we propose Attention-based Counterfactual Explanation (AB-CF), a novel model that generates post-hoc counterfactual explanations for multivariate time series classification that narrows the attention to a few important segments. We validated our model using seven real-world time-series datasets from the UEA repository. Our experimental results show the superiority of AB-CF in terms of validity, proximity, sparsity, contiguity, and efficiency compared with other competing state-of-the-art baselines.
The data used in this project comes from the UEA archive.
All python packages needed are listed in pip-requirements.txt file and can be installed simply using the pip command.
