+The generated dataset is now available. Data are on the `master` branch due to initial commit error.
+
+To use the data, each `.tar` package contains a `train`, `val`, `test` split. Move them to `./dataset`, then untar them.
+
+To train the model, provide the path(s) of the untarred folders to the training script. For detail, please check the code repository.
