My experiments consistently underperform in comparison to the paper's reported results.

Although I followed the exact settings outlined in the reproducibility file, my experiments consistently yield inferior results compared to those reported in the paper. Any suggestions, recommendations, or additional details I might overlooked?

Unfortunately, it's been quite some time since I wrote the reproducibility file. However, there was a previous issue detailing certain problems with reproducibility and the user was able to match our results: #23.

Did you preprocess each fold separately using the provided script?

Thank you for your reply! I successfully reproduce the result after doing the features normalization.
