A new research paper questions the effectiveness of Transformer models in network intrusion detection, particularly on the CIC-IDS2017 dataset. The study found that evaluation methodology, specifically padding conventions and data splitting, significantly impacts reported performance, often overestimating the Transformer's capabilities. When evaluated under realistic, leakage-free conditions without padding, the Transformer's performance drops considerably, suggesting that architectural choices are less critical than rigorous evaluation practices.
