Transformers' intrusion detection gains questioned by evaluation methods

A new research paper questions the effectiveness of Transformer models in network intrusion detection systems. The study found that evaluation methodology, particularly padding conventions and data splitting, significantly impacts reported performance rather than the Transformer architecture itself. When evaluated under realistic, leakage-free conditions without padding, Transformers showed strong performance, but this advantage diminished significantly with common padding schemes, while other models remained stable.
