Many defense methods require modifying model architectures during evaluation or performing test-time data purification. This not only introduces additional complexity but is often architecture-dependent. We show, however, that robust feature learning during training can significantly enhance DNN robustness. We propose MOREL, a multi-objective approach that aligns natural and adversarial features using cosine similarity and multi-positive contrastive losses to encourage similar features for same-class inputs. Extensive experiments demonstrate that MOREL significantly improves robustness against both white-box and black-box attacks. Our code is available at https://github.com/salomonhotegni/MOREL.","lang":"eng"}],"language":[{"iso":"eng"}],"doi":"10.1007/978-3-032-04558-4_35","year":"2026","title":"Enhancing Adversarial Robustness Through Multi-objective Representation Learning","publication_identifier":{"isbn":["978-3-032-04558-4"]},"author":[{"full_name":"Hotegni, Sedjro Salomon","first_name":"Sedjro Salomon","last_name":"Hotegni","id":"97995"},{"full_name":"Peitz, Sebastian","first_name":"Sebastian","last_name":"Peitz","orcid":"0000-0002-3389-793X","id":"47427"}],"date_updated":"2026-10-01T11:53:46Z","place":"Cham","citation":{"bibtex":"@inproceedings{Hotegni_Peitz_2026, place={Cham}, title={Enhancing Adversarial Robustness Through Multi-objective Representation Learning}, DOI={<a href=\"https://doi.org/10.1007/978-3-032-04558-4_35\">10.1007/978-3-032-04558-4_35</a>}, booktitle={Artificial Neural Networks and Machine Learning – ICANN 2025}, publisher={Springer Nature Switzerland}, author={Hotegni, Sedjro Salomon and Peitz, Sebastian}, editor={Senn, Walter and Sanguineti, Marcello and Saudargiene, Ausra and Tetko, Igor V. and Villa, Alessandro E.
