  • Generating the Ground Truth: Synthetic Data for Label Noise Research 
    Vries, Sjoerd de; Thierens, Dirk (arXiv, 2023-09-08)
    Most real-world classification tasks suffer from label noise to some extent. Such noise in the data adversely affects the generalization error of learned models and complicates the evaluation of noise-handling methods, as ...
  • Topological Monomodes in non-Hermitian Systems
