Dec 14, 2024 · 6 min read · TL; DR by carefully selecting where to put aliasing mitigation in a CNN it is possible to limit anti-aliasing information loss. Aliasing negatively impact performances in a way that is not evident from validation loss. Another paper on the effect of ...
Join discussionDec 8, 2024 · 4 min read · The last two posts (1, 2) I published were on the topic of spatial robustness, i.e. the stability of a neural network prediction with respect to small translation and rotation. A curious observation from [1] states that first order adversary seem to ...
