Aliasing and Sinc Artifact Free Pooling in the Fourier Domain","summary":"Researchers show that CNN downsampling layers violate the Sampling Theorem, and that this aliasing correlates with vulnerability to adversarial attacks and distribution shifts. They propose Frequency Low Cut Pooling (FLC Pooling) and its extension Aliasing and Sinc Artifact-free Pooling (ASAP), an alias-free downsampling operation in the frequency domain that also removes sinc-interpolation artifacts. On ImageNet-1k, ImageNet-C and CIFAR across several CNN architectures, networks using these methods showed greater robustness to common corruptions and adversarial attacks while keeping clean accuracy close to baseline models.","solution":"N/A -- no mitigation discussed in source.","labels":["security","research"],"sourceUrl":"https://doi.org/10.1007/s11263-026-03005-9","publishedAt":"2026-10-01T00:00:00.000Z","cveId":null,"cweIds":null,"cvssScore":null,"cvssSeverity":null,"severity":"info","attackType":[],"issueType":"research","affectedPackages":null,"affectedPackageNames":null,"affectedPackageRefs":null,"affectedVendors":[],"affectedVendorsRaw":[],"classifierModel":"claude-haiku-5-5","classifierPromptVersion":"v4","summaryPromptVersion":"v2","headline":null,"headlinePromptVersion":null,"cvssVector":null,"attackVector":null,"attackComplexity":null,"privilegesRequired":null,"userInteraction":null,"exploitMaturity":null,"epssScore":null,"epssCheckedAt":null,"kevDateAdded":null,"advisoryAliases":null,"affectedPackagesSource":null,"affectedPackagesCheckedAt":null,"patchAvailable":null,"disclosureDate":"2026-10-01T00:00:00.000Z","capecIds":null,"crossRefCount":0,"attackSophistication":"moderate","impactType":["integrity"],"aiComponentTargeted":"model","llmSpecific":false,"classifierConfidence":0.8,"researchCategory":"peer_reviewed","atlasIds":null}}
