max pooling does not provide anti-aliasing capability

  • from striding!!
  • recall signal processing: blur before max-pooling
    • max pooling -> maxing and subsampling
    • solution: maxing and blurring and subsampling
    • accuracy and shift-equivariance improves at the same time
      • and rotation-equivariance
