Reviving Shift Equivariance in Vision Transformers

no code implementations13 Jun 2023 Peijian Ding, Davit Soselia, Thomas Armstrong, Jiahao Su, Furong Huang

While the self-attention operator in vision transformers (ViT) is permutation-equivariant and thus shift-equivariant, patch embedding, positional encoding, and subsampled attention in ViT variants can disrupt this property, resulting in inconsistent predictions even under small shift perturbations.

Deep learning with photosensor timing information as a background rejection method for the Cherenkov Telescope Array

1 code implementation10 Mar 2021 Samuel Spencer, Thomas Armstrong, Jason Watson, Salvatore Mangano, Yves Renier, Garret Cotter

As the arrival times of Cherenkov photons from Extensive Air Showers (EAS) at the camera plane are dependent upon the altitude of their emission and the impact distance from the telescope, these waveforms contain information potentially useful for IACT event classification.
