LOOPE: Learnable Optimal Patch Order in Positional Embeddings for Vision Transformers
Md Abtahi Majeed Chowdhury, Md Rifat Ur Rahman, Akil Ahmad Taki
Positional embeddings (PE) play a crucial role in Vision Transformers (ViTs) by providing spatial information otherwise lost due to the permutation invariant nature of self attenti…
