Vision Transformer (An Image is Worth 16x16 Words)

Alexey Dosovitskiy, Lucas Beyer, Alexander Kolesnikov, et al.

Introduced the Vision Transformer, showing that a plain Transformer applied to fixed-size image patches can match or beat convolutional networks on image classification, removing the assumption that vision required convolution-specific inductive biases.

Editorial record

Plain-language summary

The model splits an image into a grid of small patches (e.g. 16x16 pixels), linearly embeds each patch as if it were a word token, adds position embeddings, and feeds the sequence into a standard Transformer encoder. With no convolutions, it learns spatial structure from data alone, which works well only when pre-trained on very large image datasets. This let the same architecture used for language be reused for vision and scaled up with more data and compute rather than hand-designed vision components.
