Vision: sliding detectors and image tokens

Suggested preparation: Embeddings: useful coordinates for meaning

Picture it

A convolution slides the same small detector across an image. Early layers can respond to local patterns; later layers combine them. A vision transformer instead treats patches as tokens that exchange information.

What to understand

  • Convolution, receptive field, pooling, and translation bias
