Attention

A mechanism that lets neural networks focus on the most relevant parts of their input when producing output.

Definition

A mechanism that lets neural networks focus on the most relevant parts of their input when producing output. Instead of treating all input equally, attention assigns different weights to different parts. The 'Attention Is All You Need' paper introduced the transformer architecture built entirely on this idea.
