## Public overview

Convolution is a recurring research-paper notation family. Combines a signal with a shifted kernel through repeated local multiply-and-sum operations across spatial or temporal positions.

Convolution: Combines a signal with a shifted kernel through repeated local multiply-and-sum operations across spatial or temporal positions. Example: At each output position, multiply a local input window by kernel weights and add.
