Convolutional neural network (CNN)

A neural network built for spatial data like images, where each layer looks at a small neighbourhood of the input and global context only builds up in the deeper layers. CNNs are strong on local patterns but weaker at long-range relationships, which is part of why vision transformers are used as an alternative.
