CNN. A neural network using convolutional operations to process structured local patterns. Weight sharing and locality help exploit spatial structure. For example: An image network slides learned filters across pixels.

Explore this concept

A useful analogy

A reusable detector scanning local regions rather than learning a new detector at every location.

Why it matters

This helps you interpret feature shapes and spatial behavior in image networks.

Technical detail

Convolutional layers share spatial kernel parameters. Stacking layers and downsampling change channel counts and receptive fields.

Common misconception

Weight sharing does not make a CNN perfectly invariant to every translation.
