---
## Definition
**Dictionary learning** discovers a set of reusable components whose combinations reconstruct observed signals or activations. Sparse coding favors explanations using relatively few dictionary elements for each observation.
## Architectural role
The method provides one way to turn distributed internal geometry into inspectable features, enabling analysis or intervention without pretending the learned dictionary is the only valid decomposition.
