**TLDR:** The structure in which representations become increasingly abstract from lower to higher layers.

<p>Feature hierarchy is one of the most powerful representational ideas in deep learning. Lower layers often learn simpler structures such as edges, textures, or local patterns, while higher layers move toward objects, concepts, or semantic structure. This multi-level representation logic enables deep networks to extract strong features automatically from raw data. It is one of the main foundations of model success in computer vision and language processing.</p>
