: Because deep features represent general high-level concepts, they are often "reused" for different tasks. For example, a model trained on general photos can have its deep features extracted to help classify more specific subjects, like medical images or fashion items.

While early layers of a network detect simple edges and textures, deeper layers capture abstract concepts such as specific objects (e.g., a "car" or "face"), complex patterns, and composition. How Deep Features Work

: As data passes through a network, it becomes increasingly abstract. Deep features represent the model's "understanding" of high-level semantic traits like shape, border definition, or texture.

: These features are typically stored as numeric vectors. They allow computers to compare images based on content rather than just raw pixels, which is essential for modern image search and recommendation systems.
