: Deep learning models build these features in stages:
: Deep features are typically output as numerical vectors (a row of numbers) from the last fully connected or pooling layer before the final classification. Common Applications 78E0C7C5-B8A7-4FE7-A739-9592B5DB499F.jpeg
: Unlike traditional "handcrafted" features (such as color histograms or shape descriptors) that are designed by humans, deep features are learned automatically by the model during training. : Deep learning models build these features in

represent high-level concepts or objects (e.g., a "wheel" or a "face").
detect simple patterns like edges, textures, or blobs. Intermediate layers combine these into more complex shapes.
