Architecture

Definition

Layers in a neural network between input and output that learn intermediate representations.

Hidden layers extract increasingly abstract features. Deep networks have many hidden layers. The term 'hidden' refers to not being directly observable as input or output.

Examples

Multiple hidden layers in deep networks

Feature extraction layers

Representation learning

Related Terms

Neural Network

A computational model inspired by biological neural networks, consisting of interconnected nodes (neurons) that process information.

Deep Learning

A subset of machine learning using neural networks with multiple layers to learn hierarchical representations of data.
