Deep learning architectures

Definition

Deep learning architectures are structured frameworks used in machine learning, particularly neural networks, designed to model complex patterns in data. These architectures consist of multiple layers of nodes that transform input data into a desired output, making them essential for tasks such as image recognition and natural language processing. Their ability to learn hierarchical representations allows for improved accuracy and efficiency in analyzing large datasets.
