Deep learning

Deep learning is a subcategory of machine learning that utilizes artificial neural networks with multiple (more than a few hundreds as of 2024) hidden layers. The term "deep" implies the depth of the hidden layer.

Compared to general machine learning methods, deep learning typically requires a large amount of data and high computer power. Also, neural networks often act as the "black box", making it difficult to understand how they arrive at specific outputs. In contrast, general machine learning models are typically more interpretable.

Definitions in the literature

• Deep learning, a recently introduced branch of machine learning, applies a system of artificial neural networks (ANNs) with several hidden layers that compute a transformation of the underlying data that result in an output layer associated with a class [1].
