softmax

This term is highly specialized, appearing almost exclusively in the fields of machine learning, deep learning, and statistics. It describes a specific operation used to normalize a set of numbers into a probability distribution, making it indispensable for multi-class classification tasks where a model must choose one category out of several mutually exclusive options.

When used as an adjective, it typically modifies nouns like "function," "layer," or "activation." While the noun form refers to the mathematical operation itself, the adjective form describes the architectural component of a neural network that implements this operation. It is a technical term with a neutral, descriptive connotation and is used across both academic research and industrial software engineering.
