// MODEL OPTIMIZATION AND PROMPT SYNTAX TERM

Feature

An individual measurable property or characteristic of a phenomenon being observed, used as input to a machine learning model.

TECHNICAL DEFINITION

An individual, quantifiable attribute or variable (e.g., age, color, word count) derived from raw data, serving as an input dimension to a machine learning model for learning patterns and making predictions.

BACKGROUND

Prompt engineering is the process of structuring natural language inputs to produce specified outputs from a generative artificial intelligence (GenAI) model. Context engineering is the related area of software engineering that focuses on the management of non-prompt contexts supplied to the GenAI model, such as metadata, API tools, and tokens.
