// MODEL OPTIMIZATION AND PROMPT SYNTAX TERM

Feature Vector

A list of numerical values that represents a single data point or observation, where each value corresponds to a specific feature.

TECHNICAL DEFINITION

An ordered list or array of numerical values, where each element corresponds to a specific feature, collectively representing a single data instance or observation in a multi-dimensional feature space, serving as input to machine learning algorithms.

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.
