// MODEL OPTIMIZATION AND PROMPT SYNTAX TERM

Decision Boundary

A line or surface that separates different classes or categories in a classification problem.

TECHNICAL DEFINITION

A hyperplane or manifold in the feature space that a classification algorithm learns to delineate regions corresponding to different class labels, effectively separating data points belonging to distinct categories.

BACKGROUND

A large language model (LLM) is a neural network trained on a vast amount of text for natural language processing tasks, especially language generation. LLMs can typically generate, summarize, translate and analyze text in many contexts, and are a foundational technology behind modern chatbots. Biased or inaccurate training data can make an LLM's output less reliable.
