// 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.
