// MODEL OPTIMIZATION AND PROMPT SYNTAX TERM
Confusion Matrix
A table that summarizes the performance of a classification model by showing the counts of true positive, true negative, false positive, and false negative predictions.
TECHNICAL DEFINITION
A confusion matrix is a specific table layout that allows visualization of the performance of an algorithm, typically a supervised learning one, providing a breakdown of correct and incorrect predictions for each class.
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.
