// MODEL OPTIMIZATION AND PROMPT SYNTAX TERM
Model Validation
Checking how well a trained model performs on new, unseen data to ensure it's reliable.
TECHNICAL DEFINITION
The process of assessing a trained machine learning model's performance and generalization ability on an independent dataset (validation set) to estimate its effectiveness on future, unseen data and prevent overfitting.
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.
