Hyperparameter — AI Glossary

A configuration value set before training (learning rate, batch size, LoRA rank) that governs the training process but is not learned from data.

Overview

Hyperparameters control how a model learns, contrasted with parameters (weights) which are learned. Key LLM hyperparameters: learning rate, warmup steps, weight decay, batch size, context length, LoRA rank/alpha, and dropout rate. Hyperparameter tuning methods: grid search, random search, Bayesian optimization (W&B Sweeps, Optuna). Poor hyperparameter choices can prevent convergence or cause overfitting.
