# Valohai Parameter Migration

Migrate hardcoded values in ML code to Valohai-managed parameters. Parameters cover both **hyperparameters** (learning rate, epochs, batch size) and **configuration values** (model name, output format, feature flags, thresholds, file paths). This makes jobs configurable without code changes, enables experiment tracking, hyperparameter sweeps, and reproducibility.
