What is the term for the decline in model accuracy over time caused by real-world changes not present in the training data?

Answer

Model drift

Model drift occurs when deployed models degrade in accuracy over time because real-world conditions change (e.g., widespread adoption of rooftop solar), necessitating monitoring and retraining.
