ML models degrade as training data expires due to evolving real-world distributions

Machine learning models can degrade over time even without system failures, a phenomenon attributed to the "expiration" of their training data. This decay occurs because real-world data distributions evolve, making the original training datasets less representative. To combat this, continuous monitoring and retraining of models with updated data are essential for maintaining performance. AI
