Study reveals incremental learning is key for ML model retraining under drift

A new study on arXiv investigates the effectiveness of different machine learning model retraining strategies in production environments experiencing concept drift. The research found that the most significant factor influencing performance was whether the model learned incrementally, rather than the specific retraining policy employed. When models did not learn incrementally, periodic retraining outperformed reactive policies in most scenarios, though reactive policies showed an advantage under recurring drift. The study also highlighted issues with latency-budget interactions that can halve effective retraining budgets. AI
