Researchers have developed a new approach to refreshing machine learning models trained on data that becomes outdated over time. They propose that instead of using a single, global staleness score to trigger retraining, models should refresh segments of their data differentially. This method, which involves allocating refresh intervals based on each segment's risk and cost, has been shown in simulations to reduce stale exposure by 8-29% compared to uniform timers, even with noisy rate estimations.
