Apple researchers have developed Fortress, a framework designed to improve the stability and accuracy of search recommendation models. The system addresses temporal instability caused by volatile input features, which can degrade user experience. Fortress identifies and prunes features that lead to inconsistent prediction scores over time, particularly by mitigating the volatility of engagement-based features while preserving their predictive power.
