On the Impact of the Utility in Semivalue-based Data Valuation
A new diagnostic method that scores data valuation robustness for cleaning, efficient training, and fair partner compensation. This Research Card introduces a new way to measure how trustworthy data valuation really is, by checking how much rankings of “most valuable data” change when the performance metric changes. Using a geometric representation of data contributions, the…

Off-Policy Learning in Large Action Spaces
Optimization Matters More Than Estimation This Research Card shows that in large-scale recommendation systems, like those used at Criteo, focusing on how we optimize algorithms is more impactful than trying to perfectly estimate outcomes. By using simpler, more stable training objectives, we can achieve better click-through rates, faster experimentation, and more scalable performance across millions…
