The Grind Behind the Epiphany: A Short Story of a Research Project
From ideation to outcome, this is the story of a privacy-preserving research project. It tells how research can generate innovations but also joy and despair. Early 2024: The “Hammer” Phase Two research leads who pioneered Criteo’s early privacy initiatives, as part of the Criteo multi-year research program, introduced me to a challenge born from the Privacy…

Agentic AI Symposium 2026
A science‑fueled, multidisciplinary approach to Agentic AI Authors: Jean-Yves Franceschi & Mariia Vladimirova At the Criteo AI Lab, we believe that making AI both trustworthy and useful requires a continuous and open dialogue between scientists, engineers, policymakers, regulators, and industry leaders. As AI systems evolve from passive predictors to agentic systems capable of planning, using tools,…

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…

Pareto-Optimality, Smoothness, and Stochasticity in Learning-Augmented One-Max-Search
A rule for choosing when to sell/buy an asset when facing a sequence of prices This Research Card explains a rule for choosing when to sell/buy an asset when facing a sequence of prices. The key feature is that the algorithm has access to “predictions” on the optimal price. The objectives are to take “safe” decisions,…
