Amir Sani, PhD

Thank you for visiting my site.

My research interests are on the crossroads of machine learning, resource allocation and macroeconomic forecasting. In particular, I am interested in time-varying forecast combinations, online surrogate modeling, conformal regression and high-dimensional sampling. My current research,

  • attempts to address the Lucas Critique by calibrating macroeconomic agent-based models to real (eventually microfoundation) data. As part of this work, I have designed a high-dimensional sampling algorithm that enhances online surrogate modeling, which minimize the evaluations of costly simulators.
  • establishes an information theoretic dependent data Bootstrap for the most general class of dependent data processes possible (only assuming that the processes are Stationary-Ergodic). This allows for Monte-Carlo simulations, statistical analysis and Bootstrapping of highly dependent series, such as those produced by decision-making processes (e.g. online optimization/learning) and information cascades.

  • provides an online optimization algorithm that allows one to test a new decision-making policy, while avoiding the risk of underperforming an existing policy by more than a known constant. Further, the same algorithm allows one to combine a pool of heterogeneous forecasts into a point forecast that can be leveraged with the safety of never performing worse than the existing policy, or the difficult to outperform mean combination (also referred to as the so-called "forecast combination puzzle").


I am a postdoctoral research fellow working with Antoine Mandel at the Centre d'Économie de la Sorbonne, Université Paris 1, Panthéon-Sorbonne, Paris School of Economics. My research is part of the European Union Horizons 2020 Future and Emerging Technologies Distributed Global Financial Systems for Society (DOLFINS) project, which addresses the global challenge of making the financial system better serve society.

I am also an an External Researcher at the CFM Imperial Institute of Quantitative Finance, Visiting Professor at HEC Paris, Visting Professor at the University of Paris II Panthéon-Assas, Affiliate Researcher at School of Advanced Studies Pisa and an Associate Researcher at RiskLab Finland.

I completed my PhD, Machine Learning for Decision Making Under Uncertainty, under the supervision of Rémi Munos and Alessandro Lazaric at INRIA-Lille Nord Europe as part of the SequeL team.
