Description du poste
At Crédit Agricole Assurances, the Group Investment Department offers investment strategies to our various subsidiaries. It ensures their implementation and monitoring with a focus on acting in the best interest of society and our clients.
This internship is a joint project between the Quantitative Research team of Crédit Agricole Assurances and the CERMICS laboratory (École des Ponts ParisTech). The objective is to implement and evaluate a decision-focused learning (DFL) framework applied to portfolio optimization.
The traditional way of building an investment portfolio is a two-step process that separates parameter estimation from optimization :

Expected returns and dependence relationships (covariances) between assets are estimated
These estimates are plugged into a mathematical model, to find the optimal mix of assets accordingly to the objective

The main issue with this estimate-then-optimize" approach is that both steps are treated as separate tasks, leading to several issues, in
particular with multivariate time series data. The intership objective is to implement and evaluate a Decision-Focused Learning (DFL)
framework aiming to tackle the flaws of the traditional estimate, then optimize method. Instead, DFL core idea is to create a single,
end-to-end system that learns to make the best possible investment decisions directly from data.
Portfolio optimization often involves making discrete (combinatorial) choices. However, the mathematical methods typically used to train
neural networks work best with smooth, continuous problems, not discrete, combinatorial ones. A key challenge will be to bridge such
gap and identify the most suitable algorithm from the existing literature for training a network that include a combinatorial optimization
layer, specifically tailored to the unique uncertainties inherent in portfolio optimization.
Your internship mentor will support your integration and skill development.
