Optimal Transport for Correctional Learning

no code implementations4 Apr 2023 Rebecka Winqvist, Inês Lourenco, Francesco Quinzan, Cristian R. Rojas, Bo Wahlberg

In this framework, an expert agent, referred to as the teacher, modifies the data used by a learning agent, known as the student, to improve its estimation process.

Learning Counterfactually Invariant Predictors

1 code implementation20 Jul 2022 Francesco Quinzan, Cecilia Casolo, Krikamol Muandet, Yucen Luo, Niki Kilbertus

Notions of counterfactual invariance (CI) have proven essential for predictors that are fair, robust, and generalizable in the real world.

Adaptive Sampling for Fast Constrained Maximization of Submodular Function

no code implementations12 Feb 2021 Francesco Quinzan, Vanja Doskoč, Andreas Göbel, Tobias Friedrich

Our algorithm is suitable to maximize a non-monotone submodular function under a $p$-system side constraint, and it achieves a $(p + O(\sqrt{p}))$-approximation for this problem, after only poly-logarithmic adaptive rounds and polynomial queries to the valuation oracle function.

Approximating Optimization Problems using EAs on Scale-Free Networks

no code implementations12 Apr 2017 Ankit Chauhan, Tobias Friedrich, Francesco Quinzan

It has been observed that many complex real-world networks have certain properties, such as a high clustering coefficient, a low diameter, and a power-law degree distribution.
