Pareto-Optimal Fairness-Utility Amortizations in Rankings with a DBN Exposure Model
Till Kletti, Jean-Michel Renders, Patrick Loiseau
In recent years, it has become clear that rankings delivered in many areas need not only be useful to the users but also respect fairness of exposure for the item producers. We con…
Introducing the Expohedron for Efficient Pareto-optimal Fairness-Utility Amortizations in Repeated Rankings
Till Kletti, Jean-Michel Renders, Patrick Loiseau
We consider the problem of computing a sequence of rankings that maximizes consumer-side utility while minimizing producer-side individual unfairness of exposure. While prior work…
Selfish & Opaque Transaction Ordering in the Bitcoin Blockchain: The Case for Chain Neutrality
Johnnatan Messias, Mohamed Alzayat, Balakrishnan Chandrasekaran +3
Most public blockchain protocols, including the popular Bitcoin and Ethereum blockchains, do not formally specify the order in which miners should select transactions from the pool…
Modeling Coordinated vs. P2P Mining: An Analysis of Inefficiency and Inequality in Proof-of-Work Blockchains
Mohamed Alzayat, Johnnatan Messias, Balakrishnan Chandrasekaran +2
We study efficiency in a proof-of-work blockchain with non-zero latencies, focusing in particular on the (inequality in) individual miners' efficiencies. Prior work attributed diff…
Scalable Optimal Classifiers for Adversarial Settings under Uncertainty
Patrick Loiseau, Benjamin Roussillon
We consider the problem of finding optimal classifiers in an adversarial setting where the class-1 data is generated by an attacker whose objective is not known to the defender --…
Colonel Blotto Games with Favoritism: Competitions with Pre-allocations and Asymmetric Effectiveness
Dong Quan Vu, Patrick Loiseau
We introduce the Colonel Blotto game with favoritism, an extension of the famous Colonel Blotto game where the winner-determination rule is generalized to include pre-allocations a…
