Contextual Games: Multi-Agent Learning with Side Information
Pier Giuseppe Sessa, Ilija Bogunovic, Andreas Krause +1
We formulate the novel class of contextual games, a type of repeated games driven by contextual information at each round. By means of kernel-based regularity assumptions, we model…
No-Regret Learning from Partially Observed Data in Repeated Auctions
Orcun Karaca, Pier Giuseppe Sessa, Anna Leidi +1
We study a general class of repeated auctions, such as the ones found in electricity markets, as multi-agent games between the bidders. In such a repeated setting, bidders can adap…
Bounding Inefficiency of Equilibria in Continuous Actions Games using Submodularity and Curvature
Pier Giuseppe Sessa, Maryam Kamgarpour, Andreas Krause
Games with continuous strategy sets arise in several machine learning problems (e.g. adversarial learning). For such games, simple no-regret learning algorithms exist in several ca…
Designing Coalition-Proof Reverse Auctions over Continuous Goods
Orcun Karaca, Pier Giuseppe Sessa, Neil Walton +1
This paper investigates reverse auctions that involve continuous values of different types of goods, general nonconvex constraints, and second stage costs. We seek to design the pa…
Exploring Vickrey-Clarke-Groves Mechanism for Electricity Markets
Pier Giuseppe Sessa, Neil Walton, Maryam Kamgarpour
Control reserves are power generation or consumption entities that ensure balance of supply and demand of electricity in real-time. In many countries, they are operated through a m…
