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…
