摘要：Existing approaches to designing recommendation systems with user feedback focus on settings where the number of items is small and/or admit some underlying structure. It is unclear, however, if these approaches extend to applications like social network news feeds and content-curation platforms, which have large and unstructured content pools and constraints on user-item recommendations. To this end, we consider the design of recommendation systems in content-rich setting-where the number of ...

摘要：We consider a class of Nash games, termed as aggregative games, being played over a networked system. In an aggregative game, a player's objective is a function of the aggregate of all the players' decisions. Every player maintains an estimate of this aggregate, and the players exchange this information with their local neighbors over a connected network. We study distributed synchronous and asynchronous algorithms for information exchange and equilibrium computation over such a network. Under...

摘要：We study decentralized markets involving producers and consumers that are facilitated by middlemen. We do this by analyzing a noncooperative networked bargaining game. We assume a complete information setup wherein all the agents know the structure of the network, the values of the consumers, and the transaction costs involved but allow for some search friction when either producers or consumers trade with middlemen. In such a setting, we show that sunk cost problems and a heterogeneous networ...
