Interschool Lab (CEPSR 7th floor)
Speaker: Prof. Mihaela van der Schaar (University of California, Los Angeles)
Hosted by: Columbia University Joint CS/EE Networking Seminar Series
This talk proposes a new generation of ideas and technologies for designing the interactions between self-interested, learning agents in networked communities (social networks, servicenetworks, online labor markets, crowdsourcing, P2P networks). When the communities are composed of compliant machines (wireless nodes,routers, mobile phones etc.), network utility maximization (NUM) and other well-known control and optimization methods can be used to achieve efficient designs. When the communities are composed of intelligent and self-interested agents (people or smart softwareagents acting on their behalf), such methods are not effective and efficiency is much more difficult to achieve because the interests of the individual agents may be in conflict with that of the network designer. This talk describes design principles to achieve efficient outcomes in such networks based on the use of incentives (rewards and punishments). Depending on the characteristics of the network, the community, and the capacity of the designer, the application of these principles may be through any of a number of various mechanisms. This talk discusses mechanisms based on indirect reciprocation (socialnorms and token exchanges).
