报告题目：On Truth Finding in Multi-agent Networks
报 告 人：杨杰龙 博士
报告摘要：Aproblem named “truth finding” will be discussed in this talk. In this problem, an event is a phenomenon of interest and our goal is to infer the states of events (e.g., articles, movies, and signals) through biased observations of multiple agents (e.g., sensors and individuals) in a network. The local bias of each agent is unknown and affects the agent's observation of the event true states. The following three cases of the problem will be discussed: each sequence of events are temporally correlated, agents are nodes of a social network, and the observation of each event is a graph signal.
