Abstract:

In a score aggregation system, several agents give scores to a set of candidates independently, and we are going to combine the individual scores to get a final score for each candidate. This is a fundamental problem with a broad range of applications in social choice and many other areas. The simple and commonly used method is to sum up (or average) all scores of each candidate. In this talk, we will give good algebraic and geometric explanations for score aggregation, and introduce a new aggregation model based on the spectral method.

Some results of this talk were published on IJCAI 2017 and AAMAS 2018.
