Abstract

Many platforms need to promote users to invest effort in submitting accurate opinions; e.g., online product-rating platforms, votes on content curated on crowdsourcing platforms, and peer grading in massive open online courses (MOOCs). Frequently, it is important to align incentives towards informative inputs without access to gold standard answers. Peer prediction looks to address this problem by leveraging correlations between reports to make payments that promote effort and accuracy. However, classical solutions either require too much knowledge on the part of the mechanism designer or are otherwise fragile. In this talk, I will describe progress that we have made in the past few years on making peer prediction mechanisms more robust and better suited to practice.  --Joint work with Jens Witkowski.
