Dear faculty and students,<br>
<br>
We look forward to seeing you this Tuesday, August 29, at noon in NSH 1507<br>
(subject to change) for AI lunch. To learn more about the seminar and<br>
lunch, please visit the AI Lunch webpage <<a href="http://www.cs.cmu.edu/~aiseminar/" rel="noreferrer" target="_blank">http://www.cs.cmu.edu/~<wbr>aiseminar/</a>><br>

<br>
On Tuesday, Jason Hartline <<a href="https://sites.northwestern.edu/hartline/" rel="noreferrer" target="_blank">https://sites.northwestern.<wbr>edu/hartline/</a>> from<br>
Northwestern will visit CMU. If you want to meet him, please sign up in<br>
this spreadsheet<br>
<<a href="https://docs.google.com/spreadsheets/d/1iAtFpEjGcXSip8EFbMvJi6LARtyKbjmhn0HAqh7aLgw/edit#gid=0" rel="noreferrer" target="_blank">https://docs.google.com/<wbr>spreadsheets/d/<wbr>1iAtFpEjGcXSip8EFbMvJi6LARtyKb<wbr>jmhn0HAqh7aLgw/edit#gid=0</a>>.<br>
His talk is the following:<br>
<br>
Title: Peer Grading and Mechanism Design<br>
<br>
Abstract:<br>
<br>
The first part of the talk will overview a peer grading system that is<br>
under development at Northwestern U. In courses that use the system it has<br>
(a) reduced the grading load of course staff by over 75%, (b) expanded and<br>
improved the students??? interaction with the course material, (c) and<br>
improved turn-around time of feedback on student work (students receive<br>
comments on their work after three days, rather than two weeks). As a<br>
research platform, this system enables a dialogue between theory and<br>
practice for algorithms, machine learning, and mechanism design.<br>
<br>
Of particular focus for the talk is a connection between incentivizing<br>
students to give accurate peer reviews and all-pay position auctions.<br>
All-pay auctions are a common model for competitions based on effort. In an<br>
all-pay position auction, bidders compete for positions, where higher<br>
positions are more valuable, and all bidders pay their bids (i.e., their<br>
effort is spent). The equilibrium outcome of an all-pay auction depends on<br>
the relative values of the positions. The second part of the talk will<br>
describe recent work on reoptimizing all-pay position auctions from their<br>
equilibrium bid data.<br>
<br>
The second part of the talk is joint work with Shuchi Chawla and Denis<br>
Nekipelov.<br>
<br>
Bio: Prof. Hartline received his Ph.D. in 2003 from the University of<br>
Washington under the supervision of Anna Karlin. He was a postdoctoral<br>
fellow at Carnegie Mellon University under the supervision of Avrim Blum;<br>
and subsequently a researcher at Microsoft Research in Silicon Valley. He<br>
joined Northwestern University in 2008 where he is an associate professor<br>
of computer science. He was on sabbatical at Harvard University in the<br>
Economics Department during the 2014 calendar year and visiting Microsoft<br>
Research, New England for the Spring of 2015.<br>
