Breaking bidder collusion in large-scale spectrum auctions
Xia Zhou,Haitao Zheng +1 more
TL;DR: Athena, a new collusion-resistant auction framework for large-scale dynamic spectrum auction, is proposed, which enables spectrum reuse across bidders, achieves soft collusion resistance against any form of collusive bidding strategy, maintains provable revenue guarantee, and does so with polynomial-time complexity.

SmartGPA: How Smartphones Can Assess and Predict Academic Performance of College Students
Book ChapterDOI
StudentLife: Using Smartphones to Assess Mental Health and Academic Performance of College Students
Rui Wang,Fanglin Chen,Zhenyu Chen,Tianxing Li,Gabriella M. Harari,Stefanie M. Tignor,Xia Zhou,Dror Ben-Zeev,Andrew T. Campbell +8 more
TL;DR: This work proposes a simple model based on linear regression with lasso regularization that can accurately predict cumulative GPA and identifies a Dartmouth term lifecycle in the data that shows students start the term with high positive affect and conversation levels, low stress, and healthy sleep and daily activity patterns.
Proceedings ArticleDOI
Empirical Validation of Commodity Spectrum Monitoring
TL;DR: The efforts to empirically validate a distributed spectrum monitoring system built on commodity smartphones and embedded low-cost spectrum sensors that enables real-time spectrum sensing, identifies and locates active transmitters, and generates alarm events when detecting anomalous transmitters.
