Dr. Alex Beutel and Prof. Evangelos (Vagelis) Papalexakis, each attracted the ‘runner-up’ distinction for the prestigious SIGKDD doctoral dissertation award. SIGKDD is the flagship venue for data mining. Alex’s dissertation, titled ‘User Behavior Modeling with Large-Scale Graph Analysis’ focused on anomaly detection, by modeling normal and abnormal users, as well as on the design of scalable algorithms for large graphs. Vagelis’ dissertation, titled 'Mining Large Multi-aspect Data: Algorithms and Applications' bridged signal- and tensor-analysis, with data mining at scale, and Read More

CMU team wins the ‘Test of Time’ award at KDD 2016 for their 2005 paper: Graphs Over Time: Densification Laws, Shrinking Diameters and Possible Explanations Jure Leskovec, Jon Kleinberg, and Christos Faloutsos KDD is the flagship conference for large-scale data mining. Jure was a phd student at SCS/MLD (and currently a professor at Stanford). Jon was visiting CMU for his sabbatical. The paper made the surprising discoveries that real graphs become denser over time, following a power-law pattern, and that Read More

SIAM SDM is one of the top conferences in data mining. Specifically, Vagelis  attracted the 'best student paper award', with his single-author paper on tensors   Evangelos E. Papalexakis, Automatic Unsupervised Tensor Mining with Quality Assessment There, Vagelis showed how to measure the goodness of a tensor decomposition, and how to automatically determine the correct rank of such a decomposition. Moreover, CMU/SCS alumna Prof. Leman Akoglu, and her student,  attracted the 'best  paper runner-up award' for their paper on anomaly Read More
