Classification of Passes in Football Matches using Spatiotemporal Data
Michael Horton, Joachim Gudmundsson, Sanjay Chawla +1
A knowledgeable observer of a game of football (soccer) can make a subjective evaluation of the quality of passes made between players during the game. We investigate the problem o…
Resilience of human brain functional coactivation networks under thresholding
S. Sarkar, S. Chawla, H. Weng
Recent studies have demonstrated the existence of community structure and rich club nodes, (i.e., highly interconnected, high degree hub nodes), in human brain functional networks.…
Integer Programming Relaxations for Integrated Clustering and Outlier Detection
Lionel Ott, Linsey Pang, Fabio Ramos +2
In this paper we present methods for exemplar based clustering with outlier selection based on the facility location formulation. Given a distance function and the number of outlie…
Network Traffic Decomposition for Anomaly Detection
Tahereh Babaie, Sanjay Chawla, Sebastien Ardon
In this paper we focus on the detection of network anomalies like Denial of Service (DoS) attacks and port scans in a unified manner. While there has been an extensive amount of re…
Sleep Analytics and Online Selective Anomaly Detection
Tahereh Babaie, Sanjay Chawla, Romesh Abeysuriya
We introduce a new problem, the Online Selective Anomaly Detection (OSAD), to model a specific scenario emerging from research in sleep science. Scientists have segmented sleep int…
Discovering the Network Backbone from Traffic Activity Data
Sanjay Chawla, Kiran Garimella, Aristides Gionis +1
We introduce a new computational problem, the BackboneDiscovery problem, which encapsulates both functional and structural aspects of network analysis. While the topology of a typi…
