Streaming Algorithms for News and Scientific Literature Recommendation: Submodular Maximization with a d-Knapsack Constraint
Qilian Yu, Easton Li Xu, Shuguang Cui
Submodular maximization problems belong to the family of combinatorial optimization problems and enjoy wide applications. In this paper, we focus on the problem of maximizing a mon…
Detection of Cooperative Interactions in Logistic Regression Models
Easton Li Xu, Xiaoning Qian, Tie Liu +1
An important problem in the field of bioinformatics is to identify interactive effects among profiled variables for outcome prediction. In this paper, a logistic regression model w…
The Minimum Number of Hubs in Networks
Easton Li Xu, Guangyue Han
In this paper, a hub refers to a non-terminal vertex of degree at least three. We study the minimum number of hubs needed in a network to guarantee certain flow demand constraints…
A Graph Theoretical Approach to Network Encoding Complexity
Li Xu, Weiping Shang, Guangyue Han
Consider an acyclic directed network with sources and distinct sinks . For , let denote the min-cut between an…
