Abstract

En 中文
Two-stage submodular maximization problem under cardinality constraint has been widely studied in machine learning and combinatorial optimization. In this paper, we consider knapsack constraint. In this problem, we give n articles and m categories, and the goal is to select a subset of articles that can maximize the function F(S). Function F(S) consists of m monotone submodular functions f(j), j=1,2, ..., m, and each f(j) measures the similarity of each article in category j. We present a constant-approximation algorithm for this problem.
