Greedy approximations for minimum submodular cover with submodular cost
It is well-known that a greedy approximation with an integer-valued polymatroid potential function f is H(γ )-approximation of the minimum submodular cover problem with linear cost where γ is the maximum value of f over all singletons and H(γ ) is the γ -th harmonic number. In this paper, we establish similar results for the minimum submodular cover problem with a submodular cost (possibly nonl...
متن کاملSubmodular Optimization with Submodular Cover and Submodular Knapsack Constraints
We investigate two new optimization problems — minimizing a submodular function subject to a submodular lower bound constraint (submodular cover) and maximizing a submodular function subject to a submodular upper bound constraint (submodular knapsack). We are motivated by a number of real-world applications in machine learning including sensor placement and data subset selection, which require ...
متن کاملThe Minimum Entropy Submodular Set Cover Problem
We study minimum entropy submodular set cover, a variant of the submodular set cover problem (Wolsey [22], Fujito [11], etc) that generalizes the minimum entropy set cover problem (Halperin and Karp [12], Cardinal et al. [5]) We give a general bound of the approximation performance of the greedy algorithm using an approach that can be interpreted in terms of a particular type of biased network ...
متن کاملInteractive Submodular Set Cover
We introduce a natural generalization of submodular set cover and exact active learning with a finite hypothesis class (query learning). We call this new problem interactive submodular set cover. Applications include advertising in social networks with hidden information. We give an approximation guarantee for a novel greedy algorithm and give a hardness of approximation result which matches up...
متن کاملScenario Submodular Cover
Many problems in Machine Learning can be modeled as submodular optimization problems. Recent work has focused on stochastic or adaptive versions of these problems. We consider the Scenario Submodular Cover problem, which is a counterpart to the Stochastic Submodular Cover problem studied by Golovin and Krause (2011). In Scenario Submodular Cover, the goal is to produce a cover with minimum expe...
