Partial-monotone adaptive submodular maximization
Shaojie Tang et al.
Summary: Many AI/Machine learning problems involve adaptively selecting a sequence of items with the goal of maximizing an adaptive submodular function. Existing studies mainly focus on monotone or non-monotone cases. This research generalizes previous results and shows that even for a non-monotone utility function, a random greedy policy can achieve an approximation ratio close to (1 - 1/e) if the function is close to a monotone function.
