  1. (, Uncertainty in artificial intelligence)
    We investigate the problem of combinatorial multi-armed bandits with stochastic submodular (in expectation) rewards and full-bandit feedback, where no extra information other than the reward of selected action at each time step is observed. We propose a simple algorithm, Explore-Then-Commit Greedy (ETCG) and prove that it achieves a -regret upper bound of for a horizon , number of base elements , and cardinality constraint . We also show in experiments with synthetic and real-world data that the ETCG empirically outperforms other full-bandit methods.
