Researchers have developed new frameworks for the combinatorial semi-bandit problem, which involves selecting subsets of base arms and receiving individual feedback. These frameworks significantly reduce the number of required oracle queries, a major bottleneck for scalability. The proposed algorithms achieve near-optimal regret bounds with only logarithmic oracle calls, even extending to non-linear reward settings. AI
