摘要:

我们重新回顾了Qin等人(2014)对C $^2$ UCB上下文组合强盗的有界遗憾的证明。我们证明了一个错误的体积膨胀的矩矩阵的证明,用于上界的上下文向量范数的函数。我们证明了一个宽松的不平等,产生原来规定的遗憾界。

英文摘要:

We revisit the proof by Qin et al. (2014) of bounded regret of the C$^2$UCB contextual combinatorial bandit. We demonstrate an error in the proof of volumetric expansion of the moment matrix, used in upper bounding a function of context vector norms. We prove a relaxed inequality that yields the originally-stated regret bound.
