Low-rank Matrix Bandits with Heavy-tailed Rewards
Yue Kang, Cho-Jui Hsieh, Thomas C. M. Lee
In stochastic low-rank matrix bandit, the expected reward of an arm is equal to the inner product between its feature matrix and some unknown by low-rank parameter matr…

Efficient Frameworks for Generalized Low-Rank Matrix Bandit Problems
Yue Kang, Cho-Jui Hsieh, Thomas C. M. Lee
In the stochastic contextual low-rank matrix bandit problem, the expected reward of an action is given by the inner product between the action's feature matrix and some fixed, but…
