Piecewise-Stationary Combinatorial Semi-Bandit with Causally Related Rewards
Behzad Nourani-Koliji, Steven Bilaj, Amir Rezaei Balef +1
We study the piecewise stationary combinatorial semi-bandit problem with causally related rewards. In our nonstationary environment, variations in the base arms' distributions, cau…

Linear Combinatorial Semi-Bandit with Causally Related Rewards
Behzad Nourani-Koliji, Saeed Ghoorchian, Setareh Maghsudi
In a sequential decision-making problem, having a structural dependency amongst the reward distributions associated with the arms makes it challenging to identify a subset of alter…
