Non-stationary Delayed Combinatorial Semi-Bandit with Causally Related Rewards

no code implementations18 Jul 2023 Saeed Ghoorchian, Setareh Maghsudi

We develop a policy that learns the structural dependencies from delayed feedback and utilizes that to optimize the decision-making while adapting to drifts.

Linear Combinatorial Semi-Bandit with Causally Related Rewards

no code implementations25 Dec 2022 Behzad Nourani-Koliji, Saeed Ghoorchian, Setareh Maghsudi

The objective is to maximize the long-term average payoff, which is a linear function of the base arms' rewards and depends strongly on the network topology.

Multi-Armed Bandit for Energy-Efficient and Delay-Sensitive Edge Computing in Dynamic Networks with Uncertainty

no code implementations12 Apr 2019 Saeed Ghoorchian, Setareh Maghsudi

The full potential of edge computing becomes realized only if a smart device selects the most appropriate server in terms of the latency and energy consumption, among many available ones.
