Asynchronous Stochastic Optimization Robust to Arbitrary Delays
Alon Cohen, Amit Daniely, Yoel Drori +2
We consider stochastic optimization with delayed gradients where, at each time step , the algorithm makes an update using a stale stochastic gradient from step for som…

Minimax Regret for Stochastic Shortest Path
Alon Cohen, Yonathan Efroni, Yishay Mansour +1
We study the Stochastic Shortest Path (SSP) problem in which an agent has to reach a goal state in minimum total expected cost. In the learning formulation of the problem, the agen…

Online Markov Decision Processes with Aggregate Bandit Feedback
Alon Cohen, Haim Kaplan, Tomer Koren +1
We study a novel variant of online finite-horizon Markov Decision Processes with adversarially changing loss functions and initially unknown dynamics. In each episode, the learner…
