Optimal Tracking in Prediction with Expert Advice
Hakan Gokcesu, Suleyman S. Kozat
We study the prediction with expert advice setting, where the aim is to produce a decision by combining the decisions generated by a set of experts, e.g., independently running alg…
Recursive Experts: An Efficient Optimal Mixture of Learning Systems in Dynamic Environments
Kaan Gokcesu, Hakan Gokcesu
Sequential learning systems are used in a wide variety of problems from decision making to optimization, where they provide a 'belief' (opinion) to nature, and then update this bel…
Minimax Optimal Online Stochastic Learning for Sequences of Convex Functions under Sub-Gradient Observation Failures
Hakan Gokcesu, Suleyman S. Kozat
We study online convex optimization under stochastic sub-gradient observation faults, where we introduce adaptive algorithms with minimax optimal regret guarantees. We specifically…
An Asymptotically Optimal Algorithm for Communicating Multiplayer Multi-Armed Bandit Problems
Noyan Evirgen, Alper Kose, Hakan Gokcesu
We consider a decentralized stochastic multi-armed bandit problem with multiple players. Each player aims to maximize his/her own reward by pulling an arm. The arms give rewards ba…
