Online Learning Algorithms for Stochastic Water-Filling
Yi Gai, Bhaskar Krishnamachari
Water-filling is the term for the classic solution to the problem of allocating constrained power to a set of parallel channels to maximize the total data-rate. It is used widely i…
Online Learning for Combinatorial Network Optimization with Restless Markovian Rewards
Yi Gai, Bhaskar Krishnamachari, Mingyan Liu
Combinatorial network optimization algorithms that compute optimal structures taking into account edge weights form the foundation for many network protocols. Examples include shor…
Efficient Online Learning for Opportunistic Spectrum Access
Wenhan Dai, Yi Gai, Bhaskar Krishnamachari
The problem of opportunistic spectrum access in cognitive radio networks has been recently formulated as a non-Bayesian restless multi-armed bandit problem. In this problem, there…
Decentralized Online Learning Algorithms for Opportunistic Spectrum Access
Yi Gai, Bhaskar Krishnamachari
The fundamental problem of multiple secondary users contending for opportunistic spectrum access over multiple channels in cognitive radio networks has been formulated recently as…
