Regenerative Particle Thompson Sampling
Zeyu Zhou, Bruce Hajek, Nakjung Choi +1
This paper proposes regenerative particle Thompson sampling (RPTS), a flexible variation of Thompson sampling. Thompson sampling itself is a Bayesian heuristic for solving stochast…
Blockchain Security when Messages are Lost
Taha Ameen, Suryanarayana Sankagiri, Bruce Hajek
Security analyses for consensus protocols in blockchain research have primarily focused on the synchronous model, where point-to-point communication delays are upper bounded by a k…
Maximum Likelihood Estimation of Optimal Receiver Operating Characteristic Curves from Likelihood Ratio Observations
Bruce Hajek, Xiaohan Kang
The optimal receiver operating characteristic (ROC) curve, giving the maximum probability of detection as a function of the probability of false alarm, is a key information-theoret…
The Longest-Chain Protocol Under Random Delays
Suryanarayana Sankagiri, Shreyas Gandlur, Bruce Hajek
In the field of distributed consensus and blockchains, the synchronous communication model assumes that all messages between honest parties are delayed at most by a known constant…
Lower Bounds on Information Requirements for Causal Network Inference
Xiaohan Kang, Bruce Hajek
Recovery of the causal structure of dynamic networks from noisy measurements has long been a problem of interest across many areas of science and engineering. Many algorithms have…
On non-unique solutions in mean field games
Bruce Hajek, Michael Livesay
The theory of mean field games is a tool to understand noncooperative dynamic stochastic games with a large number of players. Much of the theory has evolved under conditions ensur…
