Tradeoffs among Action Taking Policies Matter in Active Sequential Multi-Hypothesis Testing: the Optimal Error Exponent Region
Chia-Yu Hsu, I-Hsiang Wang
Reliability of sequential hypothesis testing can be greatly improved when the decision maker is given the freedom to adaptively take an action that determines the distribution of t…

On the Price of Decentralization in Decentralized Detection
Bruce, Huang, I-Hsiang Wang
Fundamental limits on the error probabilities of a family of decentralized detection algorithms (eg., the social learning rule proposed by Lalitha et al. over directed graphs are i…

A Unified Study on Sequentiality in Universal Classification with Empirically Observed Statistics
Ching-Fang Li, I-Hsiang Wang
In the binary hypothesis testing problem, it is well known that sequentiality in taking samples eradicates the trade-off between two error exponents, yet implementing the optimal t…
