Asymptotics for Outlier Hypothesis Testing
Lin Zhou, Yun Wei, Alfred Hero
We revisit the outlier hypothesis testing framework of Li \emph{et al.} (TIT 2014) and derive fundamental limits for the optimal test. In outlier hypothesis testing, one is given m…

Convergence of de Finetti's mixing measure in latent structure models for observed exchangeable sequences
Yun Wei, XuanLong Nguyen
Mixtures of product distributions are a powerful device for learning about heterogeneity within data populations. In this class of latent structure models, de Finetti's mixing meas…
