演題 | Shape constraint approaches for Gaussian noise model estimation (文献紹介) |
概要 |
Estimation of mixture densities for the classical Gaussian compound decision problem and their associated nonparametric (empirical) Bayes rules is considered from two new perspectives. One is motivated by Brown and Greenshtein [1] and another is motivated by Jiang and Zhang [2]. In the paper that will be introduced [3], the authors apply shape constraint method to both approaches and the estimation problems are transformed to convex optimization problems that can be efficiently solved by modern interior point methods. (And it is possible that some other shape constraint topics will also be introduced briefly.) 参考文献 |
