基于$f$ -分歧估计过程中贝叶斯风险的下界

Lower-bounds on the Bayesian Risk in Estimation Procedures via $f$-Divergences

Adrien Vandenbroucque, Amedeo Roberto Esposito, Michael Gastpar

摘要:

我们认为在贝叶斯设置的参数估计的问题,并提出了一个一般的下限,包括家庭的$f$分歧的一部分。然后将结果应用于感兴趣的特定设置,并与文献中的其他显著结果进行比较。特别是,我们表明,使用互信息的已知界限可以通过使用,例如,最大泄漏,海林格发散,或广义的曲棍球棒发散。

英文摘要:

We consider the problem of parameter estimation in a Bayesian setting and propose a general lower-bound that includes part of the family of $f$-Divergences. The results are then applied to specific settings of interest and compared to other notable results in the literature. In particular, we show that the known bounds using Mutual Information can be improved by using, for example, Maximal Leakage, Hellinger divergence, or generalizations of the Hockey-Stick divergence.
