指数强逆的有损恢复内容识别

Exponential Strong Converse for Content Identification with Lossy Recovery

Lin Zhou, Vincent Y. F. Tan, Lei Yu, Mehul Motani

摘要:

我们重新审视了高维内容识别与有损恢复问题(Tuncel和Gündüz,2014),并建立了一个指数强逆定理。作为指数强逆定理的推论,我们得到了该问题的联合识别误差和过度失真指数的上界。我们的主要结果可以专门用于生物识别问题~(Willems,2003)和内容识别问题~(Tuncel,2009),因为这两个问题都是内容识别与有损恢复问题的特殊情况。我们利用Oohama引入的信息谱方法,并采用其中的强逆技术来解决手头的问题。

英文摘要:

We revisit the high-dimensional content identification with lossy recovery problem (Tuncel and Gündüz, 2014) and establish an exponential strong converse theorem. As a corollary of the exponential strong converse theorem, we derive an upper bound on the joint identification-error and excess-distortion exponent for the problem. Our main results can be specialized to the biometrical identification problem~(Willems, 2003) and the content identification problem~(Tuncel, 2009) since these two problems are both special cases of the content identification with lossy recovery problem. We leverage the information spectrum method introduced by Oohama and adapt the strong converse techniques therein to be applicable to the problem at hand.
