由于马尔可夫信号年龄最小化一般意味着预测误差最小化，我们追求在本文中的年龄和我们所谓的有效年龄之间的潜在联系。有效年龄被松散地定义为与年龄相关的度量，其捕获信号的信息结构和所使用的采样模式，并且当误差最小化时，有效年龄被最小化。我们考虑几种选择采样mechanisms和信号模型，我们评估年龄和预测/估计误差的步骤，在寻求一个有意义的有效年龄概念定义。
Since for Markov signals age minimization generally implies prediction error minimization, we pursue in this paper the potential connection between age and what we call effective age. Effective age is loosely defined as an age-related metric that captures both the information structure of the signal and the sampling pattern that is used, and that it is minimized when the error is minimized. We consider several options for sampling mecha nisms and signal models, and we evaluate age and prediction/estimation errors as steps in the quest for a meaningful effective age concept definition.
