Over the last six decades, the representation of error exponent functions for data transmission through noisy channels at rates below capacity has seen three distinct approaches: (1) Through Gallager's functions (with and without cost constraints); (2) large deviations form, in terms of conditional relative entropy and mutual information; (3) through the -mutual information and the Augustin-Csiszár mutual information of order derived from the Rényi divergence[...].
在过去的六十年里，对于通过有噪声信道以低于容量的速率进行数据传输的误差指数函数表示，出现了三种不同的方法：（1）通过加拉格尔函数（有和没有成本约束）；（2）根据条件相对熵和互信息的大偏差形式；（3）通过从雷尼散度导出的 - 互信息和阶数为 的奥古斯丁 - 西斯扎尔互信息[……]。
