Blahut 和 Arimoto 主题的变体（英文版）

英文标题：Variations on a Theme by Blahut and Arimoto中文摘要：通过使用一维根查找步骤和牛顿法更新固定乘数的 Blahut-Arimoto 算法的新修改版，可以使算法更加灵活和高效，直接计算给定目标失真下的速率失真函数，并且收敛速度为 O（1/n）。英文摘要：The Blahut-Arimoto (BA) algorithm has played a fundamental role in thenumerical computation of rate-distortion (RD) functions. This algorithmpossesses a desirable monotonic convergence property by alternativelyminimizing its Lagrangian with a fixed multiplier. In this paper, we propose anovel modification of the BA algorithm, letting the multiplie
