摘要
本文探讨了信息论中平均互信息和广义相关系数的关系。证明了平均互信息的可加性,在此基础上得到了广义相关系数不等式,并给出了等式成立的充要条件。研究表明平均互信息的增加不意味着广义相关系数也增加。
In this paper, we study the relationship between average mutual communication and general correlation coefficient in information theory. Additivity of average mutual communication is proved, based on this, inequality for general correlation coefficients is derived, and the necessary and sufficient condition is obtained for equality. It shows that the increase in average mutual communication does not mean the increase in general correlation coefficient.
