一个信源输出的符号前后有相关性时，信号输出的熵将减少，这就是一种形式的剩余。 信源的剩余度，也称为多余度，与熵的减少有关。因此，香农用熵的降低量来定义剩余度。剩余度是信源信息率的多余程度，也称冗余度或冗长度。通常用一个相对值表示。信源的剩余度越大，信源的数据压缩潜力就越大，信源信息处理也就越必要。工程上采用的信源编码、数据压缩、频带压缩均基于这一事实。

熵是复杂度的度量标准，而如果您现在由于某个问题的及时解决方案增加了复杂度，则必须在项目的剩余生命周期内为此付出一些代价。
Entropy is a measure of complexity, and if you add complexity now because of a just-in-time solution to a problem, you must pay some price for that for the remaining life of the project.
