| 释义 | decision content 判定量;［决定量］ In information theory, a logarithmic measure of the number of decisions needed to select a given event among a finite number of mutually exclusive events; in mathematical notation, this measure is:H0=logn. Where n is the number of events. The base of the logarithm determines the unit used. The decision content is independent of the probabilities of the occurrence of the events. However, in some applications, it is assumed that these probabilities are equal. 在信息论中,从有限的互斥事件中选择一给定事件时所需判定次数的对数量度。用数学表 示法表示,这个量度为:H0=log n。这里n是事件的数目。对数的底决定了所用的单位。决 策量与各事件出现的概率无关,但在某些应用中,假设这些概率是相等的。 |
