entropy of information meaning in English
信息熵
Examples
- The algorithm makes use of maximum entropy of information theory and gets optimal solution by a small - scale
该算法利用了信息论中极大熵原理，使算法以较小的规模得到较好的最优解。 - And weighted infromation entropy and weighted conditional entropy of information system based on set - value function is presented also
还提出了基于一般的集值函数的信息系统加权信息熵和条件熵概念。 - So far , there have been many heuristic algorithms for building decision trees . most are based on the entropy of information or vagueness , such as id3 , min - ambiguity and their variation
目前，已有许多种构建决策树的方法，大多数是基于信息熵的或信息的不确定性，例如， id3算法， min ? ambiguity算法以及它们的变异版本。 - 3 adopting the theory of entropy of information to set up the definition and formula of the market transaction entropy , the market structure entropy and the market competition degree , provide the theory and method to analyses the changing tendency of coal industry market competition
3 、依据信息熵的理论，创建了市场交易熵、市场结构熵和市场竞争度的概念和计算公式，并建立了市场交易和市场结构的熵函数，为分析煤炭产业市场竞争的变化趋势提供了理论方法。 - Based on the information theory , it is proved that the entropy of information system and the mutual information of decision system are constant in the hierarchization of attributes . so the rst hierarchical reduction approaches have strict mathematic basis . the application in acquiring the control decision of a cement kiln shows the validity of the hierarchical reduction approach
本文从信息理论的角度分别证明属性分层递阶不改变信息系统的信息熵和决策系统的互信息，从而使分层递阶约简算法体系具有严格的数学基础；分层递阶约简算法在某水泥窑炉控制决策获取中的应用证实其有效性。
