Classification algorithm for self - learning naive bayes based on conditional information entropy 基于条件信息熵的自主式朴素贝叶斯分类算法
2 ) by analyzing the information and conditional information description mechanism of system states , the problem of stochastic model reduction is investigated based on state aggregation . the information loss and conditional information loss between the full - and reduced - order models are measured by entropy , while the independence and conditional independence within me components of aggregated state are measured by kullback - leibler information distance . several model reduction methods for stable and unstable linear systems are derived by employing two criteria to get aggregation matrices : the minimal information loss and the maximal independence 2 )分析了随机系统状态空间模型中的信息和条件信息描述机制,以shannon熵为手段描述线性系统模型降阶过程中的信息和条件信息损失,以kullback - leibler信息作为衡量降阶模型状态向量各分量之间统计独立性的测度,针对稳定和不稳定系统研究基于状态集聚的模型降阶问题:分别运用最小信息损失准则和最大独立性原则,得出几种状态集聚的信息论方法,并讨论降阶模型的性质、阶次的确定、系统噪声分布特性等问题。
