利用条件概率和Gibbs抽样技术为分布估计算法构造通用概率模型张放;鲁华祥【期刊名称】《控制理论与应用》【年(卷),期】2013(030)003【摘要】A stochastic model based on conditional probability and Gibbs sampling is proposed to cope with the modeling problems occurred in traditional algorithms for distribution estimation, and extends the generality of the algorithm. The algorithm with this model takes promised individuals in the evolution process to form supervised training sets. For each of such sets, we estimate the conditional probability of a component given other components, and execute a Gibbs sampling procedure to generate new candidates for replacing inferior ones. The result of computer experiments shows that the improved algorithm can obtain the global optimum of additively decomposed functions, demonstrating a strong ability in global optimization.%本文针对传统分布估计算法在建立概率模型时面临的各种困难,提出一种基于条件概率和Gibbs抽样的概率模型,能有效改进分布估计算法的通用性.使用该模型的分布估计算法利用进化过程中有前途的优秀个体构造出多个监督学习样本集,并对每个样本集估计出对应分量的条件概率,再使用这一组条件概率进行Gibbs抽样产生新的个体替代种群中的劣等个体.通过仿真实验表明,改进后的算法能够求解出可加性降解函数的全局最优解,表现出较强的全局优化能力.【总页数】9页(P307-315)【作者】张放;鲁华祥【作者单位】中国科学院半导体研究所神经网络实验室,北京100083;中国科学院半导体研究所神经网络实验室,北京100083【正文语种】中文【中图分类】TP181【相关文献】1.一种多目标优化的多概率模型分布估计算法 [J], 钟润添;龚海峰;李斌;庄镇泉2.经验分布函数概率模型的分布估计算法 [J], 张建华;曾建潮3.基于条件概率模型的缺陷定位方法 [J], 舒挺;黄明献;丁佐华;王磊;夏劲松4.柯西分布概率模型的copula分布估计算法 [J], 赵慧;王丽芳;介婧5.基于概率模型的分布估计算法求解欺骗问题 [J], 丁才昌;殷晓东;卢露;余法红因版权原因,仅展示原文概要,查看原文内容请购买。

Phase diagramHello everybody, welcome to my class. Today, we will talk about phase diagram and Gibbs phase rule, as well as how to calculate the corresponding proportion of liquid phase and solid phase.译文:大家好,欢迎来到我的课程。
今天,我们将讨论相图,吉布斯相律,以及如何计算液相和固相的相对含量。
First of all, let’s introduce the definition of phase. Phase is defined as a homogeneous part or aggregation of material. This homogenous part is distinguished from another part due to difference in structure, composition, or both. The different structures form an interface to difference in structure and composition. (这里要注意相的概念,相是指在结构和组成方面与其它部分不同的均匀体。
)译文:我们首先学习相的定义。
相是指在一种材料中,结构、组成,或两者同时不同于其他部分的均匀体或聚集体部分。
不同部分间形成界面,也就是相与相之间的分界面。
Some solid materials have the capability of changing their crystal structure under the varying conditions of pressure and temperature, causing an ability of phase-change.译文:一些固体材料随着压力和温度条件的改变而发生结晶结构变化,具有相变的能力。
