模式识别第一次作业
- 1. 用 dataset1.txt 作为训练样本,用dataset2.txt 作为测试样本,采用身高和体重数据为特征,在正态分布假设下估计概率密度(只用训练样本),建立最小错误率贝叶斯分类器,写出所用的密度估计方法和得到的决策规则,将该分类器分别应用到训练集和测试集,考察训练错误率和测试错误率。将分类器应用到dataset3 上,考察测试错误率的情况。(1. using dataset1.txt as training samples as test samples by dataset2.tx
singlephasefullbridgeinverter
- 单相全桥逆变器模型,测试OK,直接运行,需要的参考(Single phase full bridge inverter model)
EM算法
- 在统计计算中,最大期望(EM)算法是在概率(probabilistic)模型中寻找参数最大似然估计或者最大后验估计的算法,其中概率模型依赖于无法观测的隐藏变量(Latent Variable)。最大期望经常用在机器学习和计算机视觉的数据聚类(Data Clustering)领域。(In statistical calculation, the expectation maximization (EM) algorithm in probability (probabilistic) maximu

第六章 聚类分析
- 聚类分析指将物理或抽象对象的集合分组为由类似的对象组成的多个类的分析过程。它是一种重要的人类行为。聚类分析的目标就是在相似的基础上收集数据来分类(Clustering analysis refers to the grouping of physical or abstract objects into groups that are composed of similar objects. It is an important human behavior. The goal of clust
