Dirichlet Process 和 Dirichlet Process Mixture模型 [本文链接:http://www.cnblogs.com/breezedeus/archive/2012/11/05/2754940.html,转载请注明出处.] Dirichlet Process (DP)被称为分布的分布.从DP抽取出的每个样本(一个函数)都可以被认为是一个离散随机变量的分布函数,这个随机变量以非零概率值在可数无穷个离散点上取值.比较有意思的是,从DP可以推导出几个非常著名的问题:…
Dialogue 1 Healthy diet 关于健康饮食 F:Bob, look at this sentence. 'Healthy eating is not about strict nutrition philosophies, staying unrealistically thin, or depriving yourself of foods you love.' It's interesting, isn't it? 鲍勃,听听这个句子:健康的饮食不是指那些严格的营养哲…
先明确一些潜规则: 机器学习是个collection or set of models,一切实践性强的模型都会被归纳到这个领域,没有严格的定义,’有用‘可能就是唯一的共性. 机器学习大概分为三个领域: 一般的机器学习模型:没有掺杂太多统计概念,例如决策树,KNN聚类,感知机等. 统计机器学习模型:依赖统计理论,主要是贝叶斯统计,例如SVM,naive bayesian,贝叶斯线性回归,高斯过程等. 神经网络模型:可以简单的理解为感知机的扩展,因为扩展的太猛,单独成立门派咯. 如此定义,有助于菜鸡…
