生成模型(Generative)和判别模型(Discriminative) 引言 最近看文章<A survey of appearance models in visual object tracking>(XiLi,ACMTIST,2013),在文章的第4节第1段有这样的描述,“Recently,visualobject tracking has been posed as a tracking-by-detectionproblem, where statistical modeli
Andrew Ng, On Discriminative vs. Generative classifiers: A comparison of logistic regression and naive Bayes 无论是生成式模型还是判别式模型,都可作为分类器使用,分类器的数学表达即为:给定输入 X 以及分类变量 Y,求 P(Y|X). 判别式模型直接估算 P(Y|X),或者也可像 SVM 那样,估算出输入和输出之间的映射,与概率无关: 判别式模型的典型代表是:logistic 回归: 产生
