Random Values:

Concept Meaning
Discrete Random Variables
Probability mass function / pmf P()
判别分类器 Discriminative Classifier P(Y=c|x)
生成分类器 Generative Classifier P(Y=c|x)=P(Y=c|θ)P(x|Y=c,θ)∑c′P(Y=c′|θ)P(x|Y=c′,θ)
Unconditionally / marginally independent P(x,y)=P(x)P(y)
Conditionally independent P(x,y|z)=P(x|z)P(y|z)
P(x,y|z)=g(x,z)h(y,z),∀x,y,z such that P(z)>0
Continuous Random Variables
Cumulative distribution function / cdf F(x)=P(X≤x)
Probability density function / pdf f(x)=dF(x)dx
α Quantile of F F−1(α)=xα such that P(X≤xα)=α
Median
