## Understanding Empirical Data Distribution"We can approximate $p\left(x,y\right)=p\left(x\right)p\left(y|x\right)$ using the empirical data distribution$p\left(x,y\right)=\frac{1}{N}\sum _{n=1}^{N}{\delta }_{{x}_{n}}\left(x\right){\delta }_{{y}_{n}}\left(y\right)"$In another part of the paper they say $p\left(y|{y}_{n}\right)={\delta }_{{y}_{n}}\left(y\right)$.I have some background in probability but none in statistics; I was able to figure out what an Empirical CDF is, but not a pdf like here, so I'm not sure exactly what the authors are doing.
