The Gaussian Mixture distribution is a linear superposition of Gaussians
각 데이터 포인트가 특정한 가우시안 분포에서 생성된다고 가정하고 z variables are
Latent Variable
Multinomial Distribution
we introduce K-dimensional binary random variable z in which only one element zk is equal to 1 and the others are all 0.
Therefore we can induce first equation easily using
Marginalization
