Gaussian Distribution
The density can be estimated by multiples of Gaussian Kernels
The mixing coefficients are themselves probabilities and must meet this condition: sum(pi)=1
Lets use the Maximum Likelihood Estimation to find the optimal parameter. This can be solved by E-M algorithm/
머신러닝/패턴인식, 오일석
is prior, not likelihood.
How to find the optimal parameter ?
