gapp for model inference what is the model of likelihood in ep what is the use of expectation propagation what is an example of expectation propagation in a joint probability distribution? what type of distribution is $p(y)$ what is model noise pp what is the probability distribution of $p what is the probability term for phi in the model which condition can be used to model inference? ep vs expectation propagation what is the model noise distribution? which model uses expectation propagation? what is gamma model what is expectation propagation which term of model is modelled by the gamma distribution? what is the use of expectation propagation in a gamma distribution what is the use of expectation propagation? what is the use of expectation propagation what is the use of expectation propagation is phi a normal distribution
