Infinite Mixture-of-experts model. Left panel: Mixture-of-experts model for two experts with a gating node representing the function that decides which of the two experts is chosen to make a prediction for x which is represented by p(c
j
|x, ●) in eq. (13). Right panel: Infinite mixture of experts using a Dirichlet process prior G with parameters (α, G0). N denotes the number of observations and c
i
the respective assignment variables. The observed variables x and t are represented in green with the priors collapsed to 
. In the full model, the part will be replaced by Figure 1.
