updateU function

Update time-constant latent node positions

updateU(K, U, V, R, Zb, s2, eU, iVU)

Arguments

• K: The dimensionality of Z
• U: The most recent draw of latent node positions
• V: Layer-specific network generation rule
• R: The dimensionality of latent space
• Zb: Z - beta
• s2: error variance
• eU: The mean of U
• iVU: The variance of U

Returns

A matrix of time-constant latent node positions
