elbo_monitoring_VEM(hp_k, hp_i, db, kern_i, kern_k, hyperpost, m_k, pen_diag)
hp_k |
A tibble, data frame or named vector of hyper-parameters for each clusters. |
hp_i |
A tibble, data frame or named vector of hyper-parameters for each individuals. |
db |
A tibble containing values we want to compute elbo on. Required columns: Input, Output. Additional covariate columns are allowed. |
kern_i |
Kernel used to compute the covariance matrix of individuals GPs at corresponding inputs. |
kern_k |
Kernel used to compute the covariance matrix of the mean GPs at corresponding inputs. |
hyperpost |
A list of parameters for the variational distributions of the K mean GPs. |
m_k |
Prior value of the mean parameter of the mean GPs (mu_k). Length = 1 or nrow(db). |
pen_diag |
A jitter term that is added to the covariance matrix to avoid numerical issues when inverting, in cases of nearly singular matrices. |
Value of the elbo that is maximised during the VEM algorithm used for training in MagmaClust.
