Initialize GMM parameters using an ordering method

initialize_ordering(
  X,
  K,
  method = c("PCA", "fiedler", "pcurve", "tSNE", "random", "isomap"),
  discretization = c("equal", "quantile", "kmeans"),
  ...
)

Arguments

X: numeric matrix (n x d).
K: number of mixture components.
method: ordering method.
discretization: discretization method passed to make_init().
...: forwarded to the ordering method function.

Value

list(pi, mu, sigma, keep_idx, cluster_rank, ordering)
