Fit a reference-area model from embeddings parquet — fit_ridge • openalexVectorComp

Fits a reference-area model (centroid + regularized covariance inverse) using rows from reference_label.

Usage

fit_ridge(
  embeddings,
  reference_label = "reference",
  output,
  regularization = 1e-06,
  verbose = TRUE
)

Arguments

embeddings: Path to a Parquet dataset (file or directory opened by Arrow) with columns id, label, and V1..Vd.
reference_label: Label partition used to define the reference area.
output: Name of the .rds file to save the fit object.
regularization: Positive numeric diagonal regularization added to covariance.
verbose: Logical; print progress messages.

Value

Invisibly returns output.
