Build Similarity Matrix From Forest Weights

Build Similarity Matrix From Forest Weights

Usage

build_similarity_from_weights(
  W,
  similarity_type = c("second", "first"),
  zero_diag = TRUE,
  symm = TRUE
)

Arguments

W

A square forest-weight matrix.

similarity_type

Similarity structure: "second" uses W %*% t(W); "first" uses (W + t(W))/2.

zero_diag

Logical; whether to zero out diagonal entries in similarity.

symm

Logical; whether to force symmetry by averaging with transpose.

Value

A sample-by-sample similarity matrix.
