R Documentation

Calculate cosine similarity.

Description

Calculate cosine similarity of two vectors. Note: Much faster for pairwise comparisons than proxy::simil.

Usage

cosine_similarity(x, ...)

## S4 method for signature 'numeric'
cosine_similarity(x, y)

## S4 method for signature 'TermDocumentMatrix'
cosine_similarity(x, y = NULL, progress = TRUE, verbose = TRUE, mc = FALSE)

## S4 method for signature 'matrix'
cosine_similarity(
  x,
  how = c("proxy", "coop", "algebra"),
  chunks = 1,
  progress = TRUE,
  verbose = TRUE,
  mc = FALSE
)

## S4 method for signature 'big.matrix'
cosine_similarity(x)

Arguments

`x`	A matrix.
`...`	further parameters (for use with blapply)
`y`	simple triplet matrix
`progress`	logical
`verbose`	logical
`mc`	logical, or if numeric, providing number of cores
`how`	The tool/package chosen.
`chunks`	Number of chunks (numeric/integer value).
