h2o.distance function

Compute a pairwise distance measure between all rows of two numeric H2OFrames.

Compute a pairwise distance measure between all rows of two numeric H2OFrames.

h2o.distance(x, y, measure)

Arguments

  • x: An H2OFrame object (large, references).
  • y: An H2OFrame object (small, queries).
  • measure: An optional string indicating what distance measure to use. Must be one of: "l1" - Absolute distance (L1-norm, >=0) "l2" - Euclidean distance (L2-norm, >=0) "cosine" - Cosine similarity (-1...1) "cosine_sq" - Squared Cosine similarity (0...1)

Examples

## Not run: library(h2o) h2o.init() prostate_path <- system.file("extdata", "prostate.csv", package = "h2o") prostate <- h2o.uploadFile(path = prostate_path) h2o.distance(prostate[11:30, ], prostate[1:10, ], "cosine") ## End(Not run)
