`h2o.distance.Rd`

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

h2o.distance(x, y, measure)

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) |

# NOT RUN { 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") # }
