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) |
