Compute element-wise string distances between two H2OFrames
Compute element-wise string distances between two H2OFrames. Both frames need to have the same shape (N x M) and only contain string/factor columns. Return a matrix (H2OFrame) of shape N x M.
h2o.stringdist(
x,
y,
method = c("lv", "lcs", "qgram", "jaccard", "jw", "soundex"),
compare_empty = TRUE
)x |
An H2OFrame |
y |
A comparison H2OFrame |
method |
A string identifier indicating what string distance measure to use. Must be one of: "lv" - Levenshtein distance "lcs" - Longest common substring distance "qgram" - q-gram distance "jaccard" - Jaccard distance between q-gram profiles "jw" - Jaro, or Jaro-Winker distance "soundex" - Distance based on soundex encoding |
compare_empty |
if set to FALSE, empty strings will be handled as NaNs |
