Frank McQuillan updated MADLIB-1060:
------------------------------------
Description:
Follow on to
https://issues.apache.org/jira/browse/MADLIB-927
{code}
knn( point_source,
point_column_name,
label_column_name,
test_source,
test_column_name,
id_column_name,
output_table,
operation,
k
)
{code}
Possible improvements:
1) The parameters 'point_column_name' and 'test_column_name' should support
regular PostgreSQL expressions.
2) Should we infer 'c' or 'r' from the data types, rather than have to say
explicitly?
