------------------------------------------
Summary: Change default maxPatternLength value to Int.MaxValue in
PrefixSpan
Key: SPARK-20203
URL: https://issues.apache.org/jira/browse/SPARK-20203
Project: Spark
Issue Type: Wish
Components: MLlib
Affects Versions: 2.1.0
Reporter: Cyril de Vogelaere
Priority: Trivial
I think changing the default value to Int.MaxValue would
be more user friendly. At least for new user.
Personally, when I run an algorithm, I expect it to find all solution by
default. And a limited number of them, when I set the parameters so.
The current implementation limit the length of solution patterns to 10.
Thus preventing all solution to be printed when running slightly large datasets.
