Joseph K. Bradley resolved SPARK-19899. --------------------------------------- Resolution: Fixed Fix Version/s: 2.2.0 Issue resolved by pull request 17321 [https://github.com/apache/spark/pull/17321] > FPGrowth input column naming > ---------------------------- > > Key: SPARK-19899 > URL: https://issues.apache.org/jira/browse/SPARK-19899 > Project: Spark > Issue Type: Improvement > Components: ML > Affects Versions: 2.2.0 > Reporter: Maciej Szymkiewicz > Assignee: Maciej Szymkiewicz > Fix For: 2.2.0 > > > Current implementation extends {{HasFeaturesCol}}. Personally I find it > rather unfortunate. Up to this moment we used consistent conventions - if we > mix-in {{HasFeaturesCol}} the {{featuresCol}} should be {{VectorUDT}}. > Using the same {{Param}} for an {{array<T>}} (and possibly for > {{array<arrray<T>>}} once {{PrefixSpan}} is ported to {{ml}}) will be > confusing for the users. > I would like to suggest adding new {{trait}} (let's say > {{HasTransactionsCol}}) to clearly indicate that the input type differs for > the other {{Estiamtors}}. -- This message was sent by Atlassian JIRA (v6.3.15#6346) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
