Xiangrui Meng commented on SPARK-7352:
--------------------------------------
+1 on keeping `minDocFreq`, which is well-defined, e.g., in the IR book:
http://nlp.stanford.edu/IR-book/html/htmledition/inverse-document-frequency-1.html
> ml.feature.IDF should rename minDocFreq to minDocCount
> ------------------------------------------------------
