Subject Default value of numGroups in FPGrowthJob
Date Tue, 06 Sep 2011 09:13:09 GMT
Hi,

I tried FPGrowthJob using mahout command below.
1. $MAHOUT_HOME/bin/mahout fpg -i /input/retail.dat -o /output/numgdef/
-method mapreduce -regex '[\s]' -s 100
2. $MAHOUT_HOME/bin/mahout fpg -i /input/retail.dat -o /output/numg50/
-method mapreduce -regex '[\s]' -s 100 --numGroups 50
3. $MAHOUT_HOME/bin/mahout fpg -i /input/retail.dat -o /output/numg1000/
-method mapreduce -regex '[\s]' -s 100 --numGroups 1000

1. and 2. were same results. but 3.(--numGroups 1000) was different.

The document page shows numGroups default 1000.

I think default value is 50. Is my thinking right?
