I am actually modeling charges. The main use case is when we have charges a,b
and c then we have charge d with a confidence, support, lift, etc...Then when I
get an account with some charges, I look this up against the model to see if
any charge may be missing (based on confidence)+

Jeff, are you trying to build a general recommender? Or a shopping cart

recommendations based on some partial group of items (watchlist, wishlist,
shopping cart). FPG has been deprecated in favor of newer methods.

Hi Jeff, as I recall the map-reduce-based fp-growth solution was
problematic, and it's been either deprecated or removed.
There are better solutions under the "recommendations" tab at

And I would encourage your updating your version of Mahout to 0.9 or to the

Hi,
New to mahout and fp growth. I havefollowed this
example:https://chimpler.wordpress.com/2013/05/02/finding-association-rules-with-mahout-frequent-pattern-mining/
I generated nice output informationlike this (as an example):
[abc,def,ghi] => klm,confidence:0.597, support:0.01, lift: 57.415, con
certainly be happy about it!
Best,

fpgrowth was initially removed and added again for 0.9 because one specific
user stepped up to support it (and was never heard from again). Mahout 0.9
should have fpgrowth IIRC.

So I know fpgrowth was sent out to pasture a few months ago. As luck would have

Would my only option now be to pull the source (per Sebastian's note in the

Any other options? I
Hello,
I am new to mahout, I wanted information about the mahout project structure
(all the directories info, what they contain, how i can use them) ,
basically I am interested in frequent item mining stuff. Besides this, I
have executed the command
#mahout fpg -i accidents.dat -o patterns -k 50
50 -method mapreduce -regex ´[\
]´ -s 2
kindly tell me the what is the meaning of -k in this command, and how the
output varies if i change he value of k.
.
thanks in advance

Hi,
I saw some similar questions in this mailing list but could not find a
clear answer yet.
With fairly large dataset (330G), the FPGrowth takes most of time in the
parallel-fpgrowth Reduce tasks, can I set the number of Reduce jobs
automatically? In my default Hadoop installation, the number of
Hello,
Could you try re-running FP-Growth with the '-2' flag, and let us know
if you have more success?
This uses an alternate implementation of the FPGrowth algorithm; I have
had problems similar to what you are seeing when using the default
implementation.
I am skeptical of

Hi Jens,
Is it neccessary to use itemsets with equal length?
No - fixed size itemsets are not required.
Is it possible to use itemsets with duplicates in mahout FPGrowth?
Not reliably. This crash looks like it caused by having more items in
one particular itemset than in the set of items
I am using mahout-distribution 0.6. My first test programm of mahout FPGrowth

from 'mapreduce'. I've done this from two different datasets,

Did you try using the bin/mahout script.
Its outdated. This page predates the bin/mahout fpg launcher, so some of the
sections uses the mvn exec plugin directly.

The FPGrowth driver page:
https://cwiki.apache.org/confluence/display/MAHOUT/Parallel+Frequent+Pattern+Mining
gives a command line that only works in mahout/core, rather than
mahout/. Is this drift, or a document bug?

1. A job is killed is a normal behavior. Since by default, hadoop will
enable the speculative executions, which means it will create two attempts
for the same mapper and
once one of the attempt is done, it will just kill the one is not finished.
2. There are lots of possibilities that a mapper tak
