FPG uses a lot of boxed primitives - this patch eliminates a bunch of
List<Integer>
------------------------------------------------------------------------------------
Key: MAHOUT-921
URL: https://issues.apache.org/jira/browse/MAHOUT-921
Project: Mahout
Issue Type: Improvement
Components: Frequent Itemset/Association Rule Mining
Affects Versions: 0.6
Reporter: tom pierce
Priority: Minor
TransactionTree uses List<Integer> internally and as part of its API; this
patch changes that and pushes the use of List<Integer> down to FPGrowth.java.
This can be converted if the perf bug can be fixed (MAHOUT-890). I will also
provide an alternate base FPGrowth implementation.
Please note that this patch assumes the patch attached to MAHOUT-920 has
already been applied.
