Re: [jira] Commented: (MAHOUT-108) Implementation of Assoication Rules learning by Apriori algorithm

[Pradeep Pujari <pp...@gmail.com>]

How to use Association Rules learning concept in Mahout? For example, based
on purchase history and marketing analytics tool we know the associations
like {shoes, socks} ---> tie meaning customers who buy shoes and socks also
buy ties. Does Mahout recommend products based on association rules.

Thx,
Pradeep.
