Description

Goal is to speed up rule generation. The arules package in R limits posterior to 1.

In MADlib the goal of the feature is to allow users to specify number of posterior items to 1 or 2 or ... with the goal of reducing run-time.

Does it make sense to specify number of anterior items too?
