-----------------------------------
Hi, I plan to work on it next week. Detect convergence may not be M/R related.
If we would port the ALS to spark, we probably also need to auto detect
convergence. What do you think? And what is the plan to port the ALS to spark?
> Build tools around mahout to check the training error of factorization and
> automatically detect convergence

> Key: MAHOUT-1249
> URL: https://issues.apache.org/jira/browse/MAHOUT-1249
> Project: Mahout
> Issue Type: Improvement
> Components: Collaborative Filtering
> Affects Versions: 1.0
> Reporter: Saikat Kanjilal
> Fix For: 1.0

>
> The goal of this task is to check the training error of the factorization
> during the computation to make it automatically detect convergence. The goal
> is not to have to specify the number of iterations as a parameter needed for
> convergence.
