Hello Stuart, Have a look at description of https://issues.apache.org/jira/browse/MAHOUT-872 In a comment there Sebastian also references wiki entry: https://cwiki.apache.org/confluence/display/MAHOUT/Collaborative+Filtering+with+AlS-WR
PredictionJob/predictFromFactorization was replaced with org.apache.mahout.cf.taste.hadoop.als.RecommenderJob = recommendfactorized : Compute recommendations using the factorization of a rating matrix See the RecommenderJob class javadoc for parameters: https://builds.apache.org/job/Mahout-Quality/javadoc/org/apache/mahout/cf/taste/hadoop/als/RecommenderJob.html Kind regards, Stevo Slavic.
