Hi, I suppose this a combination of a generic machine learning question and a mahout question. I have a data set. A user may or may not be part of a funded scheme. If there are not part of the funded scheme they might be susceptible to certain problems a, b, c and d. If there are part of the funded scheme they might incur problems a, b and c but not d. I want to process the data set to infer something like people who *are* part of funded scheme won't encounter problem c and d. Is this a recommendation or a classification - How do I approach this? Also can hive inteactt with mahout - I read (correct me if I'm wrong) that it's probably best to input data to mahout in csv format - I assume this is possible with hive? many thanks. -- View this message in context: http://lucene.472066.n3.nabble.com/How-to-approach-this-Classification-vs-Recommendation-tp3984795.html Sent from the Mahout User List mailing list archive at Nabble.com.
