Hi All, I want to build a recommender engine using cf of Mahout with a dataset as below: <user,car1-rating,car2-rating, ............carn-rating> where user is string value and ratings are numeric.
Mahout seems to support <userid,itemid,rating> with numerical values directly, but is there a way to support a dataset like above by building a custom FileDataModel? Or do we need to convert the dataset to the Mahout supported dataset format? I am new to Mahout. Please provide me an example where possible. Thanks in advance, Naveen
