Hi there, I am writing a Grails plugin for mahout recommender (collaborative filtering) at the moment. As I am beginner of mahout, I have some doubt for the implementation of RecommenderBuilder for SlopeOneRecommender and MySQLJDBCDataModel.
Please see the code at https://github.com/limcheekin/mahout-recommender/blob/master/src/groovy/org/grails/mahout/recommender/SlopeOneRecommenderBuilder.groovy. In line 40, I am getting the MySQLJDBCDataModel externally instead of using the 'dataModel' argument of buildRecommender method. The reason I do so is I have a hard time to cast the dataModel of buildRecommender method to appropriate class which use to instantiate MySQLJDBCDiffStorage object. Is this solution (getting MySQLJDBCDataModel externally) appropriate? Kindly let's me know if you have better and more appropriate solution. Thanks in advanced. Best regards, Chee Kin
