Hello!
We are trying to use PredictionIO (ver. 0.9.5) + Universal Recommender (v. 0.2.3) for building personal recommendations for users of our service.
EventServer is collecting events about user's rating of items in MySQL database, Recommender's retrain runs by scheduler and storing personal recommendations to ElasticSearch. At beginning and some later trains, recommender's response looks nice with many items, but after a while, count of recommendations begins to decline. We looked at the data in the ElasticSearch: items exists, but their properties are erased.
We would like to know why that can happen?
