Hi all,
I have a question when I use RecommenderJob for item-based recommendation. My input data format is "userid,itemid,1", so I set booleanData option is true. The length of users is 9,000,000 but the length of item is 200. When I run the RecommenderJob, the result is null. I try many times use different arguments. But the result is also null. This is one of my commands. Would you help me for tell me why it is null please? bash recommender-job.sh --input input/user-item-value --output output/recommender --numRecommendations 10 --similarityClassname SIMILARITY_PEARSON_CORRELATION --maxSimilaritiesPerItem 300 --maxPrefsPerUser 300 --minPrefsPerUser 1 --maxPrefsPerUserInItemSimilarity 10000000 --booleanData true Thanks
