Subject Re: Clustering without Hadoop
Date Mon, 02 Dec 2013 03:55:27 GMT
Thanks, Suneel, I'll try this way.

In this recommender example:
https://github.com/ManuelB/facebook-recommender-demo/blob/master/src/main/java/de/apaxo/bedcon/AnimalFoodRecommender.java#L142
,

they only use mahout api. So I am thinking that can I do the clustering
similarly.
