Subject sampling bestseller buyers for recommendations
Date Mon, 26 Dec 2011 22:01:59 GMT

I am trying to achieve some item-to-item-recommendations and the setup
works quite well. But one thing I stumbled across is that some items are so
popular that they are a recommendation for nearly every other item. In the
Amazon paper they say that they are sampling the bestseller buying
customers. Do I have to do this preprocessing step myself or does Mahout
help with that?
