Subject Re: item-based recommendation for different item
Date Tue, 21 Sep 2010 08:24:36 GMT
What you need is a IDRescorer. Use any Recommender you like, but, pass in a
IDRescorer object too which will boost a recommended item's score if it is
more similar to some target item. For example I might simply multiply by
that similarity score. This should achieve your desired effect.
