Have any one know recommendation algorithm in mahout for finding support and confidence from given datasets of User id , Item id and Item preference value..And based on that information the algorithm recommends items...
The concepts of support and confidence do not quite apply to item-based recommender algorithms. So in that sense the answer is 'no'.
I can guess what you may have in mind, which is related but different. Please clarify what exactly you want to do or extract in your question if so.
