They implemented a LSH algorithm to find the closest neibourhoods and the algorithm is fast for that. Can we implement one and contribute into the mahout project? Any suggestions? paper is here: http://iws.seu.edu.cn/resource/Proceedings/WWW/2007/papers/paper570.pdf Cheers -- Name: Ke Xie Eddy Research Group of Information Retrieval State Key Laboratory of Intelligent Technology and Systems Tsinghua University --00504502cb2821295c04a0c7a11b--
