Hi there: I've successfully used a hadoop program to calculate the diff-matrix, and stored the data in my HDFS...
But now I'm confusing, how can I read the users' profile as well as the diff-matrix at the same time(they are at different location in my HDFS) to predict a specific user's ratings? I've already checked the mahout implementation of Slopeone with hadoop, but that one just did the calculation of diff-matrix.. and no prediction part is included... Anyone can help me? How to read two kinds of data in Hadoop program at the same time? -- Name: Ke Xie Eddy Research Group of Information Retrieval State Key Laboratory of Intelligent Technology and Systems Tsinghua University
