K- Means algorithm
algorithm, grouping, java, machine-learning, unsupervised-learning
Solution
Classification, Clustering and grouping are well developed areas of IR. There is a very good (Java) library/software (open source) here Called WEKA. There are several algorithms for clustering there. Although there is a learning curve, it might useful when you encounter harder problems.
Problem
I'm trying to program a k-means algorithm in Java. I have calculated a number of arrays, each of them containing a number of coefficients. I need to use a k-means algorithm in order to group all this data. Do you know of any implementation of this algorithm?
