Hi, I was wondering if there is a simple way to sparsify a vector in Mahout. I basically have an n-dimensional vector (currently a DenseVector) and I want to develop a method that sparsifies it by keeping only the largest s values of the vector and setting the rest to 0. Is there a simple solution to this given all that is included in the Vector class or do I need to create my own method?
