In-Mapper combiner design pattern

Hi, Recently we started to use the in-mapper combiner design patterns in our hadoop based algorithms at Alpine Data Labs; those algorithms include variable selection using info gain, decision tree, naive bayes model and SVM, and we found that we can have 20~40% performance speedup without doing to

PCA in mahout

Hi folks, I'm trying to use mahout's PCA implementation based on SSVD in our application. I understand that in order to avoid densifying the sparse input, mahout provides an option that the mean of cols can be a parameters to pass into the algorithms. However, a lot of time, the scale of each axis
