Statistical machine learning with Gaussian distributions

2013-05-10 Thread Matthew McClain
I'm pretty new to Mahout, but it looks like there aren't any statistical machine learning algorithms that use Gaussian distributions. Specifically, I'm thinking of clustering algorithms that use Gaussian distributions to model clusters and hidden Markov models that use Gaussian distributions. Can

Karan, Without knowing why clustering didn't work, it's hard to say what a better approach would be. Any other information you can give about the problem you're working on would probably help, too. In particular, how did you come up with your four categories? Typically, categories are not defined

Re: How to identify Clusters using KMeans

2013-05-07 Thread Matthew McClain
Karan, The clusters that come out of the KMeans algorithm won't necessarily fit the categories that you've defined. It all depends on the data. For example, the clusters could all be in a line (like at (6,6), (3,3), (-3, -3), and (-6, -6)), so there's no cluster that fits the description High
