Observe means "add an observation" in the sense of a statistical sample containing a number of observations.
The s0, s1 and s2 instance variables are, I think, the respective sums of coordinate-wise powers of the observed data (except for s0 which would be the same for all coordinates). It is a known issue that accumulating the moments in this fashion is numerically unstable. 2011/11/5 WangRamon <[email protected]> > > > > > Hi Mahout users I'm evaluating the cluster feature and reading > AbstractCluster class, can you tell me where can i find more > documents/explaination about the "observe" methods in this class and the > s0, s1, s2 parameters, thanks in advance.
