Subject: MultivariateNormalMixtureExpectationMaximization only 1 dimension
Hi,
Hi,
Full disclosure, I'm not a mathematician so I can not go into the weeds into
the math. However I am tasked with porting some matlab code that is doing
gaussian mixed model to java. I really want to use apache common math if
possible. However the code that I'm porting has 1 dimension ( a
Hi,
I think this is a bug in the
MultivariateNormalMixtureExpectationMaximization class. When I update the
code to allow 1 column in the rows it outputs a similar fit to matlab.
Here's an example of Matlab:
X = [normrnd(0, 1, 100, 1); normrnd(2, 2, 100, 1)]
GMModel = fitgmdist(X,2);
>> GMModel.m
Yes thank you! As you stated you should be able to have a single column with n
components (having enough data samples of course).. Having your fix would
allow me to port this code over from what I see.
Thx!
