python 中具有固定均值的高斯混合模型估计函数?
Function for estimation of Gaussian Mixture Model with fixed means in python?
有固定均值估计GMM模型的函数吗?到目前为止,我只发现了 sklearn.mixture.GaussianMixture
,但它只采用初始方法,但 AFAIK 无法修复方法。还有其他选择吗?
据我所知(通过查看 this similar question 的答案)不可能对 GMM 使用固定方法。您只能为初始猜测提供值,但对于固定值,您必须更改代码。
有个问题
So it's not possible to force, or restrict the parameters in certain ranges, instead of just initial guesses?
有了答案:
Not without changing the code. As this defeats the whole EM-approach
in my opinion! (but i would not consider myself an expert there).
