cv.EM/CovarianceMatrixType - MATLAB File Help |
Constraint on covariance matrices which defines type of matrices.
Possible values:
mu_k*I
. There is the only
parameter mu_k
to be estimated for each matrix. The option may
be used in special cases, when the constraint is relevant, or as a
first step in the optimization (for example in case when the data
is preprocessed with cv.PCA). The results of such preliminary
estimation may be passed again to the optimization procedure, this
time with CovarianceMatrixType='Diagonal'
.d
for each matrix. This is most
commonly used option yielding good estimation results.d^2/2
. It is not
recommended to use this option, unless there is pretty accurate
initial estimation of the parameters and/or a huge number of
training samples.Constant | false |
