Table 2 shows that the GMMs
exhibited the best forecast quality measures, corresponding to the highest values of DAC and lowest errors (MAE, RMSE, MAPE, RAE and RRSE), compared to SMMs and UMs.
Let M(h) denotes the mean supervector in a GMM
which is related to languages and channels.
Gaussian mixture models (GMM
) have been introduced for speaker verification  and become the dominant modeling approach until recently.
The initial user initializations are interpolated in the corresponding slices to mark the thyroid and nonthyroid regions (i.e., foreground and background) and create corresponding GMMs
. The aforementioned processes are then repeated in each individual images to segment all the thyroid in the dataset.
It is worthwhile noting that, after multiple statistical fits of the empirical data to GMMs
, we decided to abandon the GMM
in favor of a simple Gaussian fit since the latter performs comparably with the former with respect to classification while being much less computationally intensive.
Then the system uses GMM
model to filter the top 20 results, extracts the GMM
main color feature, and computes the similarity of them.
HMMs differ from GMMs
in terms of input temporal evolution.
Similarly, another colour image indexing method through spatiochromatic multi-channel GMM
was introduced by Piatek and Smolka .

In this case, in order to obtain a uniform distribution, length of GMMs
near the center is supposed to be shorter and therefore sets a lower boundary for parametrical optimization:
Gaussian mixture models (GMMs
) were used to estimate the intensity distributions of foreground/background seeds .
Even if the orthogonality of the regressors to the error is violated, this log-linear specification is easily extended to the linear GMMs
