alignment               Align the initializations.
alignment_swap          Complete the alignment of initializations based
                        on the output of function 'alignment_swap'.
data_generation         Generate data for simulations.
estimation_error        Caluclate the estimation error of GMM
                        parameters under the MTL setting (the worst
                        performance among all tasks).
initialize              Initialize the estimators of GMM parameters on
                        each task.
misclustering_error     Calculate the misclustering error given the
                        predicted cluster labels.
mtlgmm                  Fit binary Gaussian mixture models (GMMs) on
                        multiple data sets under a multi-task learning
                        (MTL) setting.
predict_gmm             Clustering new observations based on fitted GMM
                        estimators.
tlgmm                   Fit the binary Gaussian mixture model (GMM) on
                        target data set by leveraging multiple source
                        data sets under a transfer learning (TL)
                        setting.
