The SpatialEM is a new robust EM algorithm for the finite mixture learning procedures. The algorithm utilizes median based location and rankbased scatter estimators to replace sample mean and sample covariance matrix in each M step, hence enhancing stability and robustness of the algorithm. To understand more about this algorithm, read the article ''Yu, K., Dang, X., Bart Jr, H. and Chen, Y. (2015). Robust Model based Learning via SpatialEM Algorithm. IEEE Transactions on Knowledge and Data Engineering, 27(6), 16701682. doi:10.1109/TKDE.2014.2373355''.
