It is well known that many algorithms perform best on data that is standardized, and we use that fact in the next step, by applying SVD on the obtained z-score matrix. 網頁burn_in Number of initial Gibbs samples to be discarded and not included in the compu-tation of final estimates. Details Starting from the data matrix x, the Deep Mixture of Unigrams is fitted and k clusters are obtained. The algorithm for the estimation of the
