The resulting vector space is of very high dimensionality, thus cannot be easily visualized. To reduce the high dimensional space to three.dimensions the method ''t-distributed stochastic neighbor embedding'' is used, which keeps words close together that are close in the high dimensional space. | The resulting vector space is of very high dimensionality, thus cannot be easily visualized.
