Simply put, it projects the high-dimensional data points … WebFeb 28, 2024 · Since one of the t-SNE results is a matrix of two dimensions, where each dot reprents an input case, we can apply a clustering and then group the cases according to their distance in this 2-dimension map. Like a geography map does with mapping 3-dimension (our world), into two (paper). t-SNE puts similar cases together, handling non-linearities ...
WebOne very popular method for visualizing document similarity is to use t-distributed stochastic neighbor embedding, t-SNE.
