WebSep 28, 2024 · T-distributed neighbor embedding (t-SNE) is a dimensionality reduction technique that helps users visualize high-dimensional data sets. It takes the original data that is entered into the algorithm and matches both distributions to determine how to best represent this data using fewer dimensions. The problem today is that most data sets … 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 ...
