WebFeb 2, 2024 · To overcome the problem of “crowding” and apply to remote sensing data, we search for a new function. This function should be similar with its probably distribution in high-dimensional space and presents explicitly interval between two crests, by measuring similarity between high- and low-dimensional space based on KL divergence. Webt-SNE uses a heavy-tailed Student-t distribution with one degree of freedom to compute the similarity between two points in the low-dimensional space rather than a Gaussian …

Many of you already heard about dimensionality reduction algorithms like PCA. One of those algorithms is called t-SNE (t-distributed Stochastic Neighbor Embedding). It was developed by Laurens van der Maaten and Geoffrey Hinton in 2008. You might ask “Why I should even care?
