WebMATLAB code for the noise swiss roll dataset. Input: the number of datasets: ; noise parameter: Output: swiss roll dataset, noiseless and noise: Height = 30 rand (n, 1); Webt-Distributed Stochastic Neighbor Embedding (t-SNE) is a technique for dimensionality reduction that is particularly well suited for the visualization of high-dimensional datasets. The technique can be implemented via Barnes-Hut approximations, allowing it to be applied on large real-world datasets.
