The Manifold visualizer provides high dimensional visualization using manifold learning to embed instances described by many dimensions into 2, thus allowing the creation of a scatter plot that shows latent structures in data. Unlike decomposition methods such as PCA and SVD, manifolds generally use nearest …
WebTo use this for tSNE analysis, the user must select the number of events to be downsampled (plotted as “sample size” in the graphs below), save the layout, wait for the downsampling to finish, and use the tSNE plugin to calculate tSNE. Downsampling time is reflected in the graph below and was ~20 seconds, regardless of the number of events.
