WebCustom Distance Function. The syntax of a custom distance function is as follows. function D2 = distfun (ZI,ZJ) tsne passes ZI and ZJ to your function, and your function computes the distance. ZI is a 1-by- n vector containing a single row from X or Y. ZJ is an m -by- n matrix containing multiple rows of X or Y. WebMay 15, 2024 · Projecting data naively can lead to problems so instead you can use a feature embedding method. Here I will give an example for 4 different methods: Isomap, MDS, spectral embedding and TSNE (my favorite). This is continuous data that I have access to but you can easily do the same for clustered data.
