WebOct 17, 2024 · So you cannot use a t-SNE model to predict a projection on new data without doing a refit. On the other hand, I would not give the output of a t-SNE as input to a classifier. Mainly because t-SNE is highly non linear and somewhat random and you can get very different outputs depending with different runs and different values of perplexity.
