2019-02-01 Predictable t-SNE

t-SNE is quite an interesting tool to visualize data on a map but it has one drawback: results are not reproducible. It is much more powerful than a PCA but the results is difficult to interpret. Based on some experiment, if t-SNE manages to separate classes, there is a good chance that a classifier can get good performances. Anyhow, I implemented a regressor which approximates the t-SNE outputs so that it can be used as features for a further classifier. I create a notebook Predictable t-SNE and a new tranform PredictableTSNE.
