Added a script implementing tSNE with a pca-preprocessed input data. This script implements the concept used in sklearn's tSNE, where they provide the option of pre-processing the input data with pca before giving them to the tSNE algorithm. For very large datasets, this could theoretically improve tSNE performance by removing a large portion of noise prior to the core algorithm. However, the current implementation does not speed up tSNE when applied on MNIST, so further research required to confirm this. -- This is an automated message from the Apache Git Service.
