WebJan 31, 2024 · For PCA the code is very similar but we use the PCA class instead of TSNE. I did both the 2d and 3d projections similar to t-SNE. However, there is one additional parameter that you need to keep in mind for PCA. This is the explained_variance_ratio_. This tells you the amount of variance from your data that the principal components capture.
