Exercise

Data masking with PCA

PCA for pseudo-anonymization is widely used among companies. You can find multiple Kaggle challenges and datasets where the data is provided after PCA transformations.

A differentially private version of PCA is also included in the diffprivlib in the models module. It's based on the PCA class from sklearn but including optional arguments for epsilon and min and max bounds. Just as we have seen in the previous chapter.

In this exercise, you will apply data masking with PCA on the NBA Salaries dataset, already loaded as players.
