Build a differentially private classifier

In this exercise, you will build and train a private Gaussian Naive Bayes model on the Penguin dataset to classify if a penguin is male or female.

K-anonymity doesn't work well with high dimensional or diverse datasets due to its substantial theoretical and empirical limitations, the "curse of dimensionality". As the number of features or dimensions grows, the amount of data we need to generalize accurately grows exponentially. It's one of the reasons why differential privacy is the current preferred privacy model. Epsilon is independent of any background knowledge and "bounds" the sensitive information.

The DataFrame is loaded as penguin_df and split into X_train, y_train, X_test and y_test. The private model class has been imported as dp_GaussianNB.

Get ready to apply anonymization techniques such as data suppression, masking, synthetic data generation, and generalization. In this chapter, you’ll learn how to distinguish between sensitive and non-sensitive personally identifiable information (PII), quasi-identifiers, and the basics of the GDPR. You'll also encounter real-life examples of what can go wrong if you don't follow these best practices.

Discover how to anonymize data by sampling from datasets following the probability distribution of the columns. You’ll then learn how to apply the k-anonymity privacy model to prevent linkage or re-identification attacks and use hierarchies to perform data generalization in categorical variables.

Learn about differential privacy, the model used by major technology companies such as Apple, Google, and Uber. In this chapter, you’ll explore data by generating private histograms and computing private averages in data. You’ll also create differentially private machine learning models that allow businesses to increase the utility of their data.

In this final chapter, you’ll learn how to apply dimensionality reduction methods such as principal component analysis (PCA) to anonymize large multi-column datasets. You’ll then use Faker to generate realistic and consistent datasets, and scikit-learn to create synthetic datasets that follow a normal distribution. Lastly, you’ll tie everything you learned in this course together as you combine multiple techniques to safely release datasets to the public.
