Salarissen voorspellen

In deze oefening gebruik je de census-inkomensgegevens om te voorspellen of iemand meer dan $50K/jaar verdient of niet.

Vergeet niet dat je bij het maken van het private model de grenzen als parameter moet opgeven, zodat er geen extra privacyverlies of informatielek optreedt. Meestal kun je de grenzen onafhankelijk van de data kiezen, op basis van domeinkennis of door te zoeken met een DP-histogram.

De gegevensset is geladen en opgesplitst in X_train, y_train, X_test en y_test. De classifier is beschikbaar als dp_GaussianNB.

Stel de grenzen van het model in door de min- en max-waarden in de trainingsdata te berekenen en willekeurige ruis toe te voegen door respectievelijk willekeurige getallen in het bereik 5 tot 40 af te trekken en op te tellen voor de 5 kolommen in onze data.
Maak een dp_GaussianNB-classifier met een epsilon van 0.5 en de zojuist bepaalde grenzen.
Fit het model op de data en bekijk de score.

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.

Exercise 1: What's private, and why do we care?Exercise 2: Privacy is power Exercise 3: Is it sensitive or non-sensitive?Exercise 4: Suppression of sensitive attributes Exercise 5: Data masking and data generation with Faker Exercise 6: Masking sensitive PII Exercise 7: Removing names with faker Exercise 8: Anonymizing with data generalization Exercise 9: Reducing identification risk with generalization Exercise 10: Data aggregation and data generalization Exercise 11: Top and bottom coding White House salaries

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.

Exercise 1: Anonymizing categorical data Exercise 2: Explore the distribution of data Exercise 3: Sampling from the same probability distribution Exercise 4: Anonymizing continuous data Exercise 5: Different distributions Exercise 6: Sampling from the best continuous distribution Exercise 7: Introduction to K-anonymity Exercise 8: Privacy attributes Exercise 9: Generalizing into ranges Exercise 10: Generalizing data using hierarchies Exercise 11: Using hierarchies for categorical data Exercise 12: K-anonymizing a dataset

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.

Exercise 1: Introductie tot differential privacy Exercise 2: Epsilon (ϵ): het magische getal Exercise 3: Histogrammen met differential privacy Exercise 4: Privacybudgetten Exercise 5: Privacybudgetten gebruiken Exercise 6: Wanneer er geen budget meer is Exercise 7: Data verkennen met een privacybudget-accountant Exercise 8: Differentiële private Machine Learning-modellen Exercise 9: Bouw een differentieel privéklaasificador Exercise 10: Salarissen voorspellen

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.
