Prevedere gli stipendi

In questo esercizio userai il dataset del censimento dei redditi per prevedere se le persone hanno uno stipendio superiore a $50K/anno oppure no.

Ricorda che quando crei il modello privato dovresti specificare i limiti come parametro, per evitare ulteriore perdita di privacy o fuoriuscite di informazioni. Di solito puoi scegliere i limiti in modo indipendente dai dati, usando la conoscenza del dominio oppure effettuando una ricerca con un istogramma DP.

Il dataset è stato caricato e diviso in X_train, y_train, X_test e y_test. Il classificatore è disponibile come dp_GaussianNB.

Istruzioni dell'esercizio

Imposta i limiti del modello calcolando i valori min e max nei dati di training e aggiungendo rumore casuale sottraendo e aggiungendo numeri casuali in un intervallo da 5 a 40 per le 5 colonne dei nostri dati.
Crea un classificatore dp_GaussianNB con un epsilon di 0.5 e i limiti creati in precedenza.
Esegui il fit del modello sui dati e osserva lo 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: Introduzione alla differential privacy Exercise 2: Epsilon (ϵ): il numero magico Exercise 3: Istogrammi con privacy differenziale Exercise 4: Budget di privacy Exercise 5: Uso dei budget di privacy Exercise 6: Quando non resta budget Exercise 7: Esplorare i dati con un gestore del budget di privacy Exercise 8: Modelli di Machine Learning con privacy differenziale Exercise 9: Crea un classificatore con privacy differenziale Exercise 10: Prevedere gli stipendi

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.
