Segmentasi pelanggan

Dalam latihan ini, Anda akan melakukan Segmentasi Pelanggan dari Mall Customer Segmentation Dataset menggunakan model clustering yang bersifat differentially private.

Pada clustering K-means, Anda dapat menghitung jumlah cluster yang optimal dengan metode elbow.

Grafik hasil dari metode Elbow dengan model non-private

Dari grafik tersebut, perhatikan bahwa jumlah cluster yang optimal adalah 5. Anda akan melakukan clustering berdasarkan Annual Income dan Spending Score, yang telah dimuat sebagai X, lalu memplot cluster yang dihasilkan.

Seluruh himpunan data telah dimuat sebagai mall_df. Untuk memudahkan, fungsi kustom show_clusters() disediakan untuk memplot cluster. Gunakan ?show_clusters untuk mempelajarinya lebih lanjut.

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: Pengantar differential privacy Exercise 2: Epsilon (ϵ): angka ajaib Exercise 3: Histogram dengan differential privacy Exercise 4: Anggaran privasi Exercise 5: Menggunakan privacy budget Exercise 6: Saat tidak ada anggaran tersisa Exercise 7: Menjelajah data dengan privacy budget accountant Exercise 8: Model Machine Learning dengan differential privacy Exercise 9: Membangun classifier yang differentially private Exercise 10: Memprediksi gaji Exercise 11: Model klastering dengan differential privacy Exercise 12: Pra-pemrosesan data Exercise 13: Segmentasi pelanggan

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.

Exercise 1: PCA for anonymization Exercise 2: Anonymization of high-dimensional data Exercise 3: Data masking with PCA Exercise 4: Generating realistic datasets with Faker Exercise 5: Consistent synthetic dataset Exercise 6: Datasets with the same probabilistic distribution Exercise 7: Creating synthetic datasets using scikit-learn Exercise 8: Generating datasets for classification Exercise 9: Generating datasets for clustering Exercise 10: Safely release datasets to the public Exercise 11: Exploring and pseudonymizing a dataset Exercise 12: Preparing employee data for safe release Exercise 13: Great work!
