Abstract
This thesis studies how to keep personal data safe in machine learning by using Differential Privacy (DP). It tests several models Logistic Regression, Decision Trees, Naive Bayes, and Neural Networks on the Adult Income dataset. The models are trained on both original and DP protected data with different privacy budgets. Naive Bayes works well with DP because it is simple and uses probability. Ensemble models also keep good accuracy across privacy levels. Neural Networks with DP-SGD balance accuracy and privacy, helping reduce privacy attacks. The study suggests using Naive Bayes, ensemble models, and DPSGD for real world use where both privacy and accuracy matter.
