Motivation And Importance

This section emphasizes the critical role of privacy in machine learning, especially when dealing with sensitive data, and outlines key threats to user privacy.

Threat Models

This section introduces the concept of threat models in machine learning, distinguishing between white-box and black-box attacks.

Definitions

This section defines critical privacy metrics used in machine learning, including differential privacy and traditional metrics like k-anonymity, l-diversity, and t-closeness.

Differential Privacy (Dp)

Differential Privacy provides a framework for ensuring data privacy in machine learning by guaranteeing that an individual's data cannot significantly influence the output of a model.

What Is Differential Privacy?

Differential privacy ensures that data analysis results are not significantly affected by the inclusion or exclusion of an individual's data, providing formal guarantees against data leakage.

Mechanisms For Dp

This section outlines mechanisms used to implement Differential Privacy, focusing on the Laplace, Gaussian, and Exponential mechanisms to protect sensitive data.

Dp In Ml Training

Differentially Private Stochastic Gradient Descent (DP-SGD) incorporates noise into gradient updates in ML training to ensure data privacy.

Practical Considerations

This section discusses the trade-offs between privacy and utility in machine learning, focusing on parameters that influence differential privacy.

Federated Learning (Fl)

Federated Learning enables decentralized model training while enhancing data privacy by keeping data local.

Overview

This section introduces Federated Learning (FL) as a decentralized approach for training machine learning models while preserving data locality and privacy.

Advantages For Privacy

Federated Learning significantly enhances privacy by reducing direct exposure of raw data.

Challenges

This section addresses the primary challenges faced in federated learning, including communication overhead, data heterogeneity, and security threats from malicious clients.

Robustness In Machine Learning

This section focuses on the importance of robustness in machine learning, emphasizing how models can remain accurate despite various adversarial challenges.

Understanding Robustness

Robustness in machine learning refers to the ability of models to maintain performance despite adversarial attempts to disrupt them.

Types Of Attacks

Defending Against Adversarial Attacks

This section addresses various strategies for defending machine learning models against adversarial attacks.

Adversarial Training

Adversarial training involves training machine learning models with inputs that have been intentionally modified to challenge their robustness.

Defensive Distillation

Defensive distillation is a technique that improves model robustness by training a new model using the softened outputs of a pre-existing model, thereby obscuring its gradients.

Input Preprocessing Defenses

Input preprocessing defenses enhance machine learning model robustness against adversarial attacks by modifying input data before it is processed.

Certified Defenses

Certified defenses provide formal and mathematical guarantees of a machine learning model's robustness against adversarial attacks.
