Gradient Masking Definition

Gradient Masking is a defense technique in machine learning used to prevent adversaries from exploiting model gradients. By modifying or "masking" the gradients, this method aims to prevent attackers from successfully performing adversarial attacks, which could otherwise reveal sensitive information about the model's parameters or data. Gradient Masking is crucial in safeguarding models from gradient-based attacks, especially in deep learning applications.

Gradient Masking Explained Easy

Imagine a map showing a path, but some parts are erased to hide where you’re going. In Gradient Masking, the "path" or gradients in a machine learning model are hidden or scrambled, making it hard for attackers to follow and misuse it.

Gradient Masking Origin

Gradient Masking originated as a response to the rising threat of adversarial attacks in machine learning. As AI applications expanded, researchers developed methods like Gradient Masking to secure machine learning models against potential vulnerabilities exposed by adversarial gradients.

Gradient Masking Etymology

The term derives from "gradient," which indicates the directional change used in model optimization, and "masking," which implies hiding or altering.

Gradient Masking Usage Trends

In recent years, Gradient Masking has seen increased attention in the AI security community. As models become more complex, Gradient Masking and related techniques are deployed to enhance security in sensitive areas like finance, healthcare, and autonomous systems.
