In an era where machine learning (ML) models are increasingly being integrated into critical systems, ensuring their integrity and robustness has become a matter of significant concern. One of the most potent threats to ML models is adversarial inputs, which are maliciously crafted inputs designed to manipulate or deceive ML models into making incorrect predictions or decisions. These inputs, often imperceptible to humans, can have severe consequences, ranging from compromising the accuracy and reliability of ML models to posing significant security and safety risks.
