A new research paper published on arXiv details a method to prevent model extraction in contextual linear optimization systems. These systems, often used in predict-then-optimize (PTO) frameworks, aim to provide optimal decisions without revealing their internal cost vectors. The paper identifies conditions under which an attacker can learn the underlying prediction model by observing decisions across various contexts, particularly for linear models. To counter this, a defense mechanism is proposed that perturbs decisions when the predicted cost vector is close to a decision boundary, with experiments showing this defense can increase extraction error.
