Problem 5: Stability and Robustness of Neural Networks to Adversarial Perturbations Statement: Prove that under certain regularity conditions (e.g., Lipschitz continuity of activation functions and bounded weights), a neural network classifier is robust to adversarial perturbations of the input. Specifically, establish bounds on the size of perturbations that the network can withstand without changing its classification output. Key Points for the Proof: • • Define the notion of adversarial perturbations and robustness in the context of neural networks. Utilize Lipschitz continuity to relate input perturbations to changes in the network's output. Derive bounds on perturbation magnitudes based on the network's architecture and weight norms. Ensure that the conditions imposed on the network parameters are sufficient to guarantee robustness.
