In the bigera where human intelligence is being enhanced by machine intelligence through artificial intelligence (AI), machine learning (ML), big data and computer vision. However, prediction models trained using in-house training dataset suffer from two well-known problems: (1) The prediction accuracy of a trained model heavily depends on the generalization of the training dataset and may suffer from poor accuracy for unseen data inputs. (2) A privately trained prediction model is vulnerable to adversarial inputs, which manipulates the prediction outputs with only a black box access to a learning as a service API, turning a learning system against itself through input data poisoning attacks. In this talk, I will describethe formal metrics to quantitatively evaluate and measure the robustness of a trained prediction model against unseen inputs in the presence of different adversarial settings and share some of our current research results.An important takeaway message is that the defense mechanisms for guarding the robustness of a deep learning system should be geared towards improving the generalization properties of the target learning system.
