Overview
In poisoning attack, attacker designed noises- such as variables value changes, label changes- are induced to the training data to test fidelity and robustness of model training. The model trained on such adverse dataset could systematically result in model vulnerability issues. For example, in anomaly detection model the anomalous training samples are fed with back door object (possibly signature pattern) and modify the label to non-anomalous. This solution measures the effect of adversarial backdoor attacks during training on model robustness and performance.
Highlights
- Model Robustness is the immunity of ML model towards any intended attack to alter its performance. Poisoning attacks are intended to degrade the performance of tabular data classifier by injecting adverse/modified data samples to training phase. This solution identifies the robustness of image classifier by performing a Black box poisoning attack. Imputing a back door- which is an attacker designed noise- to the training data samples typically results in outcome of trained model to drift to the existence of back door, leading to compromise of model security.
- The solution requires a labeled (original) training dataset and a pre-trained Keras model with structural information. The user can define the backdoor pattern and select the class labels and sample of original training data to impute. The Keras model is trained with imputed (attacked) data. The number of data points of selected label to perturb can be controlled by the user. The difference in accuracies of the target model over the samples with attacked class label to those samples with non-attacked class labels give the robustness of the model to poison attack.
