Adversarial Detection and Correction by Matching Prediction Distributions

1 code implementation21 Feb 2020 Giovanni Vacanti, Arnaud Van Looveren

We present a novel adversarial detection and correction method for machine learning classifiers. The detector consists of an autoencoder trained with a custom loss function based on the Kullback-Leibler divergence between the classifier predictions on the original and reconstructed instances. The method is unsupervised, easy to train and does not require any knowledge about the underlying attack.
