Definition: In this task, you are given the abstract of a research paper. Your task is to generate a summary of this abstract. Your summary should not be very short, but it's better if it's not more than 30 words.
Input: This work views neural networks as data generating systems and applies anomalous pattern detection techniques on that data in order to detect when a network is processing a group of anomalous inputs.   Detecting anomalies is a critical component for multiple machine learning problems including detecting the presence of adversarial noise added to inputs. More broadly, this work is a step towards giving neural networks the ability to detect groups of out-of-distribution samples.   This work introduces ``Subset Scanning methods from the anomalous pattern detection domain to the task of detecting anomalous inputs to neural networks.   Subset Scanning allows us to answer the question: "``Which subset of inputs have larger-than-expected activations at which subset of nodes? "  Framing the adversarial detection problem this way allows us to identify systematic patterns in the activation space that span multiple adversarially noised images.   Such images are ``"weird together".   Leveraging this common anomalous pattern, we show increased detection power as the proportion of noised images increases in a test set.    Detection power and accuracy results are provided for targeted adversarial noise added to CIFAR-10 images on a 20-layer ResNet using the Basic Iterative Method attack.

The paper proposed a scheme to detect the presence of anomalous inputs based on a "subset scanning" approach to detect anomalous activations in the deep learning network.
