Coupled IGMM-GANs for deep multimodal anomaly detection in human mobility data

  title={Coupled IGMM-GANs for deep multimodal anomaly detection in human mobility data},
  author={Kathryn Gray and Daniel Smolyak and Sarkhan Badirli and George O. Mohler},
Detecting anomalous activity in human mobility data has a number of applications including road hazard sensing, telematic based insurance, and fraud detection in taxi services and ride sharing. In this paper we address two challenges that arise in the study of anomalous human trajectories: 1) a lack of ground truth data on what defines an anomaly and 2) the dependence of existing methods on significant pre-processing and feature engineering. While generative adversarial networks seem like a…
