Query: Weakly Supervised Temporal Anomaly Segmentation with Dynamic Time
  Warping   Most recent studies on detecting and localizing temporal anomalies have
mainly employed deep neural networks to learn the normal patterns of temporal
data in an unsupervised manner. Unlike them, the goal of our work is to fully
utilize instance-level (or weak) anomaly labels, which only indicate whether
any anomalous events occurred or not in each instance of temporal data. In this
paper, we present WETAS, a novel framework that effectively identifies
anomalous temporal segments (i.e., consecutive time points) in an input
instance. WETAS learns discriminative features from the instance-level labels
so that it infers the sequential order of normal and anomalous segments within
each instance, which can be used as a rough segmentation mask. Based on the
dynamic time warping (DTW) alignment between the input instance and its
segmentation mask, WETAS obtains the result of temporal segmentation, and
simultaneously, it further enhances itself by using the mask as additional
supervision. Our experiments show that WETAS considerably outperforms other
baselines in terms of the localization of temporal anomalies, and also it
provides more informative results than point-level detection methods.
