1. A method for detecting anomalies in time series data, comprising the steps of:
- comparing universal features extracted from testing time series data with the universal features acquired from training time series data to determine a score, wherein the universal features characterize trajectory components of the time series data and stochastic components of the time series data; and
detecting an anomaly if the anomaly score is above a threshold, wherein the steps are performed in a processor.

Abstract
A method detects anomalies in time series data by comparing universal features extracted from testing time series data with the universal features acquired from training time series data to determine a score. The universal features characterize trajectory components of the time series data and stochastic components of the time series data. Then, an anomaly is detected if the anomaly score is above a threshold.
