1 Jul 2016Pankaj Malhotra • Anusha Ramakrishnan • Gaurangi Anand • Lovekesh Vig • Puneet Agarwal • Gautam Shroff

Mechanical devices such as engines, vehicles, aircrafts, etc., are typically instrumented with numerous sensors to capture the behavior and health of the machine. For instance, manual controls and/or unmonitored environmental conditions or load may lead to inherently unpredictable time-series. We show that EncDec-AD is robust and can detect anomalies from predictable, unpredictable, periodic, aperiodic, and quasi-periodic time-series.
