Meta Monitoring System

Various software approaches exist that determine whether a given instrumented system is experiencing anomalous behavior. Many anomaly detection systems simply generate some type of deviation score, then rely on a subject matter expert to evaluate the data and recommend a course of action. These evaluations are often nontrivial and can lead to false alarms. NASA’s Meta Monitoring System (MMS) helps one to better interpret such deviation scores and determine whether detected anomalous behavior is transient or systemic.
