Anomaly detection has traditionally dealt with record or transaction type data sets. But in many real domains, data naturally occurs as sequences, and therefore the desire of studying anomaly detection techniques in sequential data sets. The problem of detecting anomalies in sequence data sets is related to but different from the traditional anomaly detection problem, because the nature of data and anomalies are different than those found in record data sets. While there are many surveys and comparative evaluations for traditional anomaly detection, similar studies are not done for sequence anomaly detection.
