Statistical wavelet-based anomaly detection in big data with compressive sensing

Abstract: Anomaly detection in big data is a key problem in the big data analytics domain. In this paper, the definitions of anomaly detection and big data were presented. Due to the sampling and storage burden and the inadequacy of privacy protection of anomaly detection based on uncompressed data, compressive sensing theory was introduced and used in the anomaly detection algorithm. The anomaly detection criterion based on wavelet packet transform and statistic process control theory was deduced. The proposed anomaly … Show more

“…For example, for a 2000-mAh (milliamperes per hour) battery operating with 3.7 volts, the mobile edge device can last for around 16 h in LA mode, 140 h in CA mode and around 20 h in CLA mode. The battery time was calculated using Equation (9). Here, "P" represents the power.…”
