The discrete signal is received, and a sequence of likelihoods corresponding to the sample values in the signal is generated. The likelihoods are based at least in part on a historical probability distribution of previously received sample values, and a likelihood is a probability of occurrence of a corresponding sample value in the signal. Likelihood change points are identified in the likelihood sequence, and the discrete signal is segmented into a plurality of segments at samples corresponding to the identified change points. A segment is identified as an anomaly based on a comparison between a statistic of the segment and a statistic of the historical probability distribution."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Statistics-based anomaly detection","description":"Systems and methods are described herein for detecting an anomaly in a discrete signal, where samples in the signal correspond to amounts of data flow in a network within a time interval.
