Dynamic baseline anomaly detection

WebA change within a data pattern, an outlier, or an event that falls outside of a standard trend. A deviation from something expected or something that doesn’t conform to expectations. An anomaly, or an outlier in a pattern, can be indicative of something that falls outside of the norm or something that is possibly not right. Webwere used for anomaly detection. Node attributes assumed to have constant values, and is not applicable for our problem. Another paper that studies anomaly detection using locality statistics is [7], where the problem again is to detect anomaly in time series of graphs with time-dependent edges and fixed nodes’ attributes.
