本文主要是介绍daily pattern AD,对大家解决编程问题具有一定的参考价值,需要的程序猿们随着小编来一起学习吧!
Thinkings:
- Anomalous patterns may represent anomalous events. what does an anomalous pattern mean in energy consumption?W
- measurement/manual operation errors, instrument failure, XX human activities. 比如窃电行为,偷入住行为。
what is the necessity of extracting anomalous knowledge?
- they affect the models related to forecasting and analysis.
- The anomaly may be related to XX events. -----> early warning and prevention of XX disasters, and to reduce economic and social losses.
- What algorithms are used in energy domains? What algorithms are used in other fields? Can they be used in energy fields? if not, why?
- other domains:
- SAX, convert TS into symbolic TS; then top-k pattern anomalies are analyzed and verified from the candidate pattern anomalies.
- formalize normal patterns, define a temporal similarity score between sequences. and then detect abnormal patterns which do not match or deviate from normal patterns.
