Алгоритми FLARS та виділення аномалій часових рядів

As a rule, algorithms of recognition of time series anomalies are based on time frequency or statistical analysis . This article is devoted to detailed formal description of new fuzzy set based algorithm FLARS (Fuzzy Logic Algorithm for Recognition of Signals). It recognizes time series anomalies by means "smooth" modelling (in fuzzy mathematics sense) of interpreter's logic, which searches for anomalies at the record.Общепринятые алгоритмы выделения аномалий временных рядов основываются, в основном, на частотно временном или статистическом анализе. Статья посвящена строгому построению нового алгоритма FLARS. Его можно рассматривать как результат "мягкого" (на основе нечеткой математики) моделирования логики интерпретатора, ищущего аномалии на записи.Загальноприйняті алгоритми виділення аномалій часових рядів базуються, як правило, на частотно часовому або статистичному аналізі. Стаття присвячена строгій побудові нового алгоритму FLARS.

Strong Earthquake-Prone Areas in the Eastern Sector of the Arctic Zone of the Russian Federation

This paper continues the series of publications by the authors on the recognition of areas prone to the strongest, strong, and significant earthquakes using the FCAZ system-analytical method. The areas prone to earthquakes with M ≥ 5.5 in the eastern sector of the Arctic zone of the Russian Federation were recognized. It is shown that certain potential high seismicity zones are well confined to the boundaries of the Eurasian, North American, and Okhotsk tectonic plates. In addition, according to the results of the FCAZ recognition, some areas located at a sufficient distance from the main tectonic structures of the studied region were also recognized as highly seismic. The results of the study, among other factors, justify the use of the assessment of the completeness magnitude in the catalog for choosing the set of recognition objects for the FCAZ method
