Abstract:

   An approach to solve the problem of anomalies operative detection in monitoring data using adaptive digital filtering based on an orthogonal filter using FFT decomposition is proposed. A mathematical simulation and a real-time clustering procedure was performed. The work of the proposed approach is exemplified by the sampling Sevastopol water area sampling data using a hydrological SVP probe.

Keywords: monitoring, mathematical modeling, Big Data, digital filtering, discrete Fourier transform, detection of anomalies, clustering, critical systems, data mining.
