Data flow mining and anomaly detection

Presented are data streams, tasks and challenges of mining the data stream. The emphasis is on practical work, which presents the detection of abnormalities, a special form of data mining. Participants get familiar with storing the data stream, which is vital for data mining and anomaly detection.


  • Data flows
    • Model of the data stream, the sampling and filtering of the data in the stream, counting the various elements in the stream, evaluating events, counting the elements in the interval
  • Anomaly Detection
    • What are the anomalies, challenges/tasks of detection of anomalies, types of anomalies and anomaly detection methods, applications for detecting anomalies
  • Cassandra presentation and benefits
  • Example of processing of the data stream
  • Interval storage of data in Cassandra
  • Implementation of counting the elements in the interval
  • Detection of sudden jumps occurrence of the event as an example of detection of anomalies

Target group

Načrtovalci IoT in Big Data storitev
