The main directions of our research include predictive modeling, cluster analysis, anomaly detection and resembling tasks, whereby we focus on intelligent adaptive approach. The methods range from statistics to machine learning methods, for some kind of problems we have also used biologically inspired computing. We work with static as well as with stream data, in both cases our datasets meet the requirements of Big Data. Currently we evaluate our results in the domain of energy and on datasets generated in bioinformatics research.

Keywords:
Data Streams and Batch Data, Data Clustering, Anomaly Detection, Prediction, Big Data, Specific kinds of data, e.g. those generated in bioinformatics research
