Ensemble based Classification Techniques for Concept Drifting in Continuous Data Stream: A Survey
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2016, Vol 4, Issue 12
Abstract
Data Stream Mining is a process of extracting and analyzing the hidden, predictive, knowledge based information from the rapid, fast moving and raw data streams. The technical areas of data stream mining process includes Classification, Clustering, Decision Tree, Association Rule Mining, Temporal Data Mining, Time Series Analysis, Spatial Mining, Web Mining etc. From these technical areas, Stream data classification suffered from a problem of infinite length, concept evaluation, feature evaluation and concept drift. The most challenging problem of data stream is concept-drift which refers to the deviation of data stream from one state to another unpredictable state over time. For example, vital signals of human body like ECG (Electrocardiogram), EEG (Electroencephalogram), and BP (Blood Pressure) etc. are continuous in nature and abruptly changing hence there is a need to apply an efficient real-time data stream mining techniques for taking intelligent health care decisions. In order to address concept drift evolved in these continuous data stream, a classification model must endlessly adapt itself to the most recent concept. Hence, this paper gives the overview of various ensemble based classification algorithm techniques in the field of data stream mining and explores the future directions.
