Data streaming is the transmission of a
continuous data stream which is often fed into stream
processing software to produce insightful data. A
collection of data elements arranged chronologically
make up a data stream. The two methods used to classify
data streams are single and ensemble classification. The
single classification technique is quick and uses less
memory for processing, but as the number of unknown
patterns or samples rises, its efficiency declines. The
ensemble technique can be utilized for two main reasons.
Compared to a single model, an ensemble model can
perform better and result with accurate predictions.
Ensemble learning (EL) generates various base
classifiers form which a new classifier is produced that
efficiently performs than other traditional classifiers. In
addition to the algorithm, hyperparameters,
representation and training set, these base classifiers
may differ in the type of classification. A dynamic
ensemble learning (DEL) is a sort of EL algorithm which
automatically selects the subset of the ensemble members
while making the prediction. The primary benefit of
DEL is improved predictive accuracy when compared to
normal EL. This paper study and analyse various
dynamic ensemble classifier model for data stream
classification. The identification of merit and demerit of
these methods help to understand the available problems
and motivate researchers to find out new solutions for
the listed problem.
