abstract = "Data mining is now one of the most active field of
research. Extracting those nuggets of information is
becoming crucial and one of its important technique is
classification. It helps to group the data in some
predefined classes. Various techniques for
classification exists which classifies the data using
different algorithms. Each algorithm has its own area
of best and worst performance. This paper concentrates
on the four most famous algorithms, i.e., Decision
Tree, Naive Bayes, K Nearest Neighbour and Genetic
Programming and the effect on their performance of time
and accuracy when the number of instances are
incrementally decreased. This paper will also
investigate the difference in result when working with
binary class or multiclass datasets and suggest the
algorithms to follow when using certain kind of
dataset.",
