Abstract: To overcome the drawbacks that nearest neighbour classification requires huge computation and memory storage, this paper proposes a improved algorithm (different iterative case filtering,DICF). In this algorithm, a set of samples with the poor classification ability is removed from the training set in each iteration until the training set is no longer getting smaller. It can be seen from analysis that time complexity of DICF is O (n~2). The experimental results on some real data sets demonstrate the effectiveness and the feasibility of the proposed algorithm. Compared to traditional methods, such as MCS,ICF and ENN, the condensed sets obtained by DICF is superior in storage and classification accuracy.
