Abstract

We present concept drift responsive method for classifier training for sequential data. Relevant instance selection for training is based on similarity to the target observation. Similarity in space and in time is combined. The algorithm determines an optimal training set size. It can be used plugging in different base classifiers. The proposed algorithm shows the best accuracy in the peer group. The algorithm complexity is reasonable for the field applications.
