The k-nearest neighbor(kNN) is improved by applying the distance functions with relearning and ensemble computations with the higher accuracy values. In this study, the proposed relearning and combining ensemble computations are an effective technique for improving accuracy. We develop a new approach to combine kNN classifier based on different distance functions with relearning and ensemble computations. The proposed combining algorithm shows higher generalization accuracy, compared to our previous studies and other conventional algorithms by artificial intelligence techniques. First, to improve classification accuracy, a relearning method with genetic algorithm is developed. Second, ensemble computations are followed by the relearning. Experiments have been conducted on some benchmark datasets from the UCI Machine Learning Repository.
