Abstract. — k Nearest Neighbor (KNN) strategy is a notable classification strategy in data mining and estimations in light of its direct execution and colossal arrangement execution. In any case, it is outlandish for ordinary KNN strategies to select settled k esteem to all tests. Past courses of action assign different k esteems to different test tests by the cross endorsement strategy however are typically tedious. In previous work proposes new KNN strategies, first is a KTree strategy to learn unique k esteems for different test or new cases, by including a training arrange in the KNN classification. This work additionally proposes a change rendition of KTree technique called K*Tree to speed its test organize by putting additional data of the training tests in the leaf node of KTree, for example, the training tests situated in the leaf node, their KNNs, and the closest neighbor of these KNNs. K*Tree, which empowers to lead KNN arrangement utilizing a subset of the training tests in the leaf node instead of all training tests utilized in the recently KNN techniques. This really reduces the cost of test organize.
KNN method is popular because of its simple implementation and works incredibly well in practice. KNN is considered a lazy learning algorithm that classifies the datasets based on their similarity with neighbors. But KNN have some limitations which affects the efficiency of result. The main problem with the KNN is that it is lazy learner as well as the KNN does not learn from the training data which affects the accuracy in result. Also KNN algorithm computation cost is quite high. So, these problems with KNN algorithm affect the accuracy in result and overall efficiency of algorithm. This work proposes the new KNN strategies KTree and K*Tree are more productive than the conventional KNN strategies. There are two recognized contrasts between the past KNN strategies and proposed KTree strategy. In the first place, the past KNN methods have no training stage, while KTree method has a sparse-based preparation stage, whose time complexity is O(n2). Second, the previous methods need at least O(n2) time complexity to obtain the ideal-k-values due to involving a sparse-based learning process, while KTree method just needs O(log(d) + n) to do that via the learned model. In this work, additionally stretch out proposed KTree technique to its change rendition called k*Tree strategy to speed test organize, by just putting additional data of training tests in the left node, for example, the training tests, their KNNs, and the closest neighbors of these closest neighbors. KTree methods learns different set samples and add a training stage in the traditional KNN classification. The K*Tree speed up its test stage. This reduces running cost of its stage.
