Skip to main content Welcome to {{displayDomain}} , a US site operated by Expedia, Inc. We propose an extension of the k nearest neighbor (kNN) classifier to time-series classification using intervals' numbers (INs). Each core is treated as an independent computer, meaning we have to have R running separately on each core. To run the knn() function, we need to supply the test case(s), which corresponds to a point sitting approximately in the middle of the distance between A and B. We will investigate the utility of machine learning for detecting cancer by applying the kNN algorithm to measurements of biopsied cells from women with abnormal breast masses. For each row of the test set, the k nearest (in Euclidean distance) training set vectors are found, and the classification is decided by majority vote, with ties broken at random. minimum vote for definite decision, otherwise doubt.
