Therefore, we propose an automatic fast double KNN classification algorithm on the basis of automatically determining the cluster centers and hierarchical clustering. We introduce automatically determining the cluster centers into the KNN in training process. Namely, big data samples are divided into ...
3.1. Algorithm of BFS-kNN In general, a data point p can be defined as a D dimensional vector: p = [d1, d2,…, dD]. The database DB is defined as a set of N data points: DB = {p1, p2,…, pN}. Given a query data point q, kNN searches for k data points in a databa...
