In order to classify the enormous students into the defined classes some technique must be applied. There are number of techniques introduced in educational data mining for the classification of data. K-Nearest Neighbor, Support Vector Machine, Genetic Algorithm have been discussed in this article. ...
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...

K近邻算法,即K-Nearest Neighbor algorithm,简称KNN算法,单从名字来猜想,可以简单粗暴的认为是:K个最近的邻居,当K=1时,算法便成了最近邻算法,即寻找最近的那个邻居。为何要找邻居?打个比方来说,假设你来到一个陌生的村庄,现在你要找到与你有着相似特征的人群融入他们,所谓入伙。 用官方的话来说,所谓K近邻算法...
