KNN也称作K最邻近结点算法(k-Nearest Neighbor algorithm)的缩写形式,是分类预测的经典算法之一。在煤炭勘探过程中,往往希望将新勘探出来的煤炭产品分类预测,并采取对应类别的煤炭处理和保存措施。文中,将采用基于特征选择的KNN分类算法应用到煤炭勘探分类预测工作中,该方法首先选择煤炭分类中有价值的特征属性,并使用KNN算法完成分类工作。该算法可以有效地提高煤炭分类预测工作的效率,并且有助于煤炭后续的保存和精加工措施。
KNN也稱作K最鄰近結點算法(k-Nearest Neighbor algorithm)的縮寫形式,是分類預測的經典算法之一。在煤炭勘探過程中,往往希望將新勘探齣來的煤炭產品分類預測,併採取對應類彆的煤炭處理和保存措施。文中,將採用基于特徵選擇的KNN分類算法應用到煤炭勘探分類預測工作中,該方法首先選擇煤炭分類中有價值的特徵屬性,併使用KNN算法完成分類工作。該算法可以有效地提高煤炭分類預測工作的效率,併且有助于煤炭後續的保存和精加工措施。

KNN is called K-Nearest neighbor algorithm, and it is one of classic algorithms. In the process of coal exploration, we usually want to classify the explored coal, and adopt some measures to deal with and store the coal products. In this paper, we apply the feature selection based KNN classification algorithm into the coal exploration classification forecast, and this method firstly select the valuable attributes and use the KNN algorithm to complete the classification work. The algorithm could promote the efficiency of the classification forecast, and it is helpful for further storage and fine finishing work.
