After that, the class label of a new test sample is determined according to the class label of the nearest cluster center. While kNN lazy classifier is computationally expensive, MNNCBC classifier reduces its computational complexity by a multiplier of 1/k. So MNNCBC classifier is about k ...

Sir please reply soon... can we use eucledian distance and hamming distance both in knn classifier at the same time??? I am working on a project where I have to classify gabor features using hamming distance and geometrical features using eucledian distance... Is it possible sir???
KNN是一种非参数学习算法,这意味着它不会对底层数据做出任何假设。这是一个非常有用的特性,因为大多数客户的数据并不真正遵循任何理论假设,例如线性可分性,均匀分布等等。 何时应使用KNN? 假设您想要租一间公寓并最近发现您的朋友的邻居可能在两周内将她的公寓出租。由于该公寓尚未出现在租赁网站上,因此您如何尝试...

该函数的输出应该是具有非空名称的数字汇总指标的向量。默认情况下, train 根据预测类别评估分类模型。可选地,类概率也可用于衡量性能。要在重采样过程中获得预测的类概率,参数 classProbs in trainControl 必须设置为 TRUE。这将概率列合并到每个重采样生成的预测中(每个类有一列,列名是类名)。
