Hamming Distance汉明距离
汉明距离是使用在数据传输差错控制编码里面的,汉明距离是一个概念,它表示两个(相同长度)字对应位不同的数量,我们以d(x,y)表示两个字x,y之间的汉明距离。对两个字符串进行异或运算,并统计结果为1的个数,那么这个数就是汉明距离。 在信息论中,两个等长字符串之间的汉明距离是两个字符串对应位置的不同字符...

反距离权重插值inverse distance weighting,IDW
反距离权重 (IDW) 插值显式假设:彼此距离较近的事物要比彼此距离较远的事物更相似。当为任何未测量的位置预测值时,反距离权重法会采用预测位置周围的测量值。与距离预测位置较远的测量值相比,距离预测位置最近的测量值对预测值的影响更大。反距离权重法假定每个测量点都有一种局部影响,而这种影响会随着距离的增...
