The callable This page shows the popular functions and classes defined in the sklearn.metrics.pairwise module. This method takes either a vector array or a distance matrix, and returns a distance matrix. pairwise_distance在sklearn的官网中解释为“从X向量数组中计算距离矩阵”，对不懂的人来说过于简单，不甚了了。 实际上，pairwise的意思是每个元素分别对应。因此pairwise_distance就是指计算两个输入矩阵X、Y之间对应元素的 metrics. That's because the pairwise_distances in sklearn is designed to work for numerical arrays (so that all the different inbuilt distance functions can work properly), but you are passing a string list to it. Here is the relevant section of the code def update_distances(self, cluster_centers, only_new=True, reset_dist=False): """Update min distances given cluster centers. If metric is âprecomputedâ, X is assumed to be a distance matrix. Compute the euclidean distance between each pair of samples in X and Y, where Y=X is assumed if Y=None.
