normalized_mutual_info_score(labels_true, labels_pred, *, average_method='arithmetic') 两个聚类之间的标准化互信息。 归一化互信息 (NMI) 是互信息 (MI) 分数的归一化,用于在 0(无互信息)和 1(完全相关)之间缩放结果。在此函数中,互信息通过 H(labels_true) 和H(labels_pred)) 的一些广义平均值...
使用 sklearn 0.20.0,我将提供一个合成示例来重现该问题:metrics.normalized_mutual_info_score([0]*100001, [0]*100000 + [1])metrics.normalized_mutual_info_score([0]*110001, [0]*110000 + [1])我希望下面的答案是 0,但我分别得到了 7.999 和 -7.999。 查看完整描述1 回答江户川乱折腾 TA贡献...
