Python Scikit学习对混合数据进行聚类（数字和分类）
有人可以帮助修改下面的工作示例，从共享数据创建集群吗 该示例使用Scikit Learn的均值漂移聚类来识别农艺设施中类似/共定位植物物种的斑块 在这类问题中，除了使用数值外，还曾提出过关于使用分类值的类似问题，但我认为此示例有所不同，原因如下：此问题中的非数值不能简单地用一个和零个伪值进行编码。例如，我们不能对“马兜铃属植物”和“马兜铃属植物”这样的值进行热编码，因为在名称上具有这种相似性的物种需要根据其家族聚集在一起，除了X和Y值所给出的地理接近度之外。在创建集群时，名称的相似性与位置同样重要 我尝试过两件事：为物种名称中的字母指定任意数字值，以表明拼写相似的名称在数字行上更接近。我打算对这些值应用自动缩放，并插入到带有X和Y坐标的脚本中。这不起作用，因为不同的名字在数字上非常相似 我的另一个尝试是通过使用Levenstein距离来合并分类值。但距离的输出仅基于比较两个值。如果输出显示每个字符串与所有其他字符串之间的距离，如何将该结果作为Meanshift算法的输入 无论如何，这里是数据和工作脚本，目前只使用数值。 我真的很感激任何关于如何使用分类值的相似性对这些数据进行聚类的例子 多谢各位Python Scikit学习对混合数据进行聚类（数字和分类）,python,machine-learning,scikit-learn,levenshtein-distance,mean-shift,Python,Machine Learning,Scikit Learn,Levenshtein Distance,Mean Shift,有人可以帮助修改下面的工作示例，从共享数据创建集群吗 该示例使用Scikit Learn的均值漂移聚类来识别农艺设施中类似/共定位植物物种的斑块 在这类问题中，除了使用数值外，还曾提出过关于使用分类值的类似问题，但我认为此示例有所不同，原因如下：此问题中的非数值不能简单地用一个和零个伪值进行编码。例如，我们不能对“马兜铃属植物”和“马兜铃属植物”这样的值进行热编码，因为在名称上具有这种相似性的物种需要根据其家族聚集在一起，除了X和Y值所给出的地理接近度之外。在创建集群时，名称的相似性与位置同样重
