Comparison doSMOTE因“故障”导致的故障；“距离指示器”；计算与比较

我使用SMOTE机制来过滤我的数据集，但是过滤操作往往会失败

我在doSMOTE函数中找到了我的案例的原因，其中：

1-计算实例之间的距离

2-使用比较器根据这些距离对实例进行排序：

public int compare(Object o1, Object o2) {
      double distance1 = (Double) ((Object[]) o1)[0];
      double distance2 = (Double) ((Object[]) o2)[0];
      return (int) Math.ceil(distance1 - distance2);
} 

但是在这个阶段，Java的比较规则被打破，并引发异常

我怀疑原因是我的实例彼此太接近。远处的一瞥附在这篇文章的末尾

我的问题是：

1-这是合理的情况吗

2-有没有办法绕过它

3-如果SMOTE在这种情况下不起作用-您可以推荐其他哪种过滤器

什么是失败消息，异常？是的，空指针异常。stacktraces不包含任何信息-显示空指针异常，而不仅仅是我的代码中对SMOTE调用的引用。
