我正在使用SMOTE機制來過濾數據集，但過濾器操作往往失敗。由於「distanceToInstance」計算和比較造成的doSMOTE故障
我發現我在doSMOTE功能，在這種情況下，路線原因：計算實例之間
1-距離。
2的情況下，根據使用比較這些距離下令：
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);
}
但在這個階段 - 在Java的comparison-規則被打破，則拋出異常。
我懷疑是因爲我的實例太靠近對方了。在這篇文章的末尾附上一段距離。
我的問題是：
1-這是一個合理的情況嗎？
2-有沒有辦法繞過它？
3-如果SMOTE在這種情況下無效 - 您可以推薦哪種過濾器？
的距離的採樣：
