InstanceList.sampleWithWeights介绍

[英]Returns an InstanceList of the same size, where the instances come from the random sampling (with replacement) of this list using the given weights. The length of the weight array must be the same as the length of this list The new instances all have their weights set to one.
[中]返回相同大小的InstanceList，其中实例来自使用给定权重对此列表的随机抽样（替换）。权重数组的长度必须与此列表的长度相同。新实例的权重都设置为1。
